## 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 ni-biashara-usd-tzs-official-fx-rate-a11e2f1b -d '<json body>'
```

Example prompt: What's the official USD to Tanzanian shilling exchange rate right now? I need the rate, the date it was recorded, and where the data comes from.

## When to prefer this

Choose this endpoint when you need the official (central bank / ECB-sourced) USD-TZS rate for Tanzania, especially for compliance, invoicing, or audit purposes where an authoritative source citation is required. Prefer this over parallel/street-rate endpoints when the official rate is specifically needed. Use sibling endpoints for other African currency pairs or for parallel market rates.

## Known failure modes

- Rate data temporarily unavailable from upstream source — may return stale or error response
- Invalid or unsupported pair requested — endpoint is scoped to USD-TZS only
- Payment failure via x402 protocol results in 402 response before data is returned
- Network timeout if upstream Frankfurter/ECB feed is delayed

## How this service works

Single African FX pair vs USD (official rate, timestamp, source)

## Output

A JSON object containing the currency pair (e.g. 'USD-TZS'), the official exchange rate as a decimal number, the date the rate was recorded (ISO 8601 date string), and the named data source (e.g. 'frankfurter'). Returns a single rate snapshot, not a time series.
