## 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 c2pa-provenance-manifest-inspector-0ffdd8d5 -d '<json body>'
```

Example prompt: Can you inspect the full C2PA provenance manifest for this JPEG I'm uploading — I want to see every manifest in the chain, who signed it, whether it's flagged as AI-generated, all the assertion labels, and any validation codes, not just a pass/fail verdict?

## When to prefer this

Choose this endpoint when you need the complete, raw C2PA provenance tree rather than a simple pass/fail authenticity verdict. It is ideal for forensic analysis, editorial audits, AI-origin investigations, or any workflow that needs to inspect individual manifest layers, assertion details, signer chains, or ingredient graphs. Prefer it over a verdict-only endpoint when the agent must reason about specific claims, edit sequences, or upstream asset provenance.

## Known failure modes

- Unsupported media type — format not in the accepted MIME/extension list returns an error; check GET /provenance/sources for supported types
- No C2PA metadata present — media file has no embedded manifests, returns empty or null manifest store
- Invalid base64 encoding — malformed media bytes cause a parsing failure
- File too large — oversized media may timeout or be rejected
- Corrupt manifest — partially written C2PA data may cause partial results or validation errors

## How this service works

Raw C2PA manifest-store dump for a media file, with no verdict wrapper. Returns every manifest in the provenance chain with its claim generator, signer, assertion labels, edit actions, AI-source flag, ingredient graph and the granular validation codes. For agents that want the full provenance tree rather than a go/no-go verdict. Heavy binary fields (thumbnails, hash blobs) are not echoed.

## Output

A structured dump of the full C2PA manifest-store for the submitted media file, containing every manifest in the provenance chain with: claim generator identity, signer information, all assertion labels, edit actions recorded, AI-source flag, ingredient graph showing upstream assets, and per-manifest granular validation status codes. Heavy binary fields like thumbnails and hash blobs are omitted.
