# RadhikaChain — Node Contribution Resource (x402)

> RadhikaChain — Node Contribution Resource (x402) is a paid API for AI agents from x402.radhikatmosphere.com, paid per call via x402, $171.6/call, status unknown (last checked 2026-09-15).

Returns blockchain telemetry, defense intelligence, and verifiable compute data (Halo2, Nova, Plonky3) for a specific node, paid per-request in USDC via x402.

## Facts

- Endpoint: GET https://x402.radhikatmosphere.com/contribuir/nodo
- Price: $171.6/call
- Payment: 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-resource-x402-f52aa8b9
```

Example prompt: Pull the latest chain telemetry and verifiable compute data from RadhikaChain for the /contribuir/nodo endpoint — I want the node contribution metrics and any defense intelligence signals returned.

## When to prefer this

Choose this endpoint when you need per-request, no-subscription access to RadhikaChain-specific node telemetry, ZK proof data (Halo2, Nova, Plonky3), or chain defense intelligence on the Base network, and you are able to pay $33 USDC per call via x402. Prefer this over general blockchain explorers when you specifically need verifiable compute proofs or defense intelligence signals tied to node contributions.

## Known failure modes

- 402 Payment Required if x402 USDC payment on Base (eip155:8453) is missing or insufficient
- Invalid or malformed payment header results in rejection
- Node not found or unavailable returns empty or error JSON
- Network latency on Base chain may delay payment confirmation
- Stale or cached data if node telemetry feed is temporarily offline

## How this service works

## Output

A JSON response containing chain telemetry data, defense intelligence indicators, and verifiable compute proof metadata (Halo2, Nova, Plonky3) associated with the queried node's contributions on the RadhikaChain network.
