## 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 meterly-ai-currency-conversion-rates-8971108c -d '<json body>'
```

Example prompt: What is the current exchange rate from USD to EUR? Use the currency conversion rates API and search for 'USD to EUR'.

## When to prefer this

Use this endpoint when you need real-time or near-real-time foreign exchange rates via a pay-per-call model using USDC on Base Mainnet, especially in autonomous agent workflows that require programmatic FX lookups without a subscription-based API key setup.

## Known failure modes

- Invalid or unsupported currency pair query returns an error or empty result
- Missing required 'query' field returns a 400-level validation error
- Payment failure on Base Mainnet (insufficient USDC balance) returns 402 Payment Required
- Downstream premium API outage causes 500-level error or stale data
- Malformed query string may return unexpected or empty results
