# RadhikaChain Defense Ledger — Attack Telemetry Feed

> RadhikaChain Defense Ledger — Attack Telemetry Feed is a paid API for AI agents from x402.radhikachain.xyz, paid per call via x402, $1.0296/call, status unknown (last checked 2026-09-15).

Returns real-time network attack telemetry including attacker IPs, attack type, affected node, packet counts, and threat intensity (prana) for monitored blockchain infrastructure.

## 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-defense-ledger-attack-telemetry-feed-60cdc7ec
```

Example prompt: Pull the latest attack telemetry from RadhikaChain's defense ledger — I want to see which IPs are currently hitting our seed nodes, what kind of attacks they're running like rpc_probe or policy_drop, the packet counts, and their prana threat scores.

## When to prefer this

Choose this endpoint when you need real-time, per-request blockchain network attack telemetry without a subscription — specifically when you want attacker IP sets, attack classification (rpc_probe vs policy_drop), per-node threat intensity (prana), and packet-level data. Prefer it over generic threat feeds when your concern is blockchain seed node and RPC infrastructure specifically. The pay-per-call x402 model makes it suitable for sporadic polling or event-driven agents that don't need continuous streaming.

## Known failure modes

- Missing or invalid x402 payment header returns HTTP 402 with payment requirements
- Insufficient USDC balance causes payment rejection before data is returned
- Service temporarily unavailable if RadhikaChain infrastructure is under active DDoS
- Empty attacks array returned if no attack events have occurred in the current window
- Network timeout if the upstream telemetry pipeline is lagging

## 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

Returns a JSON object with an 'attacks' array where each entry contains: timestamp (ts), comma-separated attacker IPs, attack kind (e.g. rpc_probe, policy_drop), affected node identifier, prana intensity score (float), and total packet count. Multiple simultaneous attack events may be returned per call.
