Followers You Know API

Return the followers of the account named by user_id that the account behind your registered session also follows: the mutual-connection overlap from your perspective. Returns full user objects, cursor-paginated. Requires a registered session and a numeric user_id. Cost: $0.0008 per call.

GET user/followers_you_know returns the followers of a target account, identified by user_id, that the authenticated caller's own account also follows. It surfaces the mutual-connection overlap between the caller and the target, returning full user objects with cursor-based pagination via next_cursor and has_more.

Query Parameters

user_id*string

Numeric ID of the target account to compute shared followers against.

count?integer

Items per page. Defaults to 20; documented cap 100. NOTE: X returns this list in fixed chunks, so a small count may still return up to a full page (~100). Treat count as an upper-bound hint, not an exact limit; paginate with the cursor for more.

cursor?string

Pagination cursor from a previous response's next_cursor.

When to use

Use this endpoint when you need the intersection of a target account's followers with the accounts your own registered session follows, for example to show "people you both follow" on a profile. Reach for the plain Followers or Following endpoints instead when you need a target account's full follower or following list with no filtering against your own session.

Notes

  • Needs a session for the account you are reading: either register one once (POST /customer/session), or pass per-call inline credentials as x-auth-token and x-ct0 request headers, which let a single API key act as many accounts. Returns 409 session_required if neither is supplied, 401 session_dead when the session has expired.
  • Like the other follower-graph endpoints, next_cursor can stay non-null on the final page; stop when the users array is empty.

Pagination

This endpoint is cursor-paginated and returns roughly 20 records per call. Pass the next_cursor from each response back as the cursor parameter to read the next page. Stop when the records array comes back empty: follower-graph endpoints return a non-null cursor even on the final page, so the empty array is the only reliable stop signal. See Pagination for the full loop.

FAQ

How is this different from the regular Followers or Following endpoints in the Follower Graph category?

Followers or Following returns every follower or followed account of a single user with no filtering. This endpoint intersects two sets: the followers of user_id and the accounts your registered session follows. Use it only when you need the overlap, not the full follower list.

How do I know if there are more results, and what does each page cost?

Check has_more in the response; if true, pass the value from next_cursor as the cursor parameter on your next request. Each call costs $0.0008 regardless of how many users are returned, and count (default 20) controls page size, so fewer, larger pages reduce total cost for a full walk.
