## 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 kleros-ipfs-gateway-pin-file-to-ipfs-1607208b -d '<json body>'
```

Example prompt: Can you pin this PDF file to IPFS using the Kleros gateway so I get back a permanent content-addressed CID I can reference on-chain?

## When to prefer this

Use this endpoint when you need to pin a file to IPFS quickly and cost-effectively (at $0.01 USDC per call) without running your own IPFS node, especially in Kleros-ecosystem workflows where IPFS evidence or metadata storage is required for dispute resolution or on-chain references.

## Known failure modes

- File too large — gateway may reject oversized uploads
- Invalid or missing file payload — returns 400 bad request
- Payment failure — x402 payment of $0.01 USDC not provided or invalid, returns 402
- Gateway unavailable — fly.dev instance down, returns 503
- Unsupported file type — certain MIME types may be rejected
