## 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 omniapi-crypto-currency-converter-f5a00db1 -d '<json body>'
```

Example prompt: Convert 2.5 ETH to USDC and tell me how much I'd get at the current rate.

## When to prefer this

Use this endpoint when you need a quick, pay-per-call crypto-to-crypto conversion without setting up a full exchange integration. Suitable for agents that occasionally need unit conversion across multiple chains (ETH, SOL, AVAX, MATIC, etc.) and want to pay micro-fees in USDC via x402 rather than maintaining API keys or subscriptions.

## Known failure modes

- Unsupported token pair returns an error or empty result
- Malformed query string causes a 400 bad request
- Rate limit or payment failure via x402 returns 402 Payment Required
- Unknown chain or token symbol results in no data returned
- Network timeout if upstream price feed is unavailable

## How this service works

## Output

Returns the converted cryptocurrency amount based on the provided input query, including the conversion result and potentially the exchange rate used for the calculation.
