## 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-proptech-carbon-credit-indexer-mcp-node-25dd943b -d '<json body>'
```

Example prompt: Index this property audio clip through the proptech carbon credit indexer — here is the audio data string — and give me back the result hash.

## When to prefer this

Use this endpoint when you specifically need to process audio data through a proptech carbon credit indexing pipeline on the M2MCent monetized MCP network and require a hash-based result via x402 micropayment settlement.

## Known failure modes

- Missing or malformed 'audio' field returns validation error
- Invalid audio string format may produce unexpected boolean hash output
- Payment failure via x402 protocol blocks execution
- Network timeout on the remote MCP node
- Ambiguous boolean hash output provides limited actionable information

## 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 containing a 'hash' field typed as boolean, indicating the result of the carbon credit indexing operation.
