Satoshi API is Bitcoin fee intelligence for AI agents. It gives wallets, bots, and agent workflows send-now-or-wait timing guidance, next-block fee pressure, transaction context, and fee-estimator accuracy through x402 pay-per-call endpoints.
Pay from $0.005 to $0.01 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

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.

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

] OVER TIME
All charts share the 7d window selected here. Every series is also served as JSON at /api/v1/services/satoshi-api/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.
