# RadhikaChain CrowdSec Threat Intelligence Feed

> RadhikaChain CrowdSec Threat Intelligence Feed is a paid API for AI agents from x402.radhikachain.xyz, paid per call via x402, $3.0888/call, status unknown (last checked 2026-09-15).

Returns real-time per-IP threat intelligence from CrowdSec sensors, including ports probed, TCP flags, TTL, OS fingerprint, and attack classification, sourced from eBPF/XDP kernel telemetry.

## Facts

- Endpoint: GET https://x402.radhikachain.xyz/amenazas/crowdsec
- Price: $3.0888/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/radhikachain-crowdsec-threat-intelligence-feed-de8360e7
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_--T4DNPavGpMJjlF74ExK

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-crowdsec-threat-intelligence-feed-de8360e7
```

Example prompt: Pull the latest CrowdSec threat intelligence from RadhikaChain right now — I need the full list of active attacker IPs with their probed ports, TCP flags, TTL, and attack classification so I can push firewall block rules.

## When to prefer this

Choose this endpoint when you need granular, per-IP firewall-actionable threat intelligence with TCP-level detail (flags, TTL, port lists, OS fingerprint) rather than aggregated block counts. It is specifically sourced from eBPF/XDP kernel sensors (not iptables counters), making it higher fidelity for IDS/firewall rule generation. Prefer this over generic threat feeds when you need behavioral classification (port sweep vs persistent probe) and microsecond-precision timestamps per attacker IP, and when you are comfortable with pay-per-request USDC micropayments on Base via x402.

## Known failure modes

- Payment not included or invalid x402 USDC payment header — request rejected with 402
- Insufficient USDC balance on Base (eip155:8453) — payment failure
- Sensor data temporarily unavailable — may return empty threat list
- Rate limiting if payment is not accepted by the facilitator
- Network timeout reaching the eBPF/XDP telemetry backend

## 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 list of threat entries, each with: attacker IP address, TTL, list of probed ports, total probe count, TCP flag codes, probable OS, first-seen and last-seen timestamps (microseconds), and attack classification (e.g. port sweep, persistent probe). Also includes aggregate counts of distinct IPs and total events, plus a field explaining the data advantage over aggregated counters.
