## 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 fx-concept-oracle-c1dbecdf
```

Example prompt: Can you pull up the conceptual exchange rate metadata between the United States and Japan — I just need the currency concept info, no live rates required.

## When to prefer this

Use this endpoint when an AI agent needs conceptual or metadata-level currency information for a country pair without needing live exchange rates or holding external FX API keys. Ideal for lightweight currency context lookups in pipelines where real-time pricing is not required.

## Known failure modes

- Missing required countryA or countryB query parameters — returns 400 Bad Request
- Unrecognized country code or name — may return empty or null metadata
- Payment not processed — returns 402 Payment Required
- Service unavailable — returns 503 with no data
