Nullifier Hash Generator MCP
x402
Nullifier Hash Generator MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.4/call, status unknown (last checked 2026-10-12).
Generates a cryptographic nullifier hash from input data, enabling zero-knowledge or privacy-preserving protocols to prevent double-spending or double-voting.

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
A cryptographic nullifier hash string derived from the provided input data, suitable for use in zero-knowledge proof systems, privacy-preserving protocols, or double-spend prevention mechanisms.
Example use cases
ZK double-spend prevention
“I have a commitment value '0xdeadbeef9876' and I need to generate a nullifier hash from it to prevent double-spending in my zero-knowledge payment protocol — can you compute that?”
Anonymous voting nullifier
“Generate a nullifier hash from the string 'voter_secret_42_roundId_7' so I can ensure this vote can only be cast once in my privacy-preserving voting system.”
Semaphore identity signal
“I'm building a Semaphore-style ZK app and need a nullifier hash derived from this identity commitment: 'identity_trapdoor_xyz_externalNullifier_clubA'. Can you generate it?”
Technical details
Endpoint
POSThttps://api.m2mcent.com/nullifier-hash-generator-mcp/api/process?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, on-demand nullifier hash computation for ZK proof systems, anonymous voting, or double-spend prevention without running your own cryptographic infrastructure. Suitable for agents operating in blockchain or privacy-preserving contexts that need a simple REST interface to nullifier generation.
Side effects
- Empty or missing 'data' field returns an error or null hash
- Malformed input string may produce unexpected hash output
- Service unavailability or timeout returns a non-200 response
- Payment failure (x402) if USDC balance is insufficient — request blocked before processing
