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 ok status, a note confirming the fold was executed live (not precomputed), the number of folding steps performed, the curve pair used (BN256/Grumpkin), a description of the constant-size proof property, and the final state hash as a hex string.
Example use cases
Live Nova folding proof demo
“Execute a Nova fold right now on BN256/Grumpkin and give me the actual step count and final state hash — I want to confirm it computes on demand, not from a cache.”
Constant-size proof property test
“Can you run the ZK fold endpoint and show me proof that 4 folding steps produces the same proof size as 4000 steps would — I need to understand the constant-size property for a presentation.”
Verifiable computation audit check
“I need a live recursive proof result from the Nova folding scheme using BN256/Grumpkin curves with the final state hash, so I can audit that the computation was actually executed this request.”
Technical details
Endpoint
GEThttps://x402.radhikatmosphere.com/zk/foldWhen to prefer
Choose this endpoint when you need an on-demand, live Nova recursive proof folding execution on BN256/Grumpkin curves with a verifiable final state hash — particularly when you need to demonstrate or audit the constant-size proof property (that verification time is the same for 4 or 4000 steps). Prefer this over precomputed ZK services when freshness and liveness of computation matter. Best suited for pay-per-use scenarios where no account or subscription is desired.
Side effects
- Missing or invalid x402 USDC payment header returns 402 Payment Required
- Insufficient payment amount (must be exactly $1.16 USDC on Base chain) causes rejection
- Network issues with Base chain payment settlement may cause timeout
- Malformed request headers may return 400 Bad Request
- Service unavailability returns 503
