## 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-api-onrender-com-c2adaec8
```

Example prompt: Pull the latest pre-attack intent signals from Telegram for the healthcare sector in the US — specifically access_sale and ransomware intent types, limit to 20 results — I want to see if anyone is targeting hospital organizations before anything goes live.

## When to prefer this

Use this endpoint when you need early warning signals specifically sourced from Telegram channels about imminent cyberattacks, access sales, or ransomware targeting — before attacks are publicly reported. Prefer this over generic threat feeds when you want pre-attack intelligence with Telegram-sourced provenance and need to filter by sector, geography, or specific intent type like 0day or ransomware.

## Known failure modes

- No signals found matching the specified filters — returns empty results list
- Invalid intent_type enum value causes a 400 bad request error
- Rate limiting or payment failure results in 402 or 429 response
- Service temporarily unavailable on Render.com free tier cold start — returns 503
- Unrecognized country or sector value may return empty or unfiltered results

## How this service works

Pre-attack intent signals from Telegram: access sales, 0days, ransomware targeting. Filters: sector, country, organization, intent_type(access_sale|0day|ransomware|exploit), limit. Signals appear before attacks.

## Output

Returns a list of intent signal items sourced from Telegram CTI channels, each describing a pre-attack indicator such as an access sale, zero-day listing, ransomware targeting announcement, or exploit discussion, filtered by the requested sector, country, organization, and intent type.
