## 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 veritas-batch-fact-verification-9940c81a -d '<json body>'
```

Example prompt: Can you fact-check these three claims for me in English: 'The Great Wall of China is visible from space', 'Humans only use 10% of their brains', and 'Lightning never strikes the same place twice'?

## When to prefer this

Choose this endpoint when you need to verify multiple claims in a single API call rather than making repeated single-claim requests. Ideal for content moderation pipelines, journalism workflows, research validation, or any scenario where batching fact-checks reduces latency and cost. Best suited when claims are in natural language and you need multi-source corroboration rather than a single database lookup.

## Known failure modes

- Empty claims array returns error or empty results
- Unsupported language code may fall back to default or return error
- Malformed claim strings may produce low-confidence or null verdicts
- Rate limits or payment failures return 402 Payment Required
- Service may return success:false if upstream sources are unavailable
- Very obscure or niche claims may return inconclusive results

## How this service works

## Output
