# TeleSint Threat Velocity Monitor

> TeleSint Threat Velocity Monitor is a paid API for AI agents from telesint-api.onrender.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-20).

Returns acceleration metrics for Telegram-sourced threat activity — window counts, EWMA, and trend direction — scoped by sector, country, organization, or actor.

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-threat-velocity-monitor-4f939da8
```

Example prompt: Check if Telegram threat activity is accelerating against the healthcare sector over the last 30 days — I want to see whether the trend is accelerating, flat, or decelerating with EWMA metrics.

## When to prefer this

Choose this endpoint when you need to detect whether threat activity tempo is changing — not just whether threats exist, but whether they are ramping up, stable, or cooling off. Ideal for scheduled monitoring jobs, SOC escalation triggers, and proactive alerting workflows where rate-of-change in Telegram threat signals is more actionable than a static snapshot.

## Known failure modes

- Invalid or unsupported window value (outside 7–90 days) returns an error
- No data found for an obscure or misspelled scope parameter returns empty or null results
- Payment failure or expired x402 token results in 402 Payment Required
- Rate limiting may occur if called too frequently in rapid succession
- Render cold-start latency may cause occasional slow or timed-out responses

## How this service works

Call on a schedule to detect tempo changes. Acceleration of Telegram threat activity per preparation stage and category for a sector/country/org (or global): window counts, EWMA, trend accelerating|new|flat|decelerating.

## Output

Returns per-category and per-preparation-stage window counts, exponentially weighted moving averages (EWMA), and a trend classification (accelerating, new, flat, or decelerating) for Telegram threat activity scoped to the requested sector, country, organization, actor, or vendor over the chosen time window.
