The Email Footprint API checks whether a specific email address is registered across social media, shopping, and professional platforms. It returns a summary of stats and a per-platform breakdown including secondary metadata like usernames or account status where available. The lookup backend is load-balanced, so footprint scans run as asynchronous tasks:

Create a task with GET /api/footprint/create-task (this is where one lookup is charged). You receive a task_id.
Poll the task with GET /api/footprint/get-task?id=<task_id> until status is no longer a running state. Polling is free.

Email and username footprints share the same task endpoints — only the type parameter differs (email vs username).

Step 1 — Create Task

GET https://www.osintcat.net/api/footprint/create-task

string

required

The email address to scan (e.g., user@gmail.com)

string

default:"email"

The footprint type. Use email for this endpoint.

string

required

Your API key

Creating a task consumes exactly one lookup from your daily quota. Polling get-task does not.

Response Body

string

The identifier used to poll for results.

string

The initial task status (e.g., running, queued, pending).

object

Show properties

string

Your current plan.

string

Remaining lookups for the day (unlimited on the Max plan).

{
  "task_id": "f3c8a1e2-9b44-4d51-bd0a-1c2e3f4a5b6c",
  "status": "running",
  "_meta": {
    "plan": "researcher",
    "lookups_left": 4821
  }
}

Step 2 — Poll Task

GET https://www.osintcat.net/api/footprint/get-task

string

required

The task_id returned by create-task.

string

required

Your API key

Poll roughly once per second until status is no longer one of the running states (running, queued, pending, processing, started). A scan typically completes within a few seconds and is capped at ~3 minutes. Response Body

string

Current task status. While running it is one of running, queued, pending, processing, started. Any other value (e.g., done, finished) means the scan is complete.

object

Live progress / summary counters (populated as the scan runs).

Show properties

number

Number of platforms checked so far.

number

Total number of platforms in the scan.

number

Number of platforms where the email was found.

string

Elapsed scan time.

array

List of platform results (grows as the scan progresses).

Show item properties

string

Platform domain (e.g., github.com)

boolean

True if the email is registered on this platform

object

Metadata retrieved from the platform (usernames, IDs, status, etc.)
