# 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:

1. **Find a service** - Search the bazaar or get details for a known endpoint
2. **Check requirements** - Inspect price, method, and input schema
3. **Make the request** - Call the endpoint with automatic USDC payment

## Commands

### Search the Bazaar

Find paid services by keyword using BM25 relevance search:

```bash
npx awal@latest x402 bazaar search <query> [-k <n>] [--force-refresh] [--json]
```

| Option            | Description                          |
| ----------------- | ------------------------------------ |
| `-k, --top <n>`   | Number of results (default: 5)       |
| `--force-refresh` | Re-fetch resource index from CDP API |
| `--json`          | Output as JSON                       |

Results are cached locally at `~/.config/awal/bazaar/` and auto-refresh after 12 hours.

### List Bazaar Resources

Browse all available resources:

```bash
awal x402 bazaar list [--network <network>] [--full] [--json]
```

| Option             | Description                             |
| ------------------ | --------------------------------------- |
| `--network <name>` | Filter by network (base, base-sepolia)  |
| `--full`           | Show complete details including schemas |
| `--json`           | Output as JSON                          |

### Discover Payment Requirements

Inspect an endpoint's x402 payment requirements without paying:

```bash
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:

```bash
awal x402 pay <url> [-X <method>] [-d <json>] [-q <params>] [-h <json>] [--max-am...
