## 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 telemost-telegram-engagement-analytics-0c955d66
```

Example prompt: Show me the daily engagement rate, ERR, and ERR24 trends for the Telegram channel @durov over the past month — I want to benchmark how active their audience is.

## When to prefer this

Use this endpoint when you need quantitative engagement time-series metrics specifically for Telegram channels, including ER, ERR, and ERR24. Prefer this over general social analytics tools when working specifically within the Telegram ecosystem and needing granular control over aggregation periods.

## Known failure modes

- Channel not found or invalid channel identifier — 404 or empty result
- Channel has insufficient data for the requested aggregation period
- Invalid aggregation enum value — validation error
- Payment not completed (x402 protocol) — 402 Payment Required
- Rate limit exceeded — 429 Too Many Requests

## How this service works

Telegram engagement analytics: engagement rate (ER), engagement rate by reach (ERR) and 24-hour reach engagement (ERR24) over time. Benchmark audience activity and channel performance.

## Output

A time-series dataset containing ER (engagement rate), ERR (engagement rate by reach), and ERR24 (24-hour reach engagement) metrics for the specified Telegram channel, aggregated at the requested granularity (day, week, month, or year).
