x402
M2MCent ZK-SNARK Payload Verifier is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-19).
Verifies zero-knowledge SNARK proofs submitted as payload data, returning a transaction hash and success status on Base L2

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 JSON object containing a boolean 'success' field indicating whether the ZK-SNARK proof was accepted, and a 'txHash' string with the Base L2 transaction hash of the verification settlement.
Example use cases
On-chain proof verification for dApp
“I have a ZK-SNARK proof my dApp generated that I need verified on Base L2 — can you submit this encoded proof payload and tell me if it passed and what the transaction hash is?”
Automated credential attestation pipeline
“We're running an automated pipeline that needs to verify zero-knowledge credential proofs — can you process this zk-snark data string and confirm success with a tx hash so we can proceed?”
Audit trail for private computation
“I need to create an on-chain audit record for a private computation — please submit this ZK-SNARK payload for verification and give me the resulting transaction hash.”
Technical details
Endpoint
POSThttps://api.m2mcent.com/zk-snark-payload-verifier-mcp/api/process?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify a ZK-SNARK proof payload on Base L2 via a monetized MCP node and require an on-chain transaction hash as proof of verification. Prefer it over generic validators when you need gasless USDC settlement via the x402 protocol and a standardized MCP interface.
Side effects
- Invalid or malformed ZK-SNARK payload returns success: false
- Malformed data string causes processing error
- Payment failure (insufficient USDC) blocks execution
- Network or Base L2 congestion delays response
- Missing or empty 'data' field causes schema validation error
