payment-ready until 2026-09-08
SEO and AI-visibility data agents buy per call. 17 GET endpoints: keyword research and metrics, on-page audits, AI-citation checks across ChatGPT, Claude, Gemini and Perplexity, rank and SERP checks, domain overview/keywords/history, and backlinks. $0.005-$0.30 per call in USDC on Solana mainnet via x402 v2 (exact scheme, PayAI facilitator). No account and no API key - the wallet is the identity. Any 4xx/5xx cancels the payment instead of settling it, so a failed call is never charged.
Pay from $0.005 to $0.30 per request in USDC on Solana, settled onchain via the x402 protocol, no signup, no API key needed.

VERDICT
ranking generation 3solid 87/100 #68 of 257 in Data by measured score
What the score read on this service: status online, 100% uptime 30d, 336ms response p95, x402 compliance 13 of 13, $0.005 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 Data, 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 257 listings, this one among them. That set is wider than the 257 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.

Other Data 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).

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/citable/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.
