Telegram Username Checker — Bulk Channel, Group & Bot Lookup

Turn @usernames and t.me links into a table of known channels, groups and bots.

Part of TGDen — Telegram Intelligence. No Telegram account, phone number or session is required.

Turn source research into buyer discovery

Found a source group or channel? buyerSearchUrl opens a Buyer Search preview for its known country, and buyerSearchInput carries the same country into the Apify export. Where country is unknown, the link opens Buyer Search so you can choose a market. A source lookup does not establish buying intent.

Use this input, run the Actor and open its dataset (JSON, CSV or the table view):

{
  "entities": [
    "@durov",
    "t.me/rent_in_dubai",
    "@combot"
  ]
}

Real output

A shortened row read on 23 October 2026 during owner-account acceptance testing. Results change as the corpus changes.

[
  {
    "input": "durov",
    "type": "channel",
    "status": "active",
    "reason": null,
    "username": "durov",
    "title": "Pavel Durov",
    "url": "https://t.me/durov",
    "audienceSize": 10857676,
    "audienceCheckedAt": "2026-09-07T09:12:37.378015Z"
  }
]

The dataset contains the delivered rows. The run's OUTPUT record adds counts, an explicit outcome (results, valid_zero_result, limited or incomplete), source timings and any stop reason. A source failure fails the run; it is never presented as a successful empty search.

Cost

$0.005 per run start + $0.002 per matched entity delivered. With the 256 MB memory limit there is one start event. Ten billable results cost about $0.025 in Actor fees. Zero matches incur only the start fee. Prices and any platform charges shown by Apify at launch are authoritative.

Set Maximum charge per run before starting (default $0.50). Delivery stops when the remaining budget cannot pay for another result; duplicate results are not billed twice in a run. Apify free-plan accounts receive at most 50 billable results per run. The amount of data in a snapshot may be larger than your budget permits.

Freshness and interpretation

Results come from an existing catalog, not a live Telegram check. Use each audience or signal measurement timestamp. Some observations can be weeks old; null means unmeasured. Coverage and matches vary by topic and language.

This is a catalog lookup. not_found means absent from this catalog; it does not mean the username is available to register. Private or excluded records are not enriched. Diagnostic rows are free; only matched entities are billable. Duplicate username spellings are normalized. Bots retain not_checked status.

Why use it

Enrich a mixed list in one run with explicit missing statuses, types, audience and links.

This Actor reads public catalog data. It does not join groups, send messages or contact anyone. Verify the source and suitability before outreach or business decisions.

API and scheduled runs

Use the same JSON input with the public Actor API. Keep your Apify token in an environment variable.

curl -X POST \
  -H "Authorization: Bearer $APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  --data @input.json \
  "https://api.apify.com/v2/acts/telegrambest~telegram-entity-enrichment/run-sync-get-dataset-items?memory=256&timeout=180&maxTotalChargeUsd=0.50"

For longer runs use Apify's asynchronous run endpoint and fetch the dataset after completion. Where available, onlyNew=true remembers delivered items for this Actor and your account so scheduled searches skip them. Keep it off when you want a full repeatable snapshot.
