usaref — North American government reference data

Data PAYMENT-READY

payment-ready until 2026-09-21

North and Central American government reference data as clean, cited JSON: central-bank policy rates, VAT and sales tax, corporate and personal income tax, minimum wages, CPI inflation, official FX fixes and public holidays across 10 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. Includes sub-national public-holiday calendars for 10 US states and all 13 Canadian provinces and territories, each cited to that jurisdiction's own statute rather than inferred from a federal list. Paid per call in USDC on Base via x402 — no key, no signup. Public holidays are free. The United States is the free evaluation country.

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 3

solid 85/100 #100 of 302 in Data by measured score

What the score read on this service: status online, 100% uptime 24h (no 30d window yet), 728ms 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 302 listings, this one among them. That set is wider than the 302 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.

Canada layers three distinct regimes on top of it, so the rate a buyer actually pays depends on the place of supply: (1) HST provinces, where the federal 5% and a provincial component are collected as a single harmonised tax administered by the CRA under s. 165(2) — Ontario 13%, New Brunswick 15%, Newfoundland and Labrador 15%, Prince Edward Island 15%, and Nova Scotia 14% (Nova Scotia's provincial component was cut from 10% to 9% effective 1 April 2025, taking its HST from 15% to 14%); (2) GST + separate provincial retail sales tax (PST), levied and administered by the province, not the CRA — British Columbia PST 7%, Manitoba PST 7%, Saskatchewan PST 6%, and Quebec QST 9.975% (administered by Revenu Québec, and unlike a true PST the QST is a value-added tax); (3) GST only, at a flat 5% — Alberta, Northwest Territories, Nunavut and Yukon, which levy no sales tax of their own. A blended or population-weighted national figure would be an invention and is not served. Basic groceries, prescription drugs, medical devices and exports are zero-rated (0%) everywhere in Canada; financial services, most residential rent and most health/education services are exempt. Rate history: GST introduced at 7% on 1 January 1991, cut to 6% on 1 July 2006 and to 5% on 1 January 2008; the federal 5% has been unchanged for over 18 years. Note the temporary GST/HST holiday on certain goods that ran 14 December 2024 to 15 February 2025 — this was a targeted zero-rating measure, not a change to the 5% statutory rate, but it distorts CPI year-over-year comparisons for those months. canada.ca returns HTTP 403 to plain scripted fetchers (re-confirmed 2026-07-20); this page was read through a real browser session.",

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/usaref-north-american-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.
