## 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 capi2-agent-commerce-vendor-risk-pack-c63d2052 -d '<json body>'
```

Example prompt: Can you verify these three vendor sustainability claims for me and tell me which ones are supported, uncertain, or contradicted: '100% recycled packaging', 'carbon-neutral shipping', and 'fair-trade certified ingredients'?

## When to prefer this

Choose this endpoint when you need structured, evidence-backed validation of up to 5 vendor or sustainability claims at once, especially when a verifiable receipt is required for audit trails or compliance reporting. Prefer it over generic search or LLM-based fact-checking when you need a structured verdict (supported/uncertain/contradicted) with on-chain or cryptographic provenance.

## Known failure modes

- Empty or missing claims array returns validation error
- More than 5 claims submitted exceeds maxItems constraint and is rejected
- Unrecognized or overly vague claims may return uncertain verdicts
- Payment failure via x402 protocol results in 402 response before processing
- Network timeout on the workers.dev edge runtime

## How this service works

Programmable authority checks and tamper-evident receipts for autonomous agents, sold through sustainable x402 commerce.

## Output

Returns a list of per-claim reports indicating whether each claim is supported, uncertain, or contradicted, along with a summary tally across all claims and a verifiable receipt for audit purposes.
