See who follows a brand in your market and what kind of accounts they are.
The accounts a well known brand follows are often the creators and partners it works with.
Walk out from one account's following list to find more people to vet.

-d '{"op":"followers","subjects":["natgeo"],"direction":"following","limit":50}'Everything you can send in one followers call. Required inputs first.
| Input | Type | What it does |
|---|---|---|
| subjects * | text list | Usernames or profile URLs. 1-10 items |
| direction | enum | |
| limit | integer | 1-100 |
The fields of every row, always present. Nothing is guessed: a value that could not be measured is null, and the answer's coverage says why.
| Field | Type |
|---|---|
| username | string |
| fullName | string |
| igUserId | string |
| isVerified | boolean |
| isPrivate | boolean |
| avatarUrl | string |
| profileUrl | string |
| followers | integer |
| profile | object |
| details | object |
details is always the last field: everything else the source sent for that row, under our own field names. Its keys depend on the source that answered, so read them defensively; it is {} when there is nothing more.
Made-up names and values in the real field names, so you can see the shape before you spend anything.
| username | fullName | followers | details |
|---|---|---|---|
| ravi.k | Ravi Kumar | 412 | {} |
| lena_m | Lena M. | 2100 | {} |
| sam.runs | Sam Taylor | 96 | {} |
Pay as you go, in US dollars, per record. No subscription, nothing expires, $5 first top-up, and every new agent starts with $0.10 free.
| Request | Records | At the list price |
|---|---|---|
| One account | 1 | $0.000675 |
| 10 accounts | 10 | $0.0068 |
| A full page | 100 | $0.068 |
These are per-record list prices. Some calls also carry a minimum, such as a page of search results, so a small request can cost more than the table shows. The quote ("estimateOnly": true) is free, gives the most your exact request can cost, and the charge then settles to what came back. Records that do not come back are refunded.
One row per account in the list: username, full name, follower count and whether the account is already known to us.
Up to ten usernames or profile URLs in subjects, direction set to followers or following, and a limit from 1 to 100.
$0.000675 per account at the list price. A small call can carry a minimum, so quote first with "estimateOnly": true, which is free and is the most the call can cost. You pay for what comes back.
No. It reads the lists of public accounts only.
The playground runs any endpoint by hand: pick a platform and what you want from it, fill a short form named in plain words (or press Use sample input), see the free quote on the Run button, run it, then read the answer as a table or JSON and download it as CSV or JSON. The same call is written out as cURL, Python and Node while you type.
