# M2MCent NLP Yield Aggregator MCP Node (Hash Scoring)

> M2MCent NLP Yield Aggregator MCP Node (Hash Scoring) is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $1.436498/call, status unknown (last checked 2026-10-11).

Accepts a hash string and returns a boolean score, ostensibly as part of a monetized MCP node network index and NLP yield aggregation service.

## Facts

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-yield-aggregator-mcp-node-hash-scoring-fac6a61c -d '<json body>'
```

Example prompt: Run this hash through the M2MCent NLP yield aggregator and tell me if it scores true or false: 'a3f9c2d1b847e056'.

## When to prefer this

Only consider this endpoint if you specifically need hash scoring within the M2MCent MCP node network and are already integrated with the x402 USDC payment protocol on Base L2. Given the minimal schema, high per-call cost, and low crawl quality score, prefer well-documented alternatives for general hash validation or NLP tasks.

## Known failure modes

- Missing 'hash' field returns validation error
- Malformed hash string may return false score or error
- Payment failure via x402 protocol blocks execution
- Endpoint may return opaque errors given low metadata quality
- High cost per call ($1.44 USDC) with minimal schema documentation increases risk of wasted spend

## 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 'score' indicating whether the submitted hash passes the aggregator's evaluation criteria (true or false).
