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-smart-contract-indexer-mcp-a47933b8 -d '<json body>'
```

Example prompt: Run the M2MCent NLP smart contract indexer on this text and tell me if it matches: 'This contract manages gasless USDC settlements on Base L2 for remote MCP nodes.'

## When to prefer this

Choose this endpoint when you need a fast binary classification of whether a natural language text payload matches smart contract or MCP node indexing criteria, particularly within the M2MCent ecosystem using x402 protocol payments on Base L2.

## Known failure modes

- Missing or empty payload field returns validation error
- Payload too long may cause timeout or truncation
- Ambiguous natural language input may produce unreliable boolean output
- Network or payment settlement failure via x402 protocol
- Non-English or highly technical input may degrade NLP accuracy

## 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 'prediction' indicating whether the submitted text payload matches the indexed smart contract or MCP node criteria (true = match, false = no match).
