# Proofivy Library Server – Apple Devices Content Fetch

> Proofivy Library Server – Apple Devices Content Fetch is a free API for AI agents from library.proofivy.com, callable via x402, Free, status unknown (last checked 2026-09-14).

Fetches article text for a specific Apple devices content item by its Proofivy CID, returning the content alongside a cryptographic commitment to the exact bytes delivered.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 proofivy-library-server-apple-devices-content-fetch-2c72ebfa
```

Example prompt: Can you fetch the Apple devices article with Proofivy CID bafkreiexample123 from the Proofivy library and give me the full text along with the CID so I can verify the content integrity?

## When to prefer this

Use this endpoint when you need to fetch article content from the Proofivy library specifically in the Apple devices category and require a cryptographic proof (CID) that the bytes returned are exactly what was committed — useful for integrity-sensitive retrieval, auditing, or when building applications that need verifiable content provenance.

## Known failure modes

- Invalid or malformed CID returns an error or 404 response
- CID does not correspond to an Apple devices article, returning not found
- Payment via x402 fails or is insufficient, blocking access
- Network timeout or library server unavailability
- CID exists but content has been removed or is no longer accessible

## How this service works

Content fetch API. Pay per request via x402 and receive the article text together with its Proofivy content-id (CID), a cryptographic commitment to the exact bytes returned.

## Output

Returns a JSON object containing the article text under the 'text' field, a 'status' field indicating success, and the 'proofivy_cid' — a cryptographic CID (e.g. bafkrei...) that commits to the exact bytes of the content returned, enabling integrity verification.
