What people build with the Facebook Followers API

Audience research

See what kind of people and pages follow a brand in your market.

Find partners

The pages a brand follows are often the partners and creators it works with.

Map a network

Walk out from a few known pages to see who sits around them.

Quote it, then run it

1. free quote: the exact price, nothing charged

curl -X POST https://apiforagents.dev/v1/facebook \
  -H "Authorization: Bearer $AFA_KEY" \
  -H "Content-Type: application/json" \
  -d '{"op":"followers","subjects":["natgeo"],"direction":"following","limit":25,"estimateOnly":true}'

2. the same call, run

curl -X POST https://apiforagents.dev/v1/facebook \
  -H "Authorization: Bearer $AFA_KEY" \
  -H "Content-Type: application/json" \
  -d '{"op":"followers","subjects":["natgeo"],"direction":"following","limit":25}'

Inputs

Everything you can send in one followers call. Required inputs first.

Input	Type	What it does
subjects *	text list	Page URLs or vanity handles. 1-3 items
direction	enum
limit	integer	1-100

What comes back

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
profileId	string
followerName	string
profileUrl	string
avatarUrl	string
bio	string
relationship	string
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.

A sample answer

Made-up names and values in the real field names, so you can see the shape before you spend anything.

Pricing

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 profile	1	$0.0067
3 profiles	3	$0.02
A full page	100	$0.675

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.

Try it without writing code

Open the Facebook Followers API in the playgroundThe 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.

Why this one, and not a scraper you run yourself

No login, no Facebook account, no cookies, no proxies, no browser to babysit.
When the site changes its pages, your request stays the same: keeping the reads working is our job, not yours.
A fetch that fails costs nothing: it is named in the answer with a reason, and the quote says the most a call can cost before it runs.

Use it from your tools

Questions people ask.

What does the Facebook Followers API return?

One row per profile: name, bio, whether it is a follower or a following, profile id, profile URL and avatar URL.

What do I pass in?

Up to three page URLs or vanity handles in subjects, direction set to followers or following, and a limit from 1 to 100.

How much does it cost?

$0.0067 per profile 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.

Why people pick API for Agents

One key for 26 platforms: social, commerce, jobs, places, search and contacts, with one request shape and one response shape.
A free quote before any spend: add "estimateOnly": true to any call and see the most it can cost.
Pay per record in US dollars. No subscription, nothing expires, top-ups from $5.
$0.10 free to try, no card. An AI agent can sign itself up in one request; a person claims it later.
Measured, not estimated: every answer says when each row was measured, whether it was fresh or a recent capture, and how sure to be of each field.
Partial success is success: anything that could not be fetched is named with a reason, and the charge settles to what came back, never above the quote.
Typed fields that keep their names whichever source answered, and a details object last with everything else the source sent, under our own field names.
Try any endpoint in the playground and download the answer as CSV or JSON.
