How this service works
Latin American government reference data for 22 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 JSON object containing the specific government reference value for the requested country and series, including the numeric or text value, the official source URL (e.g. central bank gazette), the last-confirmed date, and a staleness flag indicating whether the data may be outdated.
Example use cases
VAT rate lookup for invoice compliance
“I need to know the current VAT rate in Colombia so I can calculate the correct tax on our invoices — can you fetch the official cited figure from latamref with its source and last-confirmed date?”
Corporate tax benchmarking across LatAm
“What is Chile's current corporate income tax rate? Pull the certified government reference value with the official source URL so I can add it to our benchmarking report.”
Central bank policy rate for financial modeling
“Can you get me the current Banco de México overnight policy rate from latamref, including when it was last confirmed and where it's sourced from?”
Technical details
Endpoint
GEThttps://latamref.dev/v1/certified/%7Bcountry%7D/%7Bseries%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single authoritative, cited government reference data point for a specific Latin American country and series (e.g. exactly Mexico's VAT rate or Brazil's policy rate), and you need the official source URL and confirmation date for compliance or audit purposes. Prefer this over the country-brief endpoint when you only need one series for one country to minimize cost ($0.003 vs $0.01). Prefer over the cross-country compare endpoint when you only need one country.
Side effects
- Country not covered — endpoint returns refusal for unsupported countries
- Series not available for requested country — returns error indicating missing coverage
- Invalid country or series code — returns 400-style error
- Payment not received or insufficient — x402 payment required error
- Stale data — value returned with stale flag set true when source has not been re-confirmed recently
