USDC · per call · x402 on Base

What you get

Check a specific business claim against up to four public same-site pages and return supported, related-evidence, or unresolved with exact first-party quotes, source URLs, observation time, limitations, and claim-safety notes. Absence is reported as unresolved, not proof that a claim is false.

A conservative claim verdict with first-party citations and clear evidence boundaries.

Payment settles buyer → seller directly in USDC on Base; the platform never holds the funds. Every settlement emits a public, signed receipt. New here? Start at /SKILL.md.
