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
A JSON object containing: `root` (hex-encoded Merkle root hash of the current ZK tree), `height` (current block height as an integer), and `leaves` (total number of leaves in the Merkle tree as an integer). This provides a compact, verifiable snapshot of chain inclusion state.
Example use cases
ZK Merkle inclusion audit
“Pull the current Merkle root and tree height from RadhikaChain so I can verify that a specific leaf is included in the Halo2 Poseidon membership tree right now.”
Chain state snapshot for compliance
“I need a cryptographic snapshot of the chain — fetch me the Merkle root, the current block height, and total leaf count from RadhikaChain so I can log it for our audit trail.”
Verifying a ZK proof off-chain
“Can you hit the RadhikaChain proof-of-inclusion endpoint and get me the latest Merkle root and height? I want to cross-check it against a proof we received from a counterparty.”
Technical details
Endpoint
POSThttps://x402.radhikachain.xyz/poiWhen to prefer
Choose this endpoint when you need a cryptographic Merkle proof-of-inclusion from a ZK-based chain (Halo2/Nova/Plonky3) without requiring an account or subscription — ideal for one-off, pay-per-use inclusion verification. Prefer this over on-chain RPC calls when you want a compact, pre-computed verifiable proof rather than raw block data, and when you need trustless attestation compatible with ZK circuit pipelines.
Side effects
- Payment failure: x402 payment not included or USDC balance insufficient — returns 402 Payment Required
- Invalid or malformed POST body — returns 400 Bad Request
- Chain data temporarily unavailable — returns 503 Service Unavailable
- Rate limiting if payment is valid but request volume is excessive
- Network timeout if ZK computation is delayed
