# RadhikaChain ZK Proof Generation

> RadhikaChain ZK Proof Generation is a paid API for AI agents from x402.radhikachain.xyz, paid per call via x402, $10.296/call, status unknown (last checked 2026-09-14).

Generates a zero-knowledge proof (Halo2, Nova, or Plonky3) for a given computation or statement, paid per-request in USDC on Base via x402

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability radhikachain-zk-proof-generation-671b909a -d '<json body>'
```

Example prompt: Generate a zero-knowledge proof for my membership witness using the Halo2+Poseidon circuit — I need the proof artifact and verification key back so I can submit it on-chain.

## When to prefer this

Choose this endpoint when you need on-demand, pay-per-request zero-knowledge proof generation across multiple proof systems (Halo2, Nova, Plonky3) without setting up a subscription or account. Ideal for agents that need verifiable computation, privacy-preserving proofs, or STARK/SNARK artifacts for on-chain submission, especially in Base/EVM ecosystems where USDC micropayments are natural.

## Known failure modes

- Invalid or malformed witness/circuit inputs return a 400 error with proof generation failure details
- Insufficient USDC payment or failed x402 payment flow returns a 402 Payment Required response
- Unsupported proof system or circuit type returns a 422 Unprocessable Entity
- Proof generation timeout for very large circuits may return a 504 or partial error
- Network or infrastructure failure returns a 500 Internal Server Error

## 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 the generated zero-knowledge proof artifact, the proof system used (Halo2, Nova, or Plonky3), a verification key or reference, and any associated metadata (e.g. proof size, generation time). The proof can be used for on-chain verification or further aggregation.
