## 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-agent-score-lookup-19988c06
```

Example prompt: What's the agent score for agent ID 'agent-abc-12345'? I want to check its trust and reputation rating using the federal data lookup.

## When to prefer this

Use this endpoint when you need a pay-per-call, U.S.-federal-data-backed trust or reputation score for a specific AI agent ID, especially in workflows requiring agent vetting, compliance checks, or risk assessment settled on-chain via x402 on Base.

## Known failure modes

- Missing required agent_id parameter returns a 400 or validation error
- Payment not completed or insufficient USDC balance results in a 402 Payment Required response
- Invalid or unknown agent_id may return a null score or not-found error
- Service unavailability on the Render-hosted instance returns a 503
- Malformed action parameter may be ignored or trigger an error

## 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 numeric trust/reputation score and associated data for the provided agent ID, derived from U.S. federal data sources and delivered after a $0.20 USDC payment via x402 on Base.
