payment-ready until 2026-09-13
European government reference data as clean, cited JSON: ECB and Bank of England policy rates, VAT with reduced and zero bands, corporate and personal income tax, minimum wages, CPI inflation, statutory late-payment interest, official central-bank FX fixes and public holidays across 35 countries. Every value returns with the official source URL it was verified against, the date it took effect and the date we last checked it, so an answer can be audited rather than trusted. Each series also declares how it was obtained — GET /catalog?confidence=primary returns only values with no recorded verification limitation. Out-of-scope questions are refused free, with an explanation, rather than guessed. Also served: sub-national holiday calendars for Germany's 16 Länder and the four UK nations, point-in-time reads via ?as_at=YYYY-MM-DD, and settlement-date conventions including the enacted EU T+1 transition from 11 October 2027. Paid per call in USDC on Base via x402 — no key, no signup. Public holidays are free.
Pay from $0.005 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

VERDICT
ranking generation 3solid 84/100 #120 of 265 in Data by measured score
What the score read on this service: status online, 99.6% uptime 30d, 1262ms response p95, x402 compliance 14 of 14, $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 265 listings, this one among them. That set is wider than the 265 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 DATA
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).

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/euroref-european-government-reference-data/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.
Median across 2 endpoints. Use the selector to isolate one.
