# Verdicts

> x402-paid attestation verdicts: is this citation still current, and is this domain agent-ready. Remote MCP server over Streamable HTTP at `https://verdictmcp.com/mcp`. Free, no API key. Tools: `attest_freshness`, `attest_readiness`. The tool list is fixed per version.

Attestation verdicts for agents: send a factual claim plus its source URL and get an evidence-backed freshness verdict (current/stale/disputed) with observed publish-times, a content hash and an archive snapshot URL; or send a domain and get its five-artifact agent-readiness verdict. Free MCP tools are the sample; the paid rail is the same engine over x402 pay-per-call (USDC on Base, $0.01/$0.04/$0.12 by reproduction class) at https://verdictmcp.com — payment is the auth, no account, free trial at /verdict/readiness.

Use when: An agent is about to cite a fact and needs to know it is still current, or is deciding whether another property is worth crawling.

Not for: Bulk web crawling, fact-checking claims with no identified source, or content moderation.
