ASR audio services: transcribe a podcast feed (RSS) or any direct audio URL into a clean timestamped transcript, optionally with an AI summary (thesis, key points, verbatim quotes). Two modes: synthesis (transcript + summary, from $0.10/30-min block) and transcript (transcript only, from $0.06/30-min block). Exact USDC price quoted in the 402 challenge; pay per job on Base.
Pay from $0.30 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

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 30d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/x402-shop-asr-audio-services/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.
