# RadhikaChain Cross-Machine Network Resonance Score

> RadhikaChain Cross-Machine Network Resonance Score is a paid API for AI agents from x402.radhikachain.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Returns a live cross-machine network resonance score derived from eBPF/XDP telemetry data collected across geographically distributed nodes, with per-data-point metadata including source node, timestamp, packet weight, and XDP program ID.

## Facts

- Endpoint: GET https://x402.radhikachain.xyz/resonance?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/radhikachain-cross-machine-network-resonance-score-a669b685
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_UpAX4xYY4YogUR54lv4jI

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-cross-machine-network-resonance-score-a669b685
```

Example prompt: Pull the current cross-machine resonance score from the RadhikaChain eBPF/XDP telemetry feed and show me each data point with its source node, packet weight, and XDP program ID.

## When to prefer this

Choose this endpoint when you need a real-time, multi-continental network coordination metric derived directly from in-kernel eBPF/XDP instrumentation rather than application-layer metrics. It is best suited for infrastructure monitoring agents that need per-node, per-program telemetry with packet-level granularity. If you need zero-knowledge attestation of the same score, prefer the ZK-attested sibling endpoint on the same host.

## Known failure modes

- Payment not included or insufficient USDC — returns 402 Payment Required
- Telemetry pipeline temporarily unavailable — may return 503 or empty data set
- No active XDP sensors reporting — score may be null or zero
- Network partition isolating reporting nodes — partial or stale data returned
- Rate limiting if called too frequently — returns 429 Too Many Requests

## 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 structured response containing the aggregate cross-machine resonance score along with an array of telemetry data points, each including the source node identifier, observation timestamp, packet weight, and XDP program ID, sourced from live eBPF/XDP instrumentation across geographically distributed infrastructure.
