Read the full description
An HTTP API for zero-knowledge proofs: prove that balance, stake, account age or tx count meets a threshold — the verifier learns only that, never the value. Five Groth16 circuits, zero public signals in the proof. Settles on Base mainnet in real USDC, 1 USDC per call over x402, no account. Limitation, stated on the landing page: the ceremony is single-party, so proofs are forgeable until three independent parties take part.

No Designing, compiling, and safely operating custom zero-knowledge Groth16 cryptographic circuits and smart contract payment verification requires specialized cryptographic engineering.
What it would actually take: Building this requires writing zero-knowledge arithmetic circuits using Circom or Halo2 to verify balance, transaction, or age thresholds without leaking private inputs, followed by trusted setup ceremonies for Groth16. It also requires an on-chain verification contract on Base (EVM), integrating an x402 payment wall in USDC, and maintaining a high-performance backend prover service (e.g., using snarkjs or rapidsnark) built by experienced cryptographers.
