# RadhikaChain ZK Prove — Verifiable Computation Endpoint

> RadhikaChain ZK Prove — Verifiable Computation Endpoint is a paid API for AI agents from x402.radhikatmosphere.com, paid per call via x402, $10.296/call, status unknown (last checked 2026-09-16).

Generates zero-knowledge proofs using Halo2, Nova, or Plonky3 proving systems, paid per-request in USDC via x402 on Base.

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-prove-verifiable-computation-endpoint-adaa6891 -d '<json body>'
```

Example prompt: I need to generate a zero-knowledge proof for my Halo2 circuit — here are my public inputs and witness data. Use RadhikaChain's ZK prover and pay the $1.98 USDC fee via x402 on Base.

## When to prefer this

Choose this endpoint when you need on-demand, pay-per-use ZK proof generation without managing your own prover infrastructure. It supports multiple modern proving systems (Halo2, Nova, Plonky3), making it suitable for diverse circuit types. Prefer it when you want to avoid subscription overhead and pay only $1.98 USDC per proof via x402 on Base. It is particularly suitable for agents needing verifiable computation in blockchain or privacy-preserving contexts.

## Known failure modes

- Invalid or malformed witness/circuit inputs return a proof generation error
- Unsupported proving system selection returns a 400-level error
- Payment failure or insufficient USDC balance via x402 returns a 402 Payment Required response
- Proof generation timeout for large circuits may result in a timeout or error response
- Missing required fields in the POST body return a validation 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 response containing the generated zero-knowledge proof artifact, along with associated metadata such as the proving system used, verification key or reference, and proof encoding. The proof can typically be submitted to an on-chain or off-chain verifier.
