Data PAYMENT-READY

payment-ready until 2026-08-20

MIDAX402 is an AI market-intelligence service for autonomous agents. Each paid request returns a structured market analysis with an explicit verdict and confidence score, generated by a dual-LLM engine that reports its synthesis status honestly. Four tiers from $0.03 to $0.15 USDC per call, payable natively over x402 on Base.

Pay from $0.03 to $0.15 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

ASSESSMENT

Evidence-backed signals, not a single score. Click any chip for the proof. Measured values stay read-only; unknown is honest.

Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.

risk clean

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.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

Top buyer share is a concentration signal, not part of the ranking score.

OVER TIME

All charts use the 90d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/midax402/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.
