# Strale C2PA Inspect

> Strale C2PA Inspect is a paid API for AI agents from api.strale.io, paid per call via x402, $0.108/call, status unknown (last checked 2026-09-14).

Inspects an image URL for C2PA (Coalition for Content Provenance and Authenticity) manifests, returning provenance metadata and authenticity signals with an auditable cryptographic record.

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 strale-c2pa-inspect-c198575a -d '<json body>'
```

Example prompt: Can you check this image for C2PA content credentials and tell me if it has provenance data showing who created it or whether it was AI-generated? Here's the URL: https://example.com/photo.jpg

## When to prefer this

Use this endpoint when you need to verify the authenticity and provenance of an image according to the C2PA standard, especially for trust-and-safety workflows, newsroom fact-checking, AI-generated content detection, or any scenario where knowing the origin, creator, and editing history of an image matters. It is purpose-built for C2PA manifest extraction with an auditable cryptographic record, making it preferable to generic EXIF readers or metadata extractors that do not understand the C2PA trust hierarchy.

## Known failure modes

- Image URL is not publicly accessible or returns a non-200 status — endpoint cannot fetch the image
- Unsupported image format (e.g. GIF, BMP, SVG) — returns format error
- Image has no embedded C2PA manifest — returns empty or null manifest result
- URL resolves to a non-image resource — parsing error or format rejection
- Network timeout fetching large image files — request timeout error
- Malformed or corrupted C2PA manifest in the image — parsing failure with error details

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns extracted C2PA manifest data including signer identity, creation tool, timestamps, provenance assertions, AI-generation flags, and a cryptographic audit record with chain hashing for tamper-evidence. If no manifest is present, indicates the image lacks content credentials.
