Second Opinion

Verification

Adversarial verification for AI agents: an independent skeptic attempts to refute a claim before the agent acts on it, returning a structured verdict (refuted / supported / inconclusive) with calibrated confidence, findings, and citations. Three tiers: quick reasoning check ($0.03), single skeptic with live web research ($0.20), three-skeptic panel with majority verdict ($0.75). USDC via x402 on Algorand, Base, and Solana. No accounts, no API keys.

Pay from $0.03 to $0.75 per request in USDC on Base / Solana, settled onchain via the x402 protocol, no signup, no API key needed.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

OVER TIME

All charts share the 24h window selected here. Every series is also served as JSON at /api/v1/services/second-opinion-ms0hen6l-0/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
