# Pedersen Commitment MCP

> Pedersen Commitment MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.4/call, status unknown (last checked 2026-10-16).

Generates or verifies Pedersen commitments for privacy-preserving cryptographic proofs over submitted data

## Facts

- Price: $0.4/call
- Payment: x402

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 pedersen-commitment-mcp-b333d922 -d '<json body>'
```

Example prompt: Create a Pedersen commitment for the string '42500' so I can commit to this bid value cryptographically without revealing it yet.

## When to prefer this

Choose this endpoint when you need a standard Pedersen commitment scheme for privacy-preserving use cases such as blind auctions, anonymous voting, or zero-knowledge proof construction, and you want a managed API rather than running your own cryptographic library. Prefer this over general hashing when you need the binding and hiding properties of a proper commitment scheme.

## Known failure modes

- Empty or malformed 'data' string returns a validation error
- Data exceeding field length limits may be rejected
- Network timeout on the POST request
- Payment failure (402) if USDC balance is insufficient
- Server error (500) if cryptographic backend is unavailable

## 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 Pedersen commitment output — typically a commitment value (point on an elliptic curve or encoded hash) and potentially a blinding factor, allowing the caller to later open or verify the commitment without revealing the original data prematurely.
