# RadhikaChain Trace Scan — Chain Telemetry & Defense Intelligence

> RadhikaChain Trace Scan — Chain Telemetry & Defense Intelligence is a paid API for AI agents from x402.radhikatmosphere.com, paid per call via x402, $0.858/call, status unknown (last checked 2026-09-13).

Returns live blockchain telemetry including active IP peer counts, prana (network health score), new node discoveries, and cumulative daily prana metrics for chain defense intelligence.

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-trace-scan-chain-telemetry-defense-intelligence-788ea7d8
```

Example prompt: Pull the latest RadhikaChain trace scan — I want to see how many peers are active, the current prana score, how many new nodes joined, and what today's cumulative prana total looks like.

## When to prefer this

Choose this endpoint when you need live, pay-per-call blockchain network telemetry without requiring an account or subscription — particularly useful for monitoring chain health (prana), peer discovery rates, and defense intelligence on Base-adjacent infrastructure. Prefer this over centralized block explorers when you need raw peer-layer data (IP counts, new node emergence) rather than transaction or smart-contract data, and when x402 micropayment compatibility is already part of your agent's payment stack.

## Known failure modes

- 402 Payment Required if x402 USDC payment header is missing or invalid — must include exact 0.165 USDC on Base (eip155:8453)
- Payment facilitator rejection if USDC balance is insufficient or transaction malformed
- Stale or empty telemetry if the devp2p sensor has lost peer connectivity
- 503/timeout if the chain scanning backend is temporarily unavailable
- Malformed JSON response if upstream telemetry pipeline errors

## 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: `ips` (integer count of active peer IPs observed), `prana` (float network health/vitality score), `nuevos` (integer count of newly discovered nodes), and `prana_hoy` (float cumulative prana score for today). All values reflect live chain telemetry at time of request.
