# RadhikaChain POK — Verifiable Computation Proof Endpoint

> RadhikaChain POK — Verifiable Computation Proof Endpoint is a paid API for AI agents from x402.radhikatmosphere.com, paid per call via x402, $5.148/call, status unknown (last checked 2026-09-14).

Generates a cryptographic proof-of-knowledge (Halo2/Nova/Plonky3) for chain telemetry and defense intelligence, returning a verifiable ZK proof with status and claimed value, paid per-request in USDC on Base via x402.

## Facts

- Endpoint: POST https://x402.radhikatmosphere.com/pok
- Price: $5.148/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/radhikachain-pok-verifiable-computation-proof-endpoint-53ef0f50
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_cXo-BNViJjdu9ikk8Fe7b

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-pok-verifiable-computation-proof-endpoint-53ef0f50 -d '<json body>'
```

Example prompt: Run a verifiable proof-of-knowledge computation on RadhikaChain's POK endpoint for my chain telemetry query and return the ZK proof and claimed value — I'm fine paying $0.99 USDC per request on Base.

## When to prefer this

Choose this endpoint when you need pay-per-use, on-demand ZK proof generation (Halo2, Nova, Plonky3) for chain telemetry or defense intelligence without requiring an account or subscription. Prefer it over subscription-based ZK services when you want per-request USDC micro-payments on Base and need a canonical proof-of-knowledge attestation with a structured JSON response.

## Known failure modes

- Payment not included or insufficient USDC amount — returns x402 payment required error
- Invalid or malformed request payload — returns 400 bad request
- Proof generation failure due to unsupported computation parameters — returns error status
- Network congestion on Base causing payment settlement delay
- Rate limiting if too many sequential requests are made

## 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 'proof' field (ZK proof string), a 'status' field (e.g. 'ok'), and a 'claimed' integer representing the verified claimed value from the computation.
