## 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 m2mcent-web3-metadata-extractor-mcp-dfd8e223 -d '<json body>'
```

Example prompt: Can you check this image for web3 metadata and tell me if it has any — here's the image: [base64 or URL string]?

## When to prefer this

Use this endpoint when you need a lightweight boolean check on whether an image contains web3 or blockchain-related metadata, particularly in workflows that require low-latency yes/no signals before more expensive downstream processing. Prefer it over full NFT indexers or blockchain explorers when you only need image-level metadata presence, not on-chain state.

## Known failure modes

- Missing or invalid 'image' field returns a validation error
- Non-image or corrupt input may yield false negatives or processing errors
- Ambiguous image encoding (raw bytes vs base64 vs URL) may cause parsing failures
- Payment failure via x402 protocol results in HTTP 402 and no execution
- Service unavailability due to node routing issues in the MCP network

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a JSON object with a single boolean field 'report' — true if web3 metadata was found or validated in the image, false otherwise. No additional detail or extracted fields are provided beyond this boolean signal.
