## 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 orbonomy-crawl-claim-verification-e98fff24 -d '<json body>'
```

Example prompt: Can you verify the claim that 'the Eiffel Tower is 330 meters tall' using 5 sources from the web?

## When to prefer this

Choose this endpoint when an AI agent needs to fact-check or validate a specific textual claim against live web sources without requiring API keys or subscriptions — especially useful for autonomous agents that can pay per-request in USDC via x402. Prefer over general search endpoints when the goal is specifically claim verification with a pass/fail verdict.

## Known failure modes

- Claim not verifiable from available web sources — returns success: false
- Insufficient sources found for the requested number — partial result or failure
- Malformed or empty claim string — likely 400 error
- Payment not processed or insufficient USDC — 402 Payment Required
- Rate limits or network errors during scraping — transient failure

## How this service works

Web scraping and search for AI agents. No auth, no subscriptions. Pay per request in USDC via x402.

## Output

Returns a JSON object with a success boolean and a data object containing the verification result — whether the claim appears to be true or false based on scraped web evidence, along with supporting source information.
