## 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 latam-datos-api-mexico-fx-rate-usd-mxn-daf32f63
```

Example prompt: What's the current USD to Mexican peso exchange rate? I need the live USD/MXN rate right now for a payment calculation.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-query USD/MXN spot rate without a subscription, particularly in agentic workflows that already use the x402/USDC micropayment protocol on Base. It is best for one-off lookups or low-frequency monitoring where a subscription FX API would be overkill. If you need other LatAm currencies or additional data (inflation, central bank rates), other sibling endpoints on the same host cover those use cases.

## Known failure modes

- Service unavailable on Render.com free tier (cold start latency or downtime)
- Payment failure via x402 protocol (insufficient USDC balance or misconfigured wallet)
- Stale or cached rate if upstream data source is delayed
- HTTP 402 returned if payment not processed before data is served
- Network timeout on slow connections to Render hosting

## How this service works

## Output

Returns a JSON object with the currency pair label (e.g. 'USD/MXN') and the current exchange rate as a decimal number (e.g. {"par":"USD/MXN","tasa":17.48}), representing how many Mexican pesos one US dollar buys at the time of the query.
