## 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-kes-official-fx-rate-9b7cf0ca -d '<json body>'
```

Example prompt: What's the official USD to KES 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 a structured, single-pair USD-KES official exchange rate with provenance metadata (timestamp + source) for Kenya-specific use cases such as remittance calculations, invoice conversions, or compliance reporting. Prefer this over a multi-pair bulk endpoint when only the KES rate is needed and you want to minimize payload size and cost. Use the parallel/street-rate sibling endpoints if you need informal market rates from P2P order books.

## Known failure modes

- Rate data unavailable from upstream source — may return stale or null rate
- Invalid pair path returns 404 or error response
- Payment authorization failure via x402 protocol returns 402 before data is served
- Upstream Frankfurter API outage results in timeout or error

## How this service works

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

## Output

A JSON object containing the currency pair label (USD-KES), the official numeric exchange rate (e.g. 129.2 KES per 1 USD), the date the rate was recorded (ISO date string), and the name of the upstream data source (e.g. 'frankfurter').
