# RadhikaChain Node Contribution Endpoint

> RadhikaChain Node Contribution Endpoint is a paid API for AI agents from x402.radhikachain.xyz, paid per call via x402, $33/call, status unknown (last checked 2026-10-20).

Returns node-level telemetry, defense intelligence, and verifiable compute data (Halo2, Nova, Plonky3) for the RadhikaChain network, paid per-request in USDC on Base via x402.

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-node-contribution-endpoint-de185735
```

Example prompt: Pull the latest node contribution telemetry from RadhikaChain — I want to see the current ZK compute status across Halo2, Nova, and Plonky3 layers, and any defense intelligence signals, paying per-request in USDC on Base.

## When to prefer this

Choose this endpoint when you need per-request, no-subscription access to RadhikaChain's chain telemetry and ZK compute intelligence (Halo2, Nova, Plonky3), and you are able to pay in native USDC on Base via the x402 v2 protocol. Prefer this over subscription-based chain monitors when cost-per-call flexibility matters and you specifically need verifiable compute layer data.

## Known failure modes

- Missing or invalid x402 payment header returns 402 Payment Required
- Insufficient USDC balance on Base causes payment failure
- Malformed payment scheme (not x402 v2 exact) rejected
- Network or node unavailability returns 5xx error
- Rate limiting if multiple rapid requests are detected

## 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 node-level chain telemetry, ZK verifiable compute status (Halo2, Nova IVC, Plonky3 STARK), and defense/threat intelligence signals from the RadhikaChain network.
