# Genomics Metadata Validator MCP Node

> Genomics Metadata Validator MCP Node is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $1.371836/call, status unknown (last checked 2026-10-10).

Validates genomics metadata by accepting a prompt and returning a hash-based validation result via a monetized MCP node.

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 genomics-metadata-validator-mcp-node-17e9e1d0 -d '<json body>'
```

Example prompt: Can you validate this genomics metadata entry — specifically check whether the sample annotation fields and sequencing run metadata are correctly structured: 'SampleID: GSM123456, Organism: Homo sapiens, LibraryStrategy: RNA-Seq, Platform: ILLUMINA'?

## When to prefer this

Choose this endpoint when you need a lightweight, fast genomics metadata validation check via a monetized MCP node and are already operating within the x402 payment protocol on Base L2. Best suited for agents that need a binary pass/fail signal on genomics metadata strings without requiring a full bioinformatics pipeline integration. Prefer alternatives if you need detailed validation error messages or structured ontology feedback.

## Known failure modes

- Missing or empty prompt field returns a 400 validation error
- Malformed JSON in request body causes parse failure
- Payment not fulfilled via x402 protocol results in 402 Payment Required
- Ambiguous or unrecognized genomics metadata format may return hash: false without detailed error explanation
- Network timeout on MCP node may return 503 or connection error
- Response schema only returns a boolean hash with no detailed error messages, limiting diagnostic value

## 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' boolean field indicating whether the genomics metadata passed validation. A true value signals valid metadata; false indicates a validation failure or data integrity issue.
