## 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-multi-currency-crypto-exchange-91f88287 -d '<json body>'
```

Example prompt: What's the current exchange rate from Bitcoin to USDC, and how much would 2.5 BTC be worth right now?

## When to prefer this

Use this endpoint when an agent needs real-time multi-currency cryptocurrency exchange rates or conversions and is already operating within the Meterly.Ai x402 pay-per-call ecosystem using USDC on Base Mainnet. Prefer this over alternatives when micropayment-based access without subscription is desired.

## Known failure modes

- Missing required 'query' field returns validation error
- Invalid or unsupported currency pair returns empty or error result
- Payment failure via x402 protocol prevents API access
- Malformed query string results in unexpected or empty response
- Rate limiting or upstream API unavailability returns 5xx error
