Other PAYMENT-READYpayment-ready until 2026-10-11
29 pay-per-call endpoints on Base USDC (x402 v2, exact scheme), keyless, no signup. Two decision reports: agent-integration-readiness (five measured checks give a ready / ready_with_caveats / not_ready verdict) and integration-remediation-plan (same probes plus the ordered per-blocker repair list and an effort note). The remaining 27 are low-cost primitives: crypto and market data, Base L2 gas, Hacker News and entity sentiment, npm and tech-stack metadata, subdomains, and API-operations checks (CORS preflight, error shape, contract drift, deprecation, pagination Link headers, security.txt, cache/CDN policy, AI crawler and robots policy, llms.txt discovery surface). $0.002-$0.005 per primitive, $0.019 and $0.10 per decision report. All endpoints answer HTTP 402 with a valid bazaar extension and are indexed in the facilitator discovery catalog.
Pay from $0.002 to $0.10 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

VERDICT
ranking generation 3solid 88/100 #7 of 46 in Other by measured score
What the score read on this service: status online, 100% uptime, latest daily rollup (no 30d window yet), 68ms response p95, x402 compliance 14 of 14, $0.002 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 46 listings, this one among them. That set is wider than the 46 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.
ALTERNATIVES IN OTHER
Other Other services in this directory, ordered by the same measured score. The figures are ours: 30-day uptime from our own probes, 30-day settlement volume read on-chain (a conservative undercount, and null where we cannot measure it, never a zero).

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 part of the ranking score: a higher share lowers the traction part of the score, by up to half when one address holds all 30d volume.

] 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-data-tools/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.
