Making Paid x402 Requests
Use the npx awal@latest x402 pay command to call paid API endpoints with automatic USDC payment on Base.
Confirm wallet is initialized and authed
npx awal@latest status
If the wallet is not authenticated, refer to the authenticate-wallet skill.
Command Syntax
npx awal@latest x402 pay <url> [-X <method>] [-d <json>] [-q <params>] [-h <json>] [--max-amount <n>] [--json]
Options
| Option | Description |
| ----------------------- | -------------------------------------------------- |
| -X, --method <method> | HTTP method (default: GET) |
| -d, --data <json> | Request body as JSON string |
| -q, --query <params> | Query parameters as JSON string |
| -h, --headers <json> | Custom HTTP headers as JSON string |
| --max-amount <amount> | Max payment in USDC atomic units (1000000 = $1.00) |
| --correlation-id <id> | Group related operations |
| --json | Output as JSON |
USDC Amounts
X402 uses USDC atomic units (6 decimals):
| Atomic Units | USD | | ------------ | ----- | | 1000000 | $1.00 | | 100000 | $0.10 | | 50000 | $0.05 | | 10000 | $0.01 |
IMPORTANT: Always single-quote amounts that use $ to prevent bash variable expansion (e.g. '$1.00' not $1.00).
Examples
# Make a GET request (auto-pays)
npx awal@latest x402 pay https://example.com/api/weather
# Make a POST request with body
npx awal@latest x402 pay https://example.com/api/sentiment -X POST -d '{"text": "I love this product"}'
# Limit max payment to $0.10
npx awal@latest x402 pay https://example.com/api/data --max-amount 100000
Prerequisites
- Must be authenticated (
npx awal@latest statusto check, seeauthenticate-walletskill) - Wallet must have sufficient USDC balance (
npx awal@latest balanceto check) - If you don't know the endpoint URL, use the
search-for-serviceskill to find services first
Error Handling
- "Not authenticated" - Run
awal auth login <email>first, or seeauthenticate-walletskill - "No X402 payment requirements found" - URL may not be an x402 endpoint; use
search-for-serviceto find valid endpoints - "Insufficient balance" - Fund wallet with USDC; see
