## Quick Start
1. Hit any agent endpoint: `GET https://api.hlprivateer.xyz/v1/agent/stream/snapshot`
2. Receive `402 Payment Required` with `PAYMENT-REQUIRED` header containing payment instructions
3. Decode the header (Base64 JSON) to get price, network, payTo address, and facilitator URL
4. Create and sign an x402 payment payload for the specified amount (USDC on Base)
5. Retry the same request with the `PAYMENT-SIGNATURE` header containing the signed payment (Base64 JSON)
6. Receive data in the `200` response plus `PAYMENT-RESPONSE` settlement header
## Base URLs
- REST API: `https://api.hlprivateer.xyz`

## How The Desk Works
HL Privateer runs autonomous agents on a single Hyperliquid account:
- **Strategist**: scans 50+ perp markets, generates long/short proposals with thesis and sizing
- **Research**: regime hypotheses, macro context, funding analysis, social sentiment
- **Risk**: explains risk posture (advisory only -- hard-gated by deterministic risk engine)
- **Execution**: suggests tactics, annotates slippage expectations
- **Ops**: monitors feeds, service health, circuit breakers (3s heartbeat)
- **Market Data**: detects stale feeds, regime shifts, funding divergences
- **Scribe**: produces audit narratives for each proposal cycle
All proposals pass through a deterministic risk engine (fail-closed) before execution. No agent can bypass risk limits. The human operator holds kill-switch authority.
## Runtime Modes
| Mode | Meaning |
|------|---------|
| `INIT` | Starting up, loading keys and config |
| `WARMUP` | Collecting initial market data window |
| `READY` | Flat, watching for opportunities |
| `IN_TRADE` | Active long/short positions |
| `REBALANCE` | Adjusting position weights for parity |
| `HALT` | Operator-initiated stop |
| `SAFE_MODE` | Automatic safety stop (dependency or data failure) |
## Error Responses
All errors follow a standard envelope:
```json
{
"error": {
"code": "RISK_DENY",
"message": "Proposal denied by max drawdown rule",
"requestId": "req_01J..."
}
}
```
Common error codes:
| Code | Meaning |
|------|---------|
| `PAYMENT_REQUIRED` | x402 payment needed (HTTP 402) |
| `UNAUTHORIZED` | Missing or invalid authentication |
| `FORBIDDEN` | Insufficient tier or capability |
| `RISK_DENY` | Risk engine denied the action |
| `RATE_LIMITED` | Too many requests |
| `INTERNAL_ERROR` | Server error |
