curl -X POST https://apiforagents.dev/v1/facebook \
  -H "Authorization: Bearer $AFA_KEY" \
  -H "Content-Type: application/json" \
  -d '{"op":"comments","subjects":["https://www.facebook.com/nike/posts/<post-id>"],"sort":"top","limit":50,"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":"comments","subjects":["https://www.facebook.com/nike/posts/<post-id>"],"sort":"top","limit":50}'

Inputs

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

Input	Type	What it does
subjects *	text list	Post, reel or photo permalinks. 1-5 items
includeReplies	boolean	false: top-level comments only; true (default) also returns the replies nested under them.
sort	enum	top = Facebook's "most relevant"; threaded = all comments in thread order.
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.

Show all 16 rows

Field	Type
commentUrl	string
commentText	string
commenter	string
commenterId	string
commenterUrl	string
commenterPicture	string
likes	integer
replies	integer
replyDepth	integer
isReply	boolean
replyingTo	string
threadRootAuthor	string
commentDate	string
commentMediaType	string
commentMediaUrl	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.

commenter	commentText	likes	replies	commentDate	isReply
Ravi Kumar	Can't wait to try the pumpkin latte!	24	2	2026-10-14	false
Lena Müller	Are you open on Sunday?	6	1	2026-10-14	false
Brewlab Coffee	@Lena yes, 8 to 4!	11	0	2026-10-14	true

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 comment	1	$0.0022
5 comments	5	$0.011
A full page	100	$0.225

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 Comments 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.

Questions people ask.

What does the Facebook Comments API return?

One row per comment: commenter, comment text, likes, reply count, date, whether it is a reply, its depth and who it replies to, comment URL, commenter id and URL, and any attached media URL.

What do I pass in?

Up to five post, reel or photo permalinks in subjects. Set sort to top (most relevant), threaded or newest, includeReplies to false for top-level comments only, and a limit from 1 to 100.

How much does it cost?

$0.0022 per comment 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.
