## 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 scrapfly-claim-verification-api-5b98e6ae -d '<json body>'
```

Example prompt: Can you fact-check this claim for me using 5 sources: 'The Eiffel Tower is the tallest structure in France'?

## When to prefer this

Choose this endpoint when you need to programmatically verify a specific factual claim against multiple web sources, especially within an automated agent pipeline that handles x402 micropayments on Base chain. It is well-suited for fact-checking workflows where you want a structured true/false result with supporting data, rather than a raw web search or scrape.

## Known failure modes

- Empty or malformed claim string returns failure
- Invalid sources count (non-number) causes request rejection
- Network timeout if sources take too long to retrieve
- Ambiguous or too-short claim may return inconclusive result
- Rate limiting or payment failure via x402 protocol

## How this service works

69 endpoints for data, content generation, and web scraping. Pay per request via x402 on Base chain.

## Output

Returns a JSON object with a boolean 'success' field indicating whether the verification completed, plus a 'data' object containing the verification findings, source analysis, and determination about the claim's accuracy.
