## 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 voidly-claim-verification-c6e5c847 -d '<json body>'
```

Example prompt: Can you check whether this claim is accurate: 'Twitter is being censored and throttled in Russia'? I want a verdict backed by real measured evidence plus any supporting incidents and a citation.

## When to prefer this

Choose this endpoint when you need a data-driven, evidence-backed verdict on a specific censorship claim rather than a general web search or opinion. It is uniquely suited for fact-checking censorship allegations with structured output (verdict + incidents + citation), particularly for journalists, researchers, digital rights advocates, or automated pipelines that need machine-readable censorship verdicts with provenance.

## Known failure modes

- Claim text too long (exceeds 500 characters) — request rejected with validation error
- Empty or missing claim field — returns 400 bad request
- Claim too vague or ambiguous — may return low-confidence or inconclusive verdict
- No measured evidence available for the claimed entity or region — verdict may be unconfirmed with no incidents
- Payment not attached or insufficient — x402 payment required error
- Service temporarily unavailable — 5xx error

## How this service works

## Output

A structured response containing a verdict (e.g. confirmed, unconfirmed, false) on the censorship claim, a list of related incidents observed through network measurements, and a citation pointing to the underlying evidence source.
