# TeleSint Vulnerability Intelligence Feed

> TeleSint Vulnerability Intelligence Feed is a paid API for AI agents from telesint-api.onrender.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).

Retrieves AI-enriched vulnerability and exploitation intelligence from Telegram CTI channels, including CVE details, PoC releases, CVSS severity, MITRE ATT&CK mappings, and in-the-wild exploitation signals

## Facts

- Endpoint: GET https://telesint-api.onrender.com/vulnerability
- Price: $0.03/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

- Tags: x402
- Canonical page: https://www.zero.xyz/c/telesint-vulnerability-intelligence-feed-a22495b5
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_VLTzzI_1RuLsmOi6ZpphH

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-vulnerability-intelligence-feed-a22495b5
```

Example prompt: Pull the latest critical-severity vulnerability intelligence from TeleSint — filter for anything tagged 'exploit-in-the-wild' or 'poc' with at least 80 confidence, give me up to 20 results from the past week.

## When to prefer this

Use this endpoint when you need near-real-time vulnerability intelligence sourced from active Telegram CTI communities, especially for CVEs with PoC releases, exploitation-in-the-wild signals, or zero-days not yet widely indexed. Prefer this over NVD or Shodan when you want AI-enriched context, MITRE ATT&CK annotations, and community-sourced threat signals. Best for SOC teams, red teamers, and threat intel analysts who need timely exploit awareness with confidence scoring.

## Known failure modes

- Payment not included or insufficient USDC on Base mainnet — 402 Payment Required response
- Invalid severity enum value (must be critical/high/medium/low/info) — likely 400 or empty result
- Invalid ISO 8601 timestamp in 'since' parameter — malformed request error
- Limit exceeds 100 — capped or error response
- No matching records for applied filters — empty items array with total:0
- Service temporarily unavailable on Render free tier (cold start delay) — timeout or 503

## How this service works

CVE and exploitation-in-the-wild signals from Telegram CTI channels. Filters: severity, min_confidence, since, tag(cve|exploit|poc|patch), ttp, type(cve), limit, offset. Returns CVE IDs, affected products, exploit status.

## Output

A paginated JSON array of vulnerability intelligence records, each including CVE identifiers, CVSS severity, summary of exploitation activity, PoC links, affected products, MITRE ATT&CK technique mappings (e.g. T1190), TLP classification, AI confidence score (0-100), associated tags, originating Telegram channel, and timestamp. Total count and pagination metadata are included.
