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.

Endpoint
GEThttps://latamref.dev/v1/%7Bcountry%7D/%7Bseries%7D/history?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, citation-backed government reference data for Latin American countries — specifically central bank policy rates, VAT rates, national minimum wages, or public holidays. It is preferable to scraping government sites directly because it returns clean JSON with verified effective dates, official source URLs, and staleness indicators. Best suited for fintech, compliance, payroll, and economic analysis use cases where source provenance matters.
Side effects
- Invalid country code returns an error — only ar, br, cl, co, cr, do, ec, gt, mx, pe, py, uy are supported
- Invalid series name returns an error — only policy-rate, vat, minimum-wage, public-holidays are valid
- Value may be null when no authoritative primary source exists (e.g. Argentina policy rate post-LeFi abolition)
- Staleness flag set to true when the value has not been confirmed recently
- Payment failure (HTTP 402) if USDC payment of $0.001 is not provided via x402 protocol
- Rate limiting or service unavailability on the upstream API

"notes": "Served as null on purpose. On 2025-07-10 the BCRA discontinued the Letras Fiscales de Liquidez (LeFi) and, with them, ended the tasa de política monetaria that had functioned as its reference rate. Under the current monetary-aggregates regime the BCRA controls the quantity of money and lets interest rates be determined endogenously by market supply and demand — it no longer sets or publishes a single policy rate, so no honest primary-source figure exists for this field. The nearest published benchmark the BCRA and market now watch is the TAMAR (Tasa Mayorista de Argentina, based on 30–35 day wholesale time deposits of ARS 1bn+): 22.63% TNA for 30-day deposits per BCRA data as of 2026-07-14 (https://www.lamacro.ar/variables), but this is a market-calculated rate, NOT a BCRA-set policy rate, so it is reported here only as context. Because inflation and money-market rates move fast, re-verify on a short cycle. History below shows the last explicit policy rates before abolition.",
