x402 Payment Protocol

Use the npx awal@latest x402 commands to discover, inspect, and call paid API endpoints using the X402 payment protocol. Payments are made in USDC on Base.

Workflow

The typical x402 workflow is: Find a service - Search the bazaar or get details for a known endpoint Check requirements - Inspect price, method, and input schema Make the request - Call the endpoint with automatic USDC payment

Search the Bazaar

Find paid services by keyword using BM25 relevance search: npx awal@latest x402 bazaar search <query> [-k <n>] [--force-refresh] [--json] OptionDescription-k, --top <n>Number of results (default: 5)--force-refreshRe-fetch resource index from CDP API--jsonOutput as JSON Results are cached locally at ~/.config/awal/bazaar/ and auto-refresh after 12 hours.

List Bazaar Resources

Browse all available resources: awal x402 bazaar list [--network <network>] [--full] [--json] OptionDescription--network <name>Filter by network (base, base-sepolia)--fullShow complete details including schemas--jsonOutput as JSON

Discover Payment Requirements

Inspect an endpoint's x402 payment requirements without paying: awal x402 details <url> [--json] Auto-detects the correct HTTP method (GET, POST, PUT, DELETE, PATCH) by trying each until it gets a 402 response, then displays price, accepted payment schemes, network, and input/output schemas.

Make a Paid Request

Call an x402 endpoint with automatic USDC payment: awal x402 pay <url> [-X <method>] [-d <json>] [-q <params>] [-h <json>] [--max-amount <n>] [--json] OptionDescription-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--jsonOutput as JSON

Examples

# Search for weather-related paid APIs awal x402 bazaar search "weather" # Search with more results awal x402 bazaar search "sentiment analysis" -k 10 # Check what an endpoint costs awal x402 details https://example.com/api/weather # Make a GET request (auto-pays) awal x402 pay https://example.com/api/weather # Make a POST request with body awal x402 pay https://example.com/api/sentiment -X POST -d '{"text": "I love this product"}' # Limit max payment to $0.10 awal x402 pay https://example.com/api/data --max-amount 100000 # Browse all bazaar resources with full details awal x402 bazaar list --full

USDC Amounts

X402 uses USDC atomic units (6 decimals): Atomic UnitsUSD1000000$1.00100000$0.1050000$0.0510000$0.01

Prerequisites

Search/Details: No authentication needed Pay: Must be authenticated (awal auth login <email>) with sufficient USDC balance (awal balance)

Error Handling

"Not authenticated" - Run awal auth login <email> first "No X402 payment requirements found" - URL may not be an x402 endpoint "CDP API returned 429" - Rate limited; cached data will be used if available "Insufficient balance" - Fund wallet with USDC (awal balance to check)
