# x402 Agent Payments 💧
Unified payment orchestration for AI agents. Four payment rails, one skill.
| Rail | What It Does | Env Var |
|------|-------------|---------|
| **Stripe** | Accept fiat — cards, invoices, subscriptions | `STRIPE_SECRET_KEY` |
| **Coinbase Commerce** | Accept crypto — BTC, ETH, USDC checkout | `COINBASE_COMMERCE_API_KEY` |
| **Coinbase CDP** | Send crypto — wallets, single transfers | `CDP_API_KEY` |
| **Spraay x402** | Batch send — payroll, multi-recipient, invoices | `SPRAAY_GATEWAY_URL` |
All requests go exclusively to the declared API endpoints for each provider.
No data is sent to any other external services. The skill works with any
combination of rails — set only the env vars you need.
## Important Warnings
**All payment operations involve real funds.** Whether fiat or crypto, every
transaction in this skill moves real money. The agent must always confirm
the following with the user before executing any payment:
- Payment amount and currency are correct
- Recipient (address, email, or account) is intended
- The user understands any associated fees
- For crypto: blockchain transactions are irreversible once confirmed
- For Stripe: card charges are real and will appear on statements
- For Commerce: charges expire after 60 minutes if unpaid
**Never execute payments without explicit user confirmation.**
## Choosing the Right Rail
| Use Case | Rail |
|----------|------|
| Charge a customer in USD | Stripe |
| Create an invoice (fiat) | Stripe |
| Recurring subscription | Stripe |
| Accept BTC/ETH/USDC from a customer | Coinbase Commerce |
| Create an agent crypto wallet | Coinbase CDP |
| Send crypto to one address | Coinbase CDP |
| Pay 10-1000 people at once | Spraay x402 |
| Monthly payroll in USDC | Spraay x402 |
| Invoice a client in crypto | Spraay x402 |
## Rail 1: Stripe — Accept Fiat Payments
Accept credit card payments, create invoices, manage subscriptions.
Requires `STRIPE_SECRET_KEY`.
### Create Checkout Session
**Confirm the product, price, and currency with the user first.**
```bash
curl -X POST "https://api.stripe.com/v1/checkout/sessions" \
-u "$STRIPE_SECRET_KEY:" \
-d "mode=payment" \
-d "success_url=https://example.com/success" \
-d "cancel_url=https://example.com/cancel" \
-d "line_items[0][price_data][currency]=usd" \
-d "line_items[0][price_data][unit_amount]=5000" \
-d "line_items[0][price_data][product_data][name]=Service Payment" \
-d "line_items[0][quantity]=1"
```
Returns a checkout URL to share with the customer.
### Create Payment Intent
```bash
curl -X POST "https://api.stripe.com/v1/payment_intents" \
-u "$STRIPE_SECRET_KEY:" \
-d "amount=5000" \
-d "currency=usd" \
-d "payment_method_types[]=card"
```
### Create Invoice
**Confirm invoice details with the user first.**
```bash
curl -X POST "https://api.stripe.com/v1/invoiceitems" \
-u "$STRIPE_SECRET_KEY:" \
-d "customer=cus_..." \
-d "amount=5000" \
-d "currency=usd" \
-d "description=Consulting — March 2026"
```
### Create Subscription
```bash
curl -X POST "https://api.stripe.com/v1/subscriptions" \
-u "$STRIPE_SECRET_KEY:" \
-d "customer=cus_..." \
-d "items[0][price]=price_..."
```
### Check Payment Status
```bash
curl "https://api.stripe.com/v1/payment_intents/pi_..." \
-u "$STRIPE_SECRET_KEY:"
```
### Refund a Payment
**Confirm refund with the user first.**
```bash
curl -X POST "https://api.stripe.com/v1/refunds" \
-u "$STRIPE_SECRET_KEY:" \
-d "payment_intent=pi_..."
```
## Rail 2: Coinbase Commerce — Accept Crypto
Accept cryptocurrency payments from customers. They pay in BTC, ETH, USDC,
or other supported coins via a hosted checkout page. Funds settle to your
Coinbase account. Requires `COINBASE_COMMERCE_API_KEY`.
### Create a Charge
**Confirm the amount and currency with the user first.**
```bash
curl -X POST "https://api.commerce.coinbase.com/charges" \
-H "Content-Type: application/json" \
-H "X-CC-Api-Key: $COINBASE_COMMERCE_API_KEY" \
-d '{
"name": "Service Payment",
"description": "Payment for consulting services",
"pricing_type": "fixed_price",
"local_price": {
"amount": "100.00",
"currency": "USD"
}
}'
```
Returns `hosted_url` (Coinbase checkout page to share with customer) and
`expires_at` (charges expire after 60 minutes).
### Check Charge Status
```bash
curl "https://api.commerce.coinbase.com/charges/CHARGE_ID" \
-H "X-CC-Api-Key: $COINBASE_COMMERCE_API_KEY"
```
Status flow: NEW → PENDING → CONFIRMED / FAILED / EXPIRED
### Cancel a Charge
```bash
curl -X POST "https://api.commerce.coinbase.com/charges/CHARGE_ID/cancel" \
-H "X-CC-Api-Key: $COINBASE_COMMERCE_API_KEY"
```
## Rail 3: Coinbase CDP — Crypto Wallets & Transfers
Create wallets and send crypto. For agent-managed funds and single transfers.
Requires `CDP_API_KEY`.
### Create Wallet
```bash
curl -X POST "https://api.developer.coinbase.com/platform/v1/wallets" \
-H "Authorization: Bearer $CDP_API_KEY" \
-H "Content-Type: application/json" \
-d '{"network": "base"}'
```
### Send Transfer
**Confirm recipient, amount, and token with the user first.**
```bash
curl -X POST "https://api.developer.coinbase.com/platform/v1/wallets/WALLET_ID/transfers" \
-H "Authorization: Bearer $CDP_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"destination": "0xRecipient...",
"amount": "100",
"asset": "usdc",
"network": "base"
}'
```
### Check Balance
```bash
curl "https://api.developer.coinbase.com/platform/v1/wallets/WALLET_ID/balances" \
-H "Authorization: Bearer $CDP_API_KEY"
```
## Rail 4: Spraay x402 — Batch Payments & Payroll
Pay multiple recipients in one transaction. 60-80% gas savings vs individual
transfers. Pay-per-call via x402 micropayments, no API key needed.
Uses `SPRAAY_GATEWAY_URL`.
### Batch Payment
**Confirm all recipients, amounts, token, and chain with the user first.**
```bash
curl -X POST "$SPRAAY_GATEWAY_URL/api/batch-payment" \
-H "Content-Type: application/json" \
-d '{
"recipients": [
{"address": "alice.eth", "amount": "3000"},
{"address": "bob.base", "amount": "2500"},
{"address": "0xCCC...999", "amount": "4000"}
],
"token": "USDC",
"chain": "base",
"memo": "March 2026 payroll"
}'
```
If you receive HTTP 402, pay the micropayment and retry with the
`X-PAYMENT` proof header.
### Create Invoice (Crypto)
```bash
curl -X POST "$SPRAAY_GATEWAY_URL/api/create-invoice" \
-H "Content-Type: application/json" \
-d '{
"recipient": "0xABC...123",
"amount": "500",
"token": "USDC",
"chain": "base",
"memo": "March consulting"
}'
```
### Token Price (Free)
```bash
curl "$SPRAAY_GATEWAY_URL/api/price?symbol=ETH"
```
### Resolve ENS / Basename (Free)
```bash
curl "$SPRAAY_GATEWAY_URL/api/resolve?name=vitalik.eth"
```
Supported chains: Base, Ethereum, Arbitrum, Polygon, BNB Chain, Avalanche,
Solana, Unichain, Plasma, BOB.
## Free Endpoints
No payment or API key required:
- `GET $SPRAAY_GATEWAY_URL/api/price?symbol=ETH` — Token prices
- `GET $SPRAAY_GATEWAY_URL/api/resolve?name=vitalik.eth` — Name resolution
- `GET $SPRAAY_GATEWAY_URL/api/health` — Gateway health check
- `GET $SPRAAY_GATEWAY_URL/api/chains` — Supported chains
## Error Handling
- `402` — x402 payment required. Follow response body instructions.
- `400` — Bad request. Check parameters.
- `401` — Missing or invalid API key (Stripe, Commerce, or CDP).
- `404` — Endpoint not found.
- `500` — Server error. Retry after a moment.
## Tips
- Always confirm with the user before executing any payment.
- Use Stripe to accept fiat from customers.
- Use Commerce to accept crypto from customers.
- Use CDP to create wallets and send single transfers.
- Use Spraay for batch operations — payroll, airdrops, multi-recipient.
- Not all env vars are required — set only the rails you need.
- Check `/api/price` to show USD equivalents for crypto payments.
