# Voidly x402 Censorship Evidence API

> Voidly x402 Censorship Evidence API is a paid API for AI agents from x402.voidly.ai, paid per call via x402, $0.02/call, status unknown (last checked 2026-11-01).

Returns pay-per-call structured evidence reports on internet censorship incidents, sourced from measurement data providers like OONI, with deduplication and audit metadata.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-x402-censorship-evidence-api-23cdb3f7 -d '<json body>'
```

Example prompt: Pull the Voidly censorship evidence report for incident IR-2026-9999 — I need the full chronological measurement timeline, source summary, and a citable reference I can use in a research report.

## When to prefer this

Choose this endpoint when you need structured, citable, measurement-backed evidence for a specific internet censorship or network disruption incident, particularly when OONI data is relevant and you need deduplication audit trails. Prefer this over general web search when you need machine-readable, versioned incident reports with formal citations. Best suited for researchers, journalists, NGOs, or compliance workflows that require traceable evidence provenance rather than raw news coverage.

## Known failure modes

- Payment not received or invalid x402 USDC payment on Base (eip155:8453) — 402 Payment Required returned
- Incident ID not found — 404 or empty result
- Malformed POST body or missing required parameters — 400 Bad Request
- Data source (e.g. OONI) has no measurements for the requested incident — empty timeline returned with truncated:false
- Network timeout or upstream data provider unavailability — 503 or timeout error

## How this service works

Pay-per-call internet-censorship evidence. x402 v2 exact scheme, USDC on eip155:8453. Runtime 402 terms are authoritative.

## Output

A structured JSON evidence report including: incident metadata (ID, title, country, status, revision), a chronological measurement timeline with source attribution (e.g. OONI), deduplication audit (raw rows, deduplicated events, source counts), a free report URL with a ready-to-use citation string, report generation timestamp, and a list of limitations to disclose when citing the evidence.
