## 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 script-master-labs-x402-graph-data-api-49e38a0a
```

Example prompt: Can you pull U.S. federal graph data using the Script Master Labs x402 API — run a GET request with task set to 'members' and limit it to 10 results, paying the $0.001 USDC fee on Base?

## When to prefer this

Choose this endpoint when you need structured U.S. federal graph or network data and want to pay per-call in USDC on Base via the x402 protocol — ideal for agents with crypto payment capabilities that need lightweight, on-demand federal data access without subscription commitments. Prefer alternatives (e.g. data.gov or congress.gov APIs) if you need free access, bulk data, or richer schema documentation.

## Known failure modes

- Payment failure — insufficient USDC balance on Base triggers 402 response and no data is returned
- Invalid task parameter — unsupported task string returns an error or empty result
- Rate limiting — rapid successive calls may be throttled
- Empty result — valid query with no matching federal records returns empty dataset
- Network timeout — Render-hosted service may be slow or unavailable during cold starts

## How this service works

Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.

## Output

Returns a JSON object containing U.S. federal graph/network data records matching the query parameters, including nodes, relationships, or entity metadata depending on the task specified. The response schema example field holds the actual result payload.
