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 'hash' field (boolean) indicating whether the zero-knowledge proof synthesis succeeded or the hash validated correctly.
Example use cases
ZK proof for identity attestation
“Run a zero-knowledge proof synthesis on this identity attestation payload and return whether the hash is valid: 'user:0xABCD1234,age:verified,ts:1720000000'.”
On-chain credential verification
“I need to synthesize a ZK proof for this on-chain credential blob — can you run it through the web3 ZK proof synthesizer and tell me if it comes back with a valid hash? Payload: 'cred:diploma,issuer:0xUNIV,holder:0xSTU'.”
Proof synthesis for smart contract input
“Before I submit this smart contract call, synthesize a ZK proof for the input payload 'contract:0xDEFI,action:swap,amount:500USDC' and confirm the hash result.”

Endpoint
POSThttps://api.m2mcent.com/web3-zk-proof-synthesizer-mcp-233/api/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to synthesize or validate zero-knowledge proofs via a remotely-hosted, monetized MCP node on Base L2 with per-call USDC micropayments and no gas overhead. Prefer it over self-hosted ZK compute when cost, context efficiency, and gasless settlement are priorities.
Side effects
- Missing or malformed 'payload' field returns a 400-level error
- Payment settlement failure via x402 may result in a 402 Payment Required response
- Invalid or unsupported payload format may return a failed hash (false)
- Network or node unavailability may result in timeout or 5xx error
- Malformed JSON body causes request rejection
