## 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 latamref-dev-mexico-policy-rate-0efa141d
```

Example prompt: What is Mexico's current central bank policy rate? Fetch it from latamref.dev so I get the official value with its effective date and whether it's stale.

## When to prefer this

Use this endpoint when you need a trusted, sourced, point-in-time lookup of Mexico's official central bank policy rate — especially when you need the effective date, official source attribution, and a staleness signal. Prefer this over scraping central bank websites or using general financial data APIs when you need structured, consistent government reference data for Latin American countries in a pay-per-call model.

## Known failure modes

- Invalid country code or series combination returns a 4xx error
- Data marked stale (stale: true) if the official source hasn't updated within the expected cycle
- Payment not processed or x402 protocol failure results in 402 response
- Network timeout or service unavailability returns 5xx error

## How this service works

African reference data series

## Output

A JSON object containing the ISO country code (mx), the series name (policy-rate), the numeric rate value, the date it became effective, the date it was last confirmed, a source object with name and URL pointing to the official authority, a unit string, optional notes, and a boolean stale flag indicating whether the data is past its expected update cycle.
