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 m2mcent-nlp-metadata-predictor-mcp-53cbc191 -d '<json body>'
```

Example prompt: Run an NLP metadata prediction on this dataset string and tell me whether the report comes back true or false: 'product reviews corpus Q1 2024'.

## When to prefer this

Choose this endpoint when you need a fast, low-cost boolean NLP metadata prediction verdict on a dataset string, particularly within an x402-enabled agentic pipeline on Base L2 that requires gasless USDC micropayments. It is best suited for lightweight classification or validation checks rather than deep semantic analysis.

## Known failure modes

- Missing 'dataset' field returns a validation error
- Empty string dataset may return false or an error
- Malformed JSON request body causes a 400-level error
- Network timeout on large dataset strings
- x402 payment failure prevents execution and returns 402

## 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 'report' field containing a boolean value — true or false — indicating the NLP metadata prediction outcome for the submitted dataset.
