# TeleSint ASN Threat Intelligence Lookup

> TeleSint ASN Threat Intelligence Lookup is a paid API for AI agents from telesint-api.onrender.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-15).

Looks up an Autonomous System Number (ASN) against Telegram-sourced cyber threat intelligence, returning threat actors, C2 associations, abuse categories, phishing kits, bulletproof hosting indicators, and blocking recommendations.

## Facts

- Endpoint: GET https://telesint-api.onrender.com/asn
- Price: $0.03/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/telesint-asn-threat-intelligence-lookup-58b0919f
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_BavCSntPtQNa4xq9gYyQo

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 telesint-asn-threat-intelligence-lookup-58b0919f
```

Example prompt: Pull TeleSint threat intelligence on ASN AS215540 — I want to know if it's linked to bulletproof hosting, any C2 frameworks like Cobalt Strike, which threat actors are using it, and whether I should block it at the firewall.

## When to prefer this

Use this endpoint when you need Telegram-sourced, community-driven threat intelligence on a specific ASN — especially for identifying bulletproof hosting providers, C2 infrastructure, and phishing-as-a-service networks that may not appear in traditional commercial threat feeds. Prefer this over generic WHOIS or IP reputation services when you want MITRE ATT&CK-tagged, AI-enriched intelligence with real-world attacker attribution and WAF rule generation.

## Known failure modes

- Missing or invalid ASN parameter returns a 400 or error response
- ASN not found in Telegram CTI data returns empty or low-confidence result
- Payment not completed via USDC/x402 returns 402 Payment Required
- Render.com cold start may cause elevated latency on first call
- ASN data may be stale if not recently mentioned in monitored Telegram channels

## How this service works

ASN threat intel from Telegram CTI channels. Pass ?asn=AS215540. Returns C2/phishing-kit associations, threat actor mentions, bulletproof hosting flag, blocking recommendation with WAF hint, and record IDs for pivoting into /c2 or /ioc.

## Output

Returns a structured JSON object containing the ASN and org name, confidence level, data sources, a list of associated threat actors (e.g. Storm-1167, Scattered Spider), C2 framework associations, abuse categories (bulletproof hosting, phishing, C2), phishing kit associations (Tycoon2FA, etc.), a bulletproof hosting boolean indicator, count of Telegram channel mentions, recent Telegram intel record IDs, a WAF rule hint for Cloudflare/AWS WAF, a blocking recommendation, and freshness timestamp — all enriched by DeepSeek with MITRE ATT&CK tagging.
