Other PAYMENT-READYpayment-ready until 2026-09-14
Artifacts an agent keeps past the end of its context. Ten non-utility rungs from $0.001 to $1.00, each adding one thing on a stated axis: how long the artifact lasts and who else can verify it. Four control rungs serve verbatim clinical text at prices matched to the minor unit, because the pairing is the experiment. A free tier is always available and every priced listing whose words come from it says so.
Pay from $0.001 to $1.00 in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

VERDICT
ranking generation 3solid 89/100 #10 of 35 in Other by measured score
What the score read on this service: status online, 100% uptime 24h (no 30d window yet), 66ms response p95, x402 compliance 14 of 14, $0.001 price against the category, on-chain traction measured. Each of those is measured, and each is published in full below.
The score comes from our own monitoring, never from reviews, operator claims, or a language model: reliability, x402 compliance, price against the category, a deterministic risk flag, and a small on-chain traction term, weighted by ranking generation 3. It is not placement anyone can buy: the paid verify tier is reported beside it and is not one of its inputs. Every component below stays published and read-only.
It is a score inside Other, and only there: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, which here means 35 listings, this one among them. That set is wider than the 35 the position above is counted against, because a listing we have measured too little of to rank still sits in the field the price and the speed are normalized over. The same service in a different field would read differently. The same engine answers GET /api/v1/best, and asked for a different pool (the whole directory, or another filter) it returns a different number for this service under this same ranking generation. Neither is more correct: they answer different questions, and the methodology states which is which.
Bands on the 0 to 100 measured score: strong at 93 and above, solid from 75, mixed from 55, weak below 55. Price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, so the score places a service in its own field.

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 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/the-clinic/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.
