## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability toolrail-latin-american-tax-unit-converter-uit-uvt-uma-a942fdaa
```

Example prompt: What's the current official UIT value in Peru, and how much is 3 UIT in Peruvian soles right now?

## When to prefer this

Use this endpoint when a law, contract, fine, tax threshold, or regulatory fee is expressed in UIT (Peru), UVT (Colombia), or UMA (Mexico) and you need to convert it to a local currency amount with official legal backing. Prefer this over manual lookup or general financial data APIs when you need the specific legal norm citation and exact validity period for compliance or legal documentation purposes.

## Known failure modes

- Unsupported unit type returns an error (only UIT, UVT, UMA are supported)
- Date outside the known validity windows may return no result or an error
- Missing required query parameters (unidad) causes a bad request response
- Non-numeric quantity value for cantidad may cause a parsing error

## How this service works

Annual tax units used to express fines, thresholds and fees in Latin America: UIT (Peru), UVT (Colombia) and UMA (Mexico). Official value for a date with its legal act and validity window, plus conversion of N units to local currency. Use when a law, fine, tax threshold or fee is stated in UIT, UVT or UMA and you need the amount in local currency.

## Output

Returns a JSON object with the country, unit type (UIT/UVT/UMA), official unit value in local currency, the legal norm/act that set it, the validity window (valid_from and valid_until dates), and the total local currency equivalent for the requested quantity of units.
