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: a Merkle root hash string (cryptographic fingerprint of chain state), the current block height (integer), and the total leaf count in the Merkle tree (integer). Example: {root: 'e96b3eac15c5...', height: 45058, leaves: 2}.
Example use cases
Auditing chain state integrity
“Pull the current Merkle root and block height from RadhikaChain so I can verify our on-chain data hasn't been tampered with since our last audit checkpoint.”
ZK proof pipeline bootstrapping
“I need the latest chain telemetry snapshot from RadhikaChain — specifically the Merkle root and leaf count — to bootstrap our Halo2 proof generation pipeline.”
Real-time block height monitoring
“Check the current block height and Merkle root on RadhikaChain right now and tell me if it's advanced since height 45000.”
Technical details
Endpoint
POSThttps://x402.radhikatmosphere.com/poiWhen to prefer
Choose this endpoint when you need a cryptographically verifiable, pay-per-use chain state snapshot (Merkle root + block height) without requiring account registration or subscription — especially in ZK proof pipelines using Halo2, Nova, or Plonky3, or when auditing on-chain data integrity on Base. Prefer over subscription-based RPC providers when you need occasional, accountless, micropayment-gated chain telemetry.
Side effects
- 402 Payment Required — x402 payment header missing or insufficient USDC amount
- Invalid payment — wrong chain (must be Base eip155:8453) or wrong token (must be native USDC)
- 503/timeout — chain telemetry service temporarily unavailable
- Malformed response if chain state is mid-update
- Payment facilitator rejection if x402 scheme version mismatch (must be v2 exact)
