VERDICT

ranking generation 3

solid 81/100 #81 of 104 in AI by measured score

What the score read on this service: status online, 100% uptime 24h (no 30d window yet), 296ms response p95, x402 compliance 11 of 13, $0 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 AI, 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 104 listings, this one among them. That set is wider than the 104 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.

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

compliance C (11/13): atomic price declared, EIP-712 domain parameters present on every EVM entry

11 of 13 x402 conformance checks pass; failing: atomic price declared, EIP-712 domain parameters present on every EVM entry. Full checklist below.

jump to compliance checklist

signability route not signable

At least one EVM route on this service returns its 402 without the EIP-712 domain parameters (extra.name and extra.version), so a standard x402 client cannot build the signature for that route.

Measured on the last 402 envelope captured from this service. It is a fact about the envelope, not a judgement on the service or its operator.

This is the only conformance check that caps the compliance grade, at C.

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/warppay402-mcp-gateway/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.
