## 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

```

Example prompt: Can you retrieve the private Pinata file with CID bafkreig64zjue3vnfqejtq2lmzdhgbbsin7gc7dxdebw3exy4ysjkoq62q for me — it costs $0.001 USDC to unlock?

## When to prefer this

Use this endpoint when you need to access a specific private file pinned on Pinata's IPFS infrastructure and are willing to pay a $0.001 USDC micropayment via the x402 protocol. Prefer this over public IPFS gateways when the file is private/gated. This is purpose-built for AI agents that can handle x402 payment flows for decentralized file retrieval.

## Known failure modes

- Payment insufficient or rejected — x402 payment header missing or USDC balance too low
- CID not found — the specified content identifier does not exist or has been unpinned
- Unauthorized access — payment processed but file access still denied
- Worker timeout — Cloudflare worker fails to respond within time limit
- Invalid CID format — malformed content identifier provided in the URL path
