## 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-cybersecurity-metadata-validator-mcp-b3673544 -d '<json body>'
```

Example prompt: Can you validate this cybersecurity metadata string for me and tell me if it's legitimate: '{"cve":"CVE-2024-1234","severity":"high","source":"nvd"}'?

## When to prefer this

Use this endpoint when you need a fast, automated boolean check on whether a cybersecurity metadata string is valid or legitimate, especially in pipelines ingesting external threat intel, CVE feeds, or security alert data. Prefer this over manual review when you need programmatic true/false gating of security metadata at scale.

## Known failure modes

- Missing or empty 'data' field returns a validation error
- Malformed JSON input may cause a 400 error
- Non-string values in the 'data' field may be rejected
- Service unavailability or payment failure via x402 protocol results in 402 or 503 errors
- Ambiguous or non-cybersecurity strings may produce unreliable boolean outputs

## 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' — true if the input cybersecurity metadata string is considered valid/legitimate, false otherwise.
