# RadhikaChain ZK Resonance — Verifiable Compute & Chain Defense Intelligence

> RadhikaChain ZK Resonance — Verifiable Compute & Chain Defense Intelligence is a paid API for AI agents from x402.radhikatmosphere.com, paid per call via x402, $0.5148/call, status unknown (last checked 2026-09-15).

Returns blockchain telemetry, defense intelligence signals, and verifiable zero-knowledge compute results (Halo2, Nova, Plonky3) for the RadhikaChain ecosystem, paid per-request via x402 USDC 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-resonance-verifiable-compute-chain-defense-intelligence-ddc73f3e
```

Example prompt: Can you pull the latest ZK resonance telemetry and chain defense signals from RadhikaChain — I need the Halo2/Nova/Plonky3 verifiable compute output for the current chain state, paying per-request in USDC?

## When to prefer this

Choose this endpoint when you need cryptographically verifiable zero-knowledge compute results (Halo2, Nova, or Plonky3) combined with live chain telemetry and defense intelligence, and you want pay-per-request access with no account or subscription required. Prefer it over generic blockchain RPC endpoints when ZK proof verification is a core requirement, and over subscription analytics services when you only need occasional, auditable, per-query access paid in native USDC on Base.

## Known failure modes

- 402 Payment Required — x402 payment header missing or USDC payment not confirmed on Base
- Invalid or expired payment — payment amount does not match $0.099 USDC exact scheme
- Network error — Base (eip155:8453) chain unavailable or congested
- Empty or null response — no current telemetry data available for the resonance/zk path
- Rate limit or facilitator rejection — payment facilitator declines the transaction
- Malformed JSON response — endpoint returns unexpected schema variant

## 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 blockchain telemetry metrics, chain defense intelligence signals, and outputs from verifiable zero-knowledge proving systems (Halo2, Nova, Plonky3). The exact schema may vary per sub-resource; the canonical catalog is available at GET /.well-known/x402.
