# Singularity Cloud Network — Compute & Grid

Products share one credit balance and one set of wallet/API-key auth:

- **SGL Machines** — provision, manage, resize, and extend GPU/VPS instances on Vultr or DigitalOcean. **API base:** `https://compute.x402layer.cc`
- **AI Machines** — one-click deploy of a **GPU already running an LLM**, mode chosen at deploy: `private` (your own **OpenAI-compatible** endpoint — returns URL + API key) or `grid` (serve as a node & earn USDC + SGL, needs 50k SGL staked). Same x402 lifecycle as Machines; add `model_id` + `mode` to provision. **Standard tier (not confidential).** See [AI Machines](#ai-machines--one-click-llm-gpu) below and `references/ai-machines.md`.
- **SGL Grid** — decentralized, confidential (TEE), **OpenAI-compatible** inference across attested nodes; token streaming + end-to-end encryption. **API base:** `https://grid.x402compute.cc` (see [SGL Grid — Inference](#sgl-grid--inference) below)
- **Provide Compute (run a node)** — turn a TEE-capable machine into a grid node: stake $SGL, register, attest, serve a model, earn USDC + SGL. Agentic via the `sgl` CLI. Operators can set a **custom per-token price** within a band (`sgl price set`, suggested × 0.5–× 5); callers compare nodes via `GET /v1/providers`. See [Provide Compute](#provide-compute-run-a-node) below and `references/node-operator.md`.
- **SGL Processors** — serverless TEE functions. *Coming soon.*

Pay with x402, MPP, or pre-loaded credits — the same `x402c_…` API key and prepaid credit balance work across Machines and Grid.

**x402 Networks:** Base (EVM) • Solana • MegaETH • Robinhood Chain (EVM)
**x402 Currency:** USDC (Base/Solana) • USDm (MegaETH) • USDG (Robinhood Chain)
**MPP Methods:** Tempo • Stripe/card when enabled by the service
**Credits:** Pre-load USD via x402 topup, then provision/extend (`use_credits: true`) or call the Grid with `X-API-Key`
**Protocol:** HTTP 402 Payment Required (`X-Payment` for x402, `Authorization: Payment` for MPP)
**$SGL:** native token, live on Solana — mint `5c4HyD2rSShqnTsf5z3SaoD2H3GE452u2CUuYjviBAGS` (staking secures the grid; see [staking.x402layer.cc](https://staking.x402layer.cc))

This section below (Machines) covers provisioning. Jump to **[SGL Grid — Inference](#sgl-grid--inference)** for the OpenAI-compatible inference API.

**Access Note:** Preferred access is SSH public key. If no SSH key is provided, a one-time password fallback can be fetched once via API.
**DigitalOcean Note:** DigitalOcean instances require SSH key access because one-time root passwords are not exposed through the DigitalOcean API.

## Quick Start

### 1. Install Dependencies
```bash
pip install -r {baseDir}/requirements.txt
```

### 2. Choose Wallet Mode

#### Option A: Direct signing keys (Base, MegaETH, Robinhood, or Solana)

> **Use a dedicated low-balance wallet.** Never use your primary custody wallet.

```bash
# Base (EVM) — same keys work for MegaETH and Robinhood Chain
export PRIVATE_KEY=<your-evm-private-key>
export WALLET_ADDRESS=<your-evm-wallet-address>

# MegaETH (uses same EVM keys as Base)
export PRIVATE_KEY=<your-evm-private-key>
export WALLET_ADDRESS=<your-evm-wallet-address>
export COMPUTE_AUTH_CHAIN="megaeth"

# Robinhood Chain (uses same EVM keys as Base; pays with USDG)
export PRIVATE_KEY=<your-evm-private-key>
export WALLET_ADDRESS=<your-evm-wallet-address>
export COMPUTE_AUTH_CHAIN="robinhood"

# Solana
export SOLANA_SECRET_KEY=<your-solana-secret-key>
export SOLANA_WALLET_ADDRESS=<your-solana-wallet-address>
export COMPUTE_AUTH_CHAIN="solana"
```

#### Option B: OpenWallet / OWS (optional-first)
```bash
npm install -g @open-wallet-standard/core@0.5.0
export OWS_WALLET="compute-wallet"
export COMPUTE_AUTH_MODE="ows"
```

Create `COMPUTE_API_KEY` (optional) for management endpoints:
```bash
python {baseDir}/scripts/create_api_key.py --label "my-agent"
```

OWS is best for compute auth and routine management flows. Direct x402 provision and extend still use local payment-signing paths. MPP provision/extend should use `mppx` or Tempo Wallet.

Resize is a management action, not a second payment flow. The API preserves remaining prepaid dollar credit by recalculating `expires_at` for the target hourly rate after the provider accepts the resize.

---

## ⚠️ Security Notice

> **IMPORTANT**: This skill handles private keys for signing blockchain transactions.
>
> - **Never use your primary custody wallet** - Create a dedicated wallet with limited funds
> - **Private keys are used locally only** - They sign transactions locally and are never transmitted
> - **For testing**: Use a throwaway wallet with minimal USDC/USDm

## Instance Lifecycle

```
Browse Plans → Choose Provider/Plan → Provision (x402/MPP/Credits) → Active → Extend / Destroy → Expired
```

Instances expire after their prepaid duration. Extend before expiry to keep them running.

## Workflows

### A. Browse and Provision

```bash
# List GPU plans
python {baseDir}/scripts/browse_plans.py

# Filter by type (gpu/vps/high-performance)
python {baseDir}/scripts/browse_plans.py --type vcg

# Check available regions
python {baseDir}/scripts/browse_regions.py

# Generate a dedicated SSH key once (recommended for agents)
ssh-keygen -t ed25519 -N "" -f ~/.ssh/x402_compute

# Provision an instance for 1 month (triggers x402 payment)
python {baseDir}/scripts/provision.py vcg-a100-1c-2g-6gb lax --months 1 --label "my-gpu" --ssh-key-file ~/.ssh/x402_compute.pub

# DigitalOcean plans are prefixed with do:
# They require SSH key access.
python {baseDir}/scripts/provision.py do:s-1vcpu-1gb nyc3 --days 1 --label "do-test" --ssh-key-file ~/.ssh/x402_compute.pub

# Provision a daily instance (cheaper, use-and-throw)
python {baseDir}/scripts/provision.py vc2-1c-1gb ewr --days 1 --label "test-daily" --ssh-key-file ~/.ssh/x402_compute.pub

# Provision for 3 days
python {baseDir}/scripts/provision.py vc2-1c-1gb ewr --days 3 --label "short-task" --ssh-key-file ~/.ssh/x402_compute.pub

# Provision on Solana
python {baseDir}/scripts/provision.py vc2-1c-1gb ewr --months 1 --label "my-sol-vps" --network solana --ssh-key-file ~/.ssh/x402_compute.pub

# Provision on MegaETH (pays with USDm)
python {baseDir}/scripts/provision.py vc2-1c-1gb ewr --months 1 --label "my-mega-vps" --network megaeth --ssh-key-file ~/.ssh/x402_compute.pub

# Provision on Robinhood Chain (pays with USDG — same EVM keys as Base)
python {baseDir}/scripts/provision.py vc2-1c-1gb ewr --months 1 --label "my-usdg-vps" --network robinhood --ssh-key-file ~/.ssh/x402_compute.pub

# Provision via MPP / mppx (Tempo by default; Stripe/card if your mppx config supports it)
npx mppx https://compute.x402layer.cc/compute/provision \
  -X POST \
  -J '{"plan":"vc2-1c-1gb","region":"ewr","os_id":2284,"label":"mpp-vps","prepaid_hours":24,"ssh_public_key":"ssh-ed25519 AAAA... agent"}'

# If the response includes management_api_key, store it for later instance management:
export COMPUTE_API_KEY="x402c_..."

# ⚠️ After provisioning, wait 2-3 minutes for Vultr to complete setup
# Then fetch your instance details (IP, status):
python {baseDir}/scripts/instance_details.py <instance_id>
```

### B. Manage Instances

```bash
# Optional: create a reusable API key (avoids message signing each request)
python {baseDir}/scripts/create_api_key.py --label "my-agent"

# List all your instances
python {baseDir}/scripts/list_instances.py

# Get details for one instance
python {baseDir}/scripts/instance_details.py <instance_id>

# Optional fallback if no SSH key was provided during provisioning
python {baseDir}/scripts/get_one_time_password.py <instance_id>

# Extend by 1 day
python {baseDir}/scripts/extend_instance.py <instance_id> --hours 24

# Extend by 1 month
python {baseDir}/scripts/extend_instance.py <instance_id> --hours 720

# Extend via MPP. MPP extension requires compute auth; use the management API key
# returned from MPP provisioning or normal wallet signature auth.
npx mppx https://compute.x402layer.cc/compute/instances/<instance_id>/extend \
  -X POST \
  -H "X-API-Key: $COMPUTE_API_KEY" \
  -J '{"extend_hours":720}'

# Resize via bundled helper script
python {baseDir}/scripts/resize_instance.py <instance_id> vc2-2c-4gb

# Resize in place with management auth only (no x402 or MPP payment)
curl -X POST https://compute.x402layer.cc/compute/instances/<instance_id>/resize \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $COMPUTE_API_KEY" \
  -d '{"plan":"vc2-2c-4gb"}'

# DigitalOcean disk growth is irreversible and must be confirmed explicitly
curl -X POST https://compute.x402layer.cc/compute/instances/<instance_id>/resize \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $COMPUTE_API_KEY" \
  -d '{"plan":"do:s-2vcpu-4gb","confirm_disk_resize":true}'

# Destroy
python {baseDir}/scripts/destroy_instance.py <instance_id>
```

### C. OpenWallet / OWS

```bash
# List local OWS wallets
python {baseDir}/scripts/ows_cli.py wallet-list

# Sign a Base-compatible compute auth message
python {baseDir}/scripts/ows_cli.py sign-message --chain eip155:8453 --wallet compute-wallet --message "hello"

# Sign a MegaETH-compatible compute auth message
python {baseDir}/scripts/ows_cli.py sign-message --chain eip155:4326 --wallet compute-wallet --message "hello"

# Sign a Solana-compatible compute auth message
python {baseDir}/scripts/ows_cli.py sign-message --chain solana --wallet compute-wallet --message "hello"

# Create an OWS agent key
python {baseDir}/scripts/ows_cli.py key-create --name codex-compute --wallet compute-wallet
```

### D. Credits (payment-free provisioning)

```bash
# Top up credits via x402 payment (one-time)
curl -X POST https://compute.x402layer.cc/compute/credits/topup \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $COMPUTE_API_KEY" \
  -d '{"amount": 100, "network": "base"}'
# Returns 402 → pay → credits added to wallet balance

# Check credit balance
curl https://compute.x402layer.cc/compute/credits/balance \
  -H "X-API-Key: $COMPUTE_API_KEY"

# Provision using credits (no x402/MPP payment needed)
curl -X POST https://compute.x402layer.cc/compute/provision \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $COMPUTE_API_KEY" \
  -d '{
    "plan": "vc2-1c-1gb",
    "region": "ewr",
    "os_id": 2284,
    "label": "credit-vps",
    "prepaid_hours": 720,
    "ssh_public_key": "ssh-ed25519 AAAA... agent",
    "use_credits": true
  }'

# Extend using credits
curl -X POST https://compute.x402layer.cc/compute/instances/<instance_id>/extend \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $COMPUTE_API_KEY" \
  -d '{"extend_hours": 720, "use_credits": true}'
```

Credits are scoped per wallet. If the cloud provider rejects the instance after credits are deducted, the full amount is automatically refunded.

## x402 Payment Flow

1. Request provision/extend → server returns `HTTP 402` with payment requirements
2. Script signs payment locally:
   - Base: USDC `TransferWithAuthorization` (EIP-712)
   - MegaETH: USDm ERC-2612 `permit` (EIP-712) — gasless for the user, facilitator settles on-chain
   - Robinhood Chain: USDG `TransferWithAuthorization` (EIP-3009, EIP-712) — gasless for the user, facilitator settles on-chain in a single tx (domain `name="Global Dollar"`, `version="1"`, chainId `4663`)
   - Solana: signed SPL transfer transaction payload
3. Script resends request with `X-Payment` header containing signed payload
4. Server verifies payment, settles on-chain, provisions/extends instance

MegaETH uses an embedded facilitator (no external CDP dependency). The user signs an off-chain ERC-2612 permit, and the facilitator calls `permit()` + `transferFrom()` on MegaETH (~10ms blocks, near-zero gas).

Robinhood Chain also uses an embedded facilitator (no third party). The user signs an off-chain EIP-3009 `TransferWithAuthorization` for USDG (`0x5fc5360D0400a0Fd4f2af552ADD042D716F1d168`, 6 decimals), and the facilitator submits `transferWithAuthorization()` on Robinhood Chain (chainId 4663) in a single transaction — the contract self-verifies the signature, nonce, and balance on-chain.

For Solana, transient facilitator failures can happen. Retry once or twice if you get a temporary 5xx verify error.

## MPP Payment Flow

MPP is available side-by-side with x402 on the same paid endpoints.

1. Request provision/extend -> server returns `HTTP 402` with `WWW-Authenticate: Payment`
2. `mppx` or Tempo Wallet creates an MPP credential
3. Client retries with `Authorization: Payment ...`
4. Server verifies the MPP payment, provisions/extends the instance, and returns `Payment-Receipt`

Notes:
- `POST /compute/provision` can be paid via MPP without wallet auth. In that case the response includes `management_api_key`; store it because it is shown once and is required for later management.
- `POST /compute/instances/:id/extend` via MPP requires compute auth, usually `X-API-Key: $COMPUTE_API_KEY`.
- `POST /compute/instances/:id/resize` uses compute auth only. It preserves remaining prepaid value by changing expiry instead of charging again.
- x402 remains fully supported through the Python scripts and `X-Payment` header flow.
- MPP methods are service-configured. Tempo is used by default by `mppx`; Stripe/card requires a Stripe-capable MPP client/config.

## AI Machines — One-Click LLM GPU

One-click deploy of a **GPU that comes up already running an LLM**. Same x402 lifecycle as any
Machine (provision / extend / resize / destroy) — you just add `model_id` + `mode` to provision.
Two modes, chosen at deploy:

- **`private`** — your own **OpenAI-compatible** endpoint. The box runs `llama-server` exposing
  `POST /v1/chat/completions` and `GET /v1/models`; the provision response returns the **endpoint URL
  + API key**. Works with any OpenAI-compatible client/agent/router → **OpenRouter-ready**. (Listing it
  *as an OpenRouter provider* is a separate OpenRouter approval — roadmap only.)
- **`grid`** — serve as a grid node and **earn USDC + SGL** (requires **≥ 50,000 $SGL staked**).

**Tier:** Standard (**not** confidential/TEE — for confidential inference use the Grid below or a TEE
node). **Managed:** kept alive, auto-updates (allowlist-gated), SSH available. An **agent with a
funded wallet can deploy + extend + destroy entirely via x402.**

```bash
# Deploy a PRIVATE OpenAI-compatible LLM endpoint (returns endpoint + API key)
python {baseDir}/scripts/provision.py vcg-a100-1c-2g-6gb lax --days 1 --label "my-llm" \
    --model-id llama-3.2-3b --mode private

# Deploy a GRID node (join the grid & earn; wallet needs 50k SGL staked)
python {baseDir}/scripts/provision.py vcg-a100-1c-2g-6gb lax --months 1 --label "grid-node" \
    --model-id llama-3.2-3b --mode grid

# Use a private endpoint (OpenAI-compatible)
curl -X POST <ENDPOINT>/v1/chat/completions \
  -H "Content-Type: application/json" -H "Authorization: Bearer <RETURNED_API_KEY>" \
  -d '{"model":"llama-3.2-3b","messages":[{"role":"user","content":"Hello"}]}'

# Extend runtime before it expires (most-used lifecycle action)
python {baseDir}/scripts/extend_instance.py <instance_id> --hours 720

# Destroy when done
python {baseDir}/scripts/destroy_instance.py <instance_id>
```

Control API: `POST /compute/provision` (add `model_id`+`mode`; base fields `plan`,`region`,`os_id`),
`GET /compute/instances`, `GET /compute/instances/:id`, `POST /compute/instances/:id/extend`,
`POST /compute/instances/:id/resize`, `POST /compute/instances/:id/password`,
`DELETE /compute/instances/:id`, `POST /compute/credits/topup`. Full detail + the end-to-end agent
deploy example → **`references/ai-machines.md`**.

---

## SGL Grid — Inference

Decentralized, confidential inference across attested TEE nodes — **OpenAI-compatible**, so any OpenAI SDK works by pointing `base_url` at the grid. Requests are end-to-end encrypted and can stream token-by-token.

**API base:** `https://grid.x402compute.cc`
**Auth:** `X-API-Key: x402c_…` (billed to your prepaid credits — same key/credits as Machines) **or** per-request x402 via `X-Payment`.
**Billing:** pay-per-token in USDC (credits or x402). No subscription.

| Method | Path | Purpose |
|--------|------|---------|
| `GET`  | `/v1/models` | List models currently served by active attested nodes |
| `POST` | `/v1/chat/completions` | OpenAI-compatible chat (set `"stream": true` to stream) |
| `GET`  | `/grid/capacity` | Live capacity: active nodes, TEE types, served models, `at_capacity` |

```bash
# 1) Reuse your compute API key (x402c_…) + prepaid credits, or create one:
python {baseDir}/scripts/create_api_key.py --label "my-agent"   # → x402c_...
# Top up credits in the dashboard: Settings → Credits (cloud.x402compute.cc).

# 2) Check what's being served + whether the grid has capacity
curl https://grid.x402compute.cc/v1/models -H "X-API-Key: $COMPUTE_API_KEY"
curl https://grid.x402compute.cc/grid/capacity            # active_nodes, models, at_capacity

# 3) OpenAI-compatible chat (billed to credits)
curl -X POST https://grid.x402compute.cc/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $COMPUTE_API_KEY" \
  -d '{"model":"llama-3.2-3b","messages":[{"role":"user","content":"Hello"}]}'

# Streaming: add "stream": true and read the SSE token chunks.
# Pay-per-request with x402 instead of credits: send the X-Payment header
# (same 402 → sign → resend flow as provision/extend) and omit X-API-Key.
```

Use any **OpenAI SDK** by setting `base_url=https://grid.x402compute.cc/v1` and `api_key=$COMPUTE_API_KEY`. Before a large batch, check `/grid/capacity` and back off / retry if `at_capacity` is true.

---

## Provide Compute (run a node)

The other side of the grid: turn a **TEE-capable machine** into a node that serves confidential,
OpenAI-compatible inference and **earns USDC + SGL** per settled job. Fully agentic — the installer
and the `sgl` CLI are shell commands. Full runbook (requirements, flags, maintenance, slashing,
earnings) → **`references/node-operator.md`**.

**Prerequisites:** a supported TEE (e.g. Apple Secure Enclave `apple_se`, Intel TDX/SGX, AMD SEV-SNP,
AWS Nitro), `llama.cpp` + a GGUF model, and **≥ 50,000 $SGL staked** to your operator (Solana) wallet.

```bash
# 1. Stake ≥50,000 SGL to your operator wallet (agentic via the x402-layer skill / Staking Engine API,
#    or at https://staking.x402layer.cc). Non-custodial; slashable only for proven tampering.

# 2. Install the node CLI + runtime, get a model
curl -sSf https://grid.x402compute.cc/install.sh | sh     # installs `sgl` (Singularity-Layer/sgl-network-node)
brew install llama.cpp                                     # local inference runtime (macOS)
#   download a GGUF, e.g. ~/models/Llama-3.2-3B-Instruct-Q4_K_M.gguf

# 3. Register the node under the staked wallet (headless / agentic)
sgl init --wallet <STAKED_WALLET> --tee-type apple_se --models llama-3.2-3b
#   (interactive alternative: `sgl login`)

# 4. Attest the enclave (required before jobs; re-run after any binary update)
sgl attest

# 5. Serve as a background service (production)
sgl service install \
  --model-path ~/models/Llama-3.2-3B-Instruct-Q4_K_M.gguf \
  --model-name llama-3.2-3b \
  --resource-percent 50

# verify
sgl status
curl https://grid.x402compute.cc/grid/capacity            # your node raises active_nodes / models
```

**Maintenance:** `sgl off-grid` (stop new jobs cleanly for planned downtime — no penalty) / `sgl on-grid`
(resume). Honest downtime is never slashed; only proven tampering is. Re-run `sgl attest` after binary
updates. Docs: `https://docs.x402layer.cc/cloud/provide/node-setup`.

## OWS scope note

OWS support is optional-first in this release:
- use it for compute auth and management/API-key flows
- keep direct Base, MegaETH, Robinhood, or Solana signing keys for the paid provision and extend flows
- resize, list, details, password fallback, and destroy work with normal compute auth / API keys
