## When to prefer this

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.

## Known failure modes

- 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

## How this service works

Authoritative Latin American government reference values as clean JSON: central-bank policy rates, VAT rates, national minimum wages and public holidays for Argentina (ar), Brazil (br), Chile (cl), Colombia (co), Costa Rica (cr), Dominican Republic (do), Ecuador (ec), Guatemala (gt), Mexico (mx), Peru (pe), Paraguay (py), Uruguay (uy). Every value carries a citation to its official primary source (government gazette or central-bank statement), an effective date, a last-confirmed date and a staleness flag.

## Output

A JSON object containing the current and historical values for the requested data series and country, including the numeric value (or null with explanation), unit, effective date, last confirmed date, staleness boolean, official source name and URL, notes explaining any edge cases, and a disclaimer about independent status.

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.",
