How this service works
North American government reference data for 10 countries as cited JSON: central-bank policy rates, VAT/GST and VAT registration thresholds, CPI, corporate, personal and withholding tax, social contributions, minimum wages, statutory interest, official FX rates, filing deadlines and public holidays (coverage varies by country). Every value carries its official source URL and last-confirmed date. Single facts $0.003; country brief (every series for one country) $0.01; cross-country compare (one series, up to 10 countries) $0.02; tax-ID and VAT-number checks $0.003; computed answers (VAT, income tax, working days, minimum-wage check) $0.01-$0.02. Pay per call in USDC on Base via x402 or MPP, no signup, or by card with credit packs or monthly plans on one key valid across all 7 regional services. Free tier: GET /catalog, plus a free email key with 50 answer calls a day, commercial use allowed. Finished answers, one cited dossier per call (supported countries vary per job; others are refused free): cost this hire (wage-floor verdict, contributions, employer cost) $0.50; charge this sale (which VAT applies, net/VAT/gross) $0.50; charge this sale certified (plus a signed VAT-rate extract) $0.75; invoice due date and statutory late interest $0.40; country evidence pack (brief plus signed extracts) $0.25; hire compare $0.75 for 2 countries, $1.00 for 3-5; next filings (VAT, PAYE, corporate-tax due dates rolled for holidays) $0.35. Free trial: 3 computed-answer calls per day per IP on POST /v1/answers/* with header X-Free-Trial: 1 (without it, the normal x402 402; once used up, the 402 carries free_trial_resets_at). MCP answer tools use the trial automatically when no api_key is passed. Every series of the evaluation country is free. Card credit (same per-call price as x402): /pricing.
Output
A single JSON object containing every available government reference series for the requested country — including central bank policy rate, VAT/GST rate and registration threshold, CPI, corporate/personal/withholding tax rates, social contributions, minimum wage, statutory interest, official FX rates, filing deadlines, and public holidays. Each value includes the official government source URL and a last-confirmed date. Unsupported series for a given country are omitted or flagged.
Example use cases
Tax compliance overview for market entry
“We're expanding into Mexico — can you pull the full government reference brief for Mexico so I can see the corporate tax rate, VAT rate, social contributions, and minimum wage all in one place with official sources?”
Comparing statutory rates before investment
“I'm evaluating whether to incorporate in Canada or the US — can you get me the complete official reference dossier for each country, including the central bank policy rate, corporate tax, withholding tax, and VAT registration thresholds?”
Regulatory briefing for a payroll system
“We're building payroll for employees in Costa Rica — give me the full country brief including minimum wage, social contributions, personal income tax rates, and filing deadlines with their official source URLs so I can verify compliance.”
Technical details
Endpoint
GEThttps://usaref.dev/v1/brief/%7Bcountry%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a complete picture of all government reference data for a single North American country in one call, rather than fetching individual series separately. It is ideal for compliance briefings, market-entry research, payroll configuration, or investment due diligence where you want every official rate and threshold with citations. Prefer the per-series endpoints if you only need one specific metric and want to minimise cost, or the cross-country compare endpoint if you need one metric across multiple countries.
Side effects
- Country not covered — endpoint returns an error or partial response if the requested country is outside the supported 10-country North American scope
- Stale data warning — individual fields may carry a stale flag if the source has not been re-confirmed recently
- Invalid country identifier — malformed or unrecognised country code returns a 400-level error
- Payment failure — x402/MPP payment not completed results in a 402 response blocking data delivery
- Network timeout — upstream government source checks may occasionally delay or fail
