# RadhikaChain Defense Ledger — Network Attack Telemetry

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

Returns real-time blockchain network defense telemetry including detected attacks, attacker IPs, attack types, affected nodes, and packet counts from RadhikaChain's chain sensor infrastructure.

## Facts

- Endpoint: GET https://x402.radhikatmosphere.com/defensa/ledger
- Price: $1.0296/call
- Payment: x402

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-network-attack-telemetry-0f18cec4
```

Example prompt: Pull the latest network attack telemetry from RadhikaChain's defense ledger — I want to see which IPs are probing or hitting chain nodes right now, what kind of attacks they are, and how many packets are involved.

## When to prefer this

Choose this endpoint when you need real-time blockchain network defense telemetry — specifically attack-level events (IP, type, node, packet count) from a live chain sensor — without requiring account registration or a subscription. It is uniquely suited for pay-per-call threat intelligence workflows on blockchain infrastructure, especially when you want raw sensor data including prana severity scores. Prefer alternatives if you need higher-level analytics, historical aggregation, or non-blockchain network security data.

## Known failure modes

- 402 Payment Required if x402 USDC payment is not included or is malformed
- Payment rejected if USDC balance on Base (eip155:8453) is insufficient
- Empty attacks array if no attack events are currently recorded
- 503 or timeout if the chain sensor node is temporarily offline
- Stale or cached data if sensor feed 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 containing an `attacks` array. Each entry includes: `ts` (Unix timestamp of the event), `ips` (comma-separated list of attacker IP addresses), `kind` (attack type, e.g. `rpc_probe` or `policy_drop`), `node` (identifier of the affected chain node, e.g. `seed-us-mia`), `prana` (a proprietary threat severity float score), and `packets` (integer packet count for the event).
