x402
RadhikaChain ZK Proof of Knowledge (PoK) Endpoint is a paid API for AI agents from x402.radhikachain.xyz, paid per call via x402, $5.148/call, status unknown (last checked 2026-09-15).
Generates a zero-knowledge proof of knowledge (Halo2/Nova/Plonky3) verifying a claimed value on-chain, returning a proof blob, status, and claimed count, paid per-call in USDC via x402.

How this service works
Telemetria de cadena, inteligencia de defensa y computo verificable (Halo2, Nova, Plonky3). Pago por peticion en USDC nativo en Base (eip155:8453) mediante x402 v2 scheme exact; sin cuenta ni suscripcion. Catalogo canonico: GET /.well-known/x402.
Output
Returns a JSON object containing a ZK proof blob (base64 or hex-encoded cryptographic proof artifact), a status field indicating success or failure ('ok'), and a claimed integer count representing the number of claims proven. The proof can be submitted on-chain or to a verifier for trustless validation.
Example use cases
ZK membership proof for private DeFi
“I need to prove I'm a member of an allowlist for a DeFi protocol without revealing my identity — can you generate a Halo2 zero-knowledge proof of membership with a claimed count of 4 using RadhikaChain's PoK endpoint?”
On-chain attestation for audit trail
“Generate a verifiable ZK proof of knowledge for my claimed transaction count of 4 that I can submit on-chain as a cryptographic attestation — use RadhikaChain's proof-of-knowledge compute endpoint.”
Verifiable computation for cross-chain bridge
“I need a Plonky3 STARK proof confirming a claimed value of 4 for a cross-chain bridge verification step — can you call RadhikaChain's PoK endpoint and give me the proof blob and status?”
Technical details
Endpoint
POSThttps://x402.radhikachain.xyz/pokWhen to prefer
Choose this endpoint when you need a pay-per-use, zero-knowledge proof of knowledge generated by a multi-scheme ZK backend (Halo2, Nova, Plonky3) without requiring account registration or subscriptions. It is ideal for agents needing on-demand cryptographic attestations, membership proofs, or verifiable computation results payable in USDC on Base via x402. Prefer it over hosted ZK SaaS platforms when you want per-call billing with no commitments and native Base USDC settlement.
Side effects
- Invalid or malformed proof request payload — returns error status
- Payment not included or insufficient USDC balance — x402 payment required before computation
- ZK circuit constraint violation — proof generation fails if inputs don't satisfy the circuit
- Rate limiting or capacity constraints — endpoint may reject requests under high load
- Network timeout during proof generation — verifiable compute may take longer than expected for complex circuits
