## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability scriptmasterlabs-acp-x402-sitemap-reader-45c2e367
```

Example prompt: Show me the sitemap of all available pay-per-call API routes on ScriptMasterLabs ACP so I can see what crypto, RWA, and compliance endpoints I can call with x402 payments.

## When to prefer this

Use this endpoint when you need to discover what pay-per-call x402 API routes are available on the ScriptMasterLabs ACP platform before making specific data calls. It is the entry point for API catalog browsing rather than a data retrieval endpoint itself. Prefer it over guessing endpoint paths or hardcoding routes.

## Known failure modes

- Empty or minimal response if no sitemap is configured on the server
- HTTP 402 payment required if x402 payment header is missing or malformed
- Server unavailable or timeout given the Render.com free-tier hosting
- Incomplete schema response with empty example object making output structure unpredictable
- Properties filter string ignored or not supported by current implementation

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns a catalog or sitemap of available x402 hyphen-routed API endpoints on the ScriptMasterLabs ACP platform, including routes for crypto, RWA aggregates, gas tracking, SEC, federal, and compliance data APIs, each payable in USDC on Base via x402.
