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 with: the Merkle tree depth (k), a success flag (ok), the Poseidon-hashed Merkle root using audited Orchard/Zcash constants (hash), an asymmetry score (asimetria), and a privacy statement confirming that leaf and path data are never logged or returned — only the root is public.
Example use cases
On-chain state inclusion check
“I need to verify that a leaf is included in our blockchain state Merkle tree without revealing which leaf it is — can you get me the ZK Merkle root with depth 4 and confirm only the root is public?”
ZK proof audit for DeFi protocol
“We're auditing our DeFi protocol's Merkle proofs — can you compute the Poseidon-hashed Merkle root using the audited Orchard/Zcash constants and give me the asymmetry score and depth?”
Privacy-preserving membership proof
“I want to prove membership in a set without revealing which member I am — run the ZK Merkle proof on RadhikaChain and return only the public root, keeping the leaf and path hidden.”
Technical details
Endpoint
GEThttps://x402.radhikatmosphere.com/zk/merkleWhen to prefer
Choose this endpoint when you need a privacy-preserving Merkle root computation using audited Poseidon hash constants (Orchard/Zcash) without leaking leaf or path witnesses. It is ideal for zero-knowledge inclusion proofs where the caller must not expose which leaf is being proven. Prefer it over general Merkle libraries when you need on-demand verifiable computation billed per-call via x402 USDC on Base, with no account or subscription required.
Side effects
- Payment not included or insufficient USDC — returns 402 Payment Required
- Invalid or malformed request parameters — returns 400 Bad Request
- Service temporarily unavailable — returns 503
- ZK circuit computation timeout for large trees — returns 504
- Network congestion on Base chain causing payment verification delay
