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 verification result indicating whether the submitted Groth16 proof is cryptographically valid or invalid, typically including a boolean validity flag and possibly error details if the proof fails verification.
Example use cases
Blockchain zkApp proof gate
“I need to verify this Groth16 proof before allowing a user to access a private on-chain resource — can you check if this proof data is cryptographically valid?”
ZK credential verification
“A user submitted a zero-knowledge credential proof claiming they meet an age requirement without revealing their birthdate. Can you run this Groth16 proof through the verifier and confirm it checks out?”
Layer-2 rollup proof audit
“We received a batch rollup proof in Groth16 format from our L2 system. Can you verify this proof data and tell me whether it's legitimate before we finalize the state transition?”
Technical details
Endpoint
POSThttps://api.m2mcent.com/groth16-proof-verifier-mcp/api/processWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call Groth16 zero-knowledge proof verification service without setting up your own verifier infrastructure. Ideal for agentic workflows, AI pipelines, or serverless applications that occasionally need to gate access or confirm zkp validity without running a full blockchain node or custom cryptographic backend.
Side effects
- Malformed or incomplete proof data returns a validation error
- Proof that fails cryptographic verification returns an invalid result
- Unsupported proof format or wrong curve parameters causes rejection
- Missing or empty 'data' field returns a bad request error
- Proof data that is not properly encoded (e.g. wrong base encoding) causes parsing failure
