## How to call it through Zero

```sh
zero fetch --capability proofivy-apple-device-content-library-e202cf42
```

Example prompt: Can you fetch the content from Proofivy with CID bafybeiabc123xyz456def789 that was posted from an Apple device?

## When to prefer this

Use this endpoint when you have a specific Proofivy CID for Apple device-posted content and need to retrieve its text. It is the canonical retrieval mechanism for the Proofivy library for Apple device content, with per-request micropayment billing at $0.01 USDC via x402. Prefer this when you need verifiable, CID-addressable content provenance tied to Apple devices.

## Known failure modes

- Invalid or non-existent CID returns an error status
- Content not found for the given CID returns a 404-equivalent response
- Malformed CID path parameter may cause a bad request error
- Payment failure via x402 protocol prevents content delivery
