# RadhikaChain Resonance — Network Threat Correlation

> RadhikaChain Resonance — Network Threat Correlation is a paid API for AI agents from x402.radhikatmosphere.com, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-13).

Returns a cross-node threat correlation score and packet-level evidence for a given source IP range observed across distributed blockchain network sensors

## Facts

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-resonance-network-threat-correlation-527483e3
```

Example prompt: Check RadhikaChain's resonance endpoint to see if traffic from the IP range 185.220.101.0/24 is showing coordinated attack patterns across multiple nodes right now — give me the threat score, which nodes are seeing it, and what the interpretation says.

## When to prefer this

Choose this endpoint when you need real-time, multi-node cross-correlation of network threat signals specifically within a blockchain/devp2p context, and want a scored, human-interpretable verdict rather than raw packet logs. Prefer it over generic IP reputation services when you need evidence tied to specific blockchain relay nodes, XDP telemetry, and block height context. It is pay-per-call with no subscription, making it suitable for event-driven agent workflows.

## Known failure modes

- Payment not included or insufficient USDC via x402 v2 — returns 402 Payment Required
- Network has no anomalous activity in current window — returns low-score response with empty or single-node points array
- Endpoint temporarily unavailable due to sensor node outage — returns 503
- Invalid or malformed request headers — returns 400 Bad Request
- Rate limiting if x402 payment is replayed — returns 402 or 429

## 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 float threat score (0–1), a list of corroborating network nodes each with region, weight, packet count, source IP range, first-seen timestamp, and XDP program ID, the current block height, a human-readable interpretation of the observed pattern, the observation window in seconds, and the number of corroborating nodes.
