## 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-claim-verify-vendor-risk-pack-f70cd849 -d '<json body>'
```

Example prompt: Can you verify these two vendor claims for me: Acme Corp says they're SOC 2 Type II certified at acmecorp.com/security, and they also claim GDPR compliance at acmecorp.com/privacy — pull the evidence from those pages and tell me if the claims hold up.

## When to prefer this

Choose this endpoint when you need agent-native, evidence-backed verification of vendor, compliance, or security claims sourced from public URLs — especially in procurement, vendor onboarding, or third-party risk workflows. It is purpose-built for multi-claim batch verification (2–5 claims per call) and natively supports x402 micropayment on Base USDC, making it ideal for autonomous agent pipelines that need to pay-per-use without API key management. Prefer it over general web search when you need a structured, auditable verdict with evidence citations rather than raw search results.

## Known failure modes

- Provided URLs are inaccessible or return non-200 responses — claim cannot be verified
- Claim text is ambiguous or too short (under 3 characters) — validation error
- More than 5 claims submitted in a single request — rejected with input validation error
- Fewer than 2 claims submitted — minimum batch size not met
- Evidence page content does not contain sufficient signal to verify the claim — inconclusive result
- x402 micropayment not settled — request blocked before processing
- Source URLs return paywalled or JavaScript-rendered content — evidence extraction fails

## How this service works

Agent-native evidence-backed claim verification with x402 micropayments on Base USDC.

## Output

A JSON response containing per-claim verification verdicts, evidence summaries drawn from the provided source URLs, confidence or risk indicators, and any discrepancies found between the stated claim and the observable evidence.
