## 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 superoracle-fact-check-d97e59d8 -d '<json body>'
```

Example prompt: Can you fact-check these claims for me — 'Bitcoin is above $100k', 'Apple is the most valuable company', and 'The Fed raised rates last month' — and tell me which ones are currently true?

## When to prefer this

Choose this endpoint when you need real-time fact verification of textual claims, particularly market, financial, or current-events assertions, and require a per-claim verdict rather than a general web search. Ideal for AI pipelines that need to ground agent outputs in verified current truth before acting or publishing.

## Known failure modes

- Empty or missing input string returns validation error
- Input exceeding 8000 characters may be rejected
- Ambiguous or unparseable claims may receive uncertain verdicts
- Payment failure on Base network results in 402 response
- Stale or rapidly changing data may produce outdated verdicts
- Service unavailability returns 5xx error

## How this service works

Data and market intelligence. Feeds other Supers with what’s true right now.

## Output

Returns a job ID, a fact-check output with verdicts on each submitted claim assessed against current market and data intelligence, and a payment receipt including the blockchain transaction hash, amount paid, and network used.
