# Model Weights Hash Auditor MCP

> Model Weights Hash Auditor MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Audits and verifies cryptographic hashes of AI model weights to ensure integrity and authenticity

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 model-weights-hash-auditor-mcp-3425137d -d '<json body>'
```

Example prompt: Can you audit the cryptographic hash of these model weights and tell me whether they match the expected value and haven't been tampered with? Here's the model data: [paste model weights hash or identifier].

## When to prefer this

Choose this endpoint when you need to cryptographically verify that AI model weights have not been altered, corrupted, or tampered with — especially before deploying third-party or open-source models in production environments or regulated contexts where provenance auditability is required.

## Known failure modes

- Invalid or malformed input data returns an error response
- Model weights data too large or malformed to process
- Hash mismatch detected — integrity check fails with tamper warning
- Service unavailable or timeout for very large payloads
- Payment not processed (x402 protocol failure) resulting in 402 response

## 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 hash audit result indicating whether the provided model weights data passes integrity validation, including the computed hash, verification status, and any anomaly flags detected during the audit.
