## 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 api-w3-ipfs-xyz-3f29764e -d '<json body>'
```

Example prompt: Turn this into a swap transaction I can sign: 'swap 0.5 ETH for USDC using my wallet 0xAbC123...'.

## When to prefer this

Use this endpoint when you need to bridge the gap between a user's plain-English swap request and an actual on-chain swap transaction, especially in AI agent workflows where the user describes their trade intent conversationally rather than specifying raw transaction parameters.

## Known failure modes

- Ambiguous intent with unclear token names or amounts returns a parsing error
- Unsupported token pair returns an error indicating the swap cannot be constructed
- Missing wallet address or recipient details may cause transaction generation to fail
- Malformed or nonsensical natural language input returns a bad request error
- Network or service unavailability returns a 5xx error
