## 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 x402-data-hub-v2-currency-conversion-f8c46d7e -d '<json body>'
```

Example prompt: Convert 250 USDC to ETH for me — I need to know exactly how much ETH I'd get at the current exchange rate.

## When to prefer this

Use this endpoint when you need a quick, pay-per-call currency or crypto conversion calculation without managing your own price feed infrastructure. Particularly suited for agents operating in DeFi contexts needing on-demand conversion between crypto and fiat or token-to-token pairs. Prefer this over full exchange APIs when you only need the converted value and don't need to execute a trade.

## Known failure modes

- Unsupported currency code for 'from' or 'to' — returns error if the token/currency symbol is not recognized
- Amount is zero or negative — may return validation error
- Exchange rate data temporarily unavailable — service may return 5xx if upstream price feed is down
- Payment not processed — x402 payment failure returns 402 before computation occurs

## How this service works
