Check if an email is registered on Trello

Digital Footprint checks Trello as part of every lookup. Send an email address, phone number, or username and get back whether an account exists there, along with 800+ other platforms, breach history, and public web mentions, in one request.

One request

POST /v1/lookup?wait=true

curl -X POST "https://api.digifootprint.dev/v1/lookup?wait=true" \
  -H "Authorization: Bearer dfp_your_key" \
  -H "Content-Type: application/json" \
  -d '{"query": "someone@example.com"}'

What a Trello result looks like

From results[]

{
  "platform": "trello",
  "registered": true,
  "method": "public_api",
  "checkedAt": "2026-08-26T11:40:55.902Z"
}

checkedAt is the real moment this was established, not the moment you asked, so you can always tell a fresh answer from a cached one. If Trello blocked us or timed out, it is omitted from the response entirely rather than returned as registered: false.

Why teams use this

For fraud and AML teams, a thin footprint is a signal: an address with no accounts anywhere is a different risk profile from one with a decade of history. Checking Trello on its own tells you little. Checking it alongside hundreds of others in one call is what makes the signal usable.
