Facebook Comments API

Returns the top-level comments on a public Facebook post, photo, video or reel, most relevant or newest first, a page at a time. Each comment has its text, time, permalink, exact reaction count with the reactions by type, reply count, attached photo and whether the post's author wrote it, and the commenter's ID, name, profile link, picture and verified badge. It takes every link the Facebook Post API does.

Long arrays and strings are shortened for display; real responses are complete.

x-api-keystringheaderrequired

Your API key. Authentication

urlstringrequiredmax 2,048 chars

Facebook post, photo, video or reel URL, as the Facebook Post API takes it: /<page>/posts/<id>, permalink.php and story.php links, /photo/?fbid= and /<page>/photos/… links, reel, watch, video.php and /<page>/videos/… links, fb.watch and /share/p|v|r/ share links (m., mbasic. and web. hosts too), or a numeric post, photo or video ID. A comment's link (?comment_id=) reads its post's comments.

Examplehttps://www.facebook.com/cnn/posts/pfbid0zVcLXuYcv5N8D5oZn9NMU3R116cECPXJiKY6QyxiZGTA7eRDZb3zv3NkVwgC1GVdl

sortstring

Order of the results. relevance (default): Facebook's All comments view, the most relevant first, including the comments its default view filters out. newest: every comment, newest first.

One ofrelevancenewest

sincestringdate-time

Only items at or after this time: RFC 3339 (2026-10-01T12:00:00Z) or a date (2026-10-01, midnight UTC). On newest-first lists, paging stops when it is reached, so later pages are not fetched or charged.

Example2026-10-01

untilstringdate-time

Only items before this time (exclusive): RFC 3339 or a date (midnight UTC).

Example2026-10-08

limitintegermin 1max 10

Items per page, 1 to the endpoint's page size (its default and maximum; larger values are reduced to it). Omit it: every page costs the same, so a smaller limit means more pages to pay for.

Example10

cursorstring

page.next_cursor from the previous response. Send the same other parameters; omit to start from the first page.

url takes Facebook post and video links; another kind of link, or another platform's, fails free with invalid_input. Unknown parameters are rejected with a suggestion, never ignored (Requests). limit and cursor page through the list: see Pagination.

Parameters every endpoint accepts
max_ageintegermin 0

Accept a cached response up to this many seconds old. Cache hits cost 0 credits. Omit to always fetch fresh. The Cache-Control: max-age=N request header is equivalent; max_age wins when both are sent.

fieldsstring

Return only these fields of each item: comma-separated paths in the schema's notation (id,text,metrics.view_count,segments[].text; a parent path keeps the whole object). Unknown paths are rejected. Applied after the cache, so it changes neither the price nor cache hits; page and meta are always returned whole.

Response

application/json

200

{data, page, meta}. data is an array of up to 10 comment objects, Facebook's All comments view: every top-level comment, the most relevant first; page says how to get the next page; meta describes the request (meta). Fields only Facebook has are under platform_specific.facebook.

avatar_urlstring urinullable

Profile picture URL. Platform CDN URLs can expire within hours.

is_verifiedbooleannullable

Platform verification badge; null where the platform has no badge.

published_atstring date-timenullable

edited_atstring date-timenullable

When the comment was last edited, RFC 3339 UTC; null when never edited or when the platform marks edits without a time (see is_edited).

is_editedbooleannullable

is_pinnedbooleannullable

Pinned by the post's author.

is_liked_by_authorbooleannullable

approximate_fieldsstring[]

JSON paths of values rounded by the platform or parsed from display text. A list path (external_links) means the list may be incomplete. [] when all exact.

unknown_fieldsstring[]

JSON paths of lists whose [] means unknown rather than none (a source that cannot see them); null already means unknown for every other field. [] when every list is known.

not_found and private_or_unavailable are item-level: the request was fine, the item can't be returned.

400

400 Bad Request: 2 error codes. Free: errors cost nothing.

A parameter is missing or malformed, or the link is not one this endpoint takes.

Fix the parameter named in param as the message says. For a link of the wrong kind, call an endpoint listed in details.endpoints, when there is one.

The cursor is malformed or expired, belongs to another endpoint, or came with other parameters than the request that returned it.

Repeat the original request without cursor to start the list again.

401

401 Unauthorized: 1 error code. Free: errors cost nothing.

unauthorizedNo retry

The x-api-key header is missing, or its key is unknown or revoked. On the dashboard's routes: the session cookie is missing or expired.

Send a valid API key in the x-api-key header. No key yet? A person gets one at details.signup_url; an AI agent follows details.agent_auth_url.

402

402 Payment Required: 2 error codes. Free: errors cost nothing.

The account does not have enough credits for this request.

Have a person buy credits at details.purchase_url (or make them a checkout link with details.checkout), then repeat the request. Do not retry automatically.

The API key reached its spend limit for this period. The account may still have credits.

Wait until details.resets_at, or raise the key's spend limit (PATCH /v1/api_keys/{id}). Do not retry automatically.

403

403 Forbidden: 2 error codes. Free: errors cost nothing.

forbiddenNo retry

The API key is valid but may not make this request, and details.reason says why: the account is suspended, the key lacks the route's scope, waits for its owner to confirm it by email, has expired, or was used from an IP outside its allowlist, or a rotated key's previous secret was used for a call that needs the admin scope. A running job stops with it too when its account is suspended or the key that created it is revoked or expires. It is about the key, never the item: a private item is private_or_unavailable, also 403, so branch on the code.

Act on details.reason. suspended: contact support. scope: use a key with details.required_scope. previous_secret: use the new secret. key_pending: have the owner open the emailed link. key_expired or key_revoked: create a new key. ip_not_allowed: call from an allowed IP.

The item exists but is not public: it is private, age- or region-restricted, or needs a login to view. It shares 403 with forbidden (which is about the key), so branch on the code.

Only public items can be fetched. Do not retry.

404

404 Not Found: 1 error code. Free: errors cost nothing.

not_foundNo retry

The item does not exist or was deleted. On GET /v1/requests/{id}/response: the response was not kept (details.reason says why).

Check the link or ID. Do not retry.

429

429 Too Many Requests: 1 error code. Free: errors cost nothing.

rate_limitedYes, later

The account passed its runaway-protection ceiling: a high per-account limit that stops a broken client loop (plans have no rate limit). Requests without an API key (signup, the MCP server's tool listing and find_endpoint) are limited per IP address instead. It also stops an account whose failed requests in the last hour cost far more than its successful ones paid for: failures are free within a limit (the message says so), and successes raise it.

Wait the seconds in the retry-after header, then retry. If your steady traffic needs more, ask support to raise the ceiling; without an API key, send one.

500

500 Internal Error: 1 error code. Free: errors cost nothing.

internalYes, later

An unexpected error on SocialTap's side.

Retry with backoff. If it keeps happening, contact support with the request_id.

502

502 Bad Gateway: 1 error code. Free: errors cost nothing.

upstream_errorYes, later

The platform failed, or answered with something we could not read.

Retry with backoff. Failed requests are free.

503

503 Unavailable: 2 error codes. Free: errors cost nothing.

The platform refused every attempt, our own retries included.

Retry later with backoff. Failed requests are free.

overloadedYes, later

SocialTap was at capacity, or paused by its operators, and did not start the request. Nothing was fetched or charged.

Retry after the seconds in the retry-after header. Failed requests are free.

Items come in pages, Facebook's All comments view: every top-level comment, the most relevant first. To get the next page, send the same request plus cursor set to page.next_cursor from the previous response. Keep every other parameter the same (limit, max_age and fields may change); anything else that differs is rejected. When page.has_more is false the walk is over, and page.end_reason says why: only end means you have every item (the others say the platform or a page cap stopped the walk early).

The page object

has_moreboolean

True when another page exists; then next_cursor is set. An empty page with has_more true is not the end.

next_cursorstringnullable

Pass as cursor, with the same other parameters, to get the next page; null at the end.

next_cursor_expires_atstring date-timenullable

When next_cursor stops working, RFC 3339 UTC; null at the end. Don't store cursors.

end_reasonstringnullable

Why there are no more pages; null while has_more is true. end: the list ended, or reached since/until. platform_limit: the platform stops serving further pages although the list goes on. max_pages: SocialTap's cap on pages in one walk. New values may be added. A short or empty page is not the end: only has_more false is.

  • The price is per page: each successful page costs the same, whatever limit is and however many items it has. Empty pages are charged too (an empty page with has_more: true is not the end).
  • A limit below 10 doesn't save credits: the next request serves the rest of the same platform page, which is fetched again and charged as a page each time, and items can shift between those requests if the platform changes the list. Omitting limit is the cheapest way to walk the list.
  • Errors are free, including a rejected cursor.
  • Pages served from the cache are free.
  • An expired or altered cursor, or one sent with different parameters, fails with invalid_cursor (HTTP 400): Repeat the original request without cursor to start the list again.

Pagination guide

From 1 credit per page. Charged per successful page, whatever its number of items. Errors are free. The price depends on the source that produced the result, reported as meta.source; sources are tried cheapest first: Platform API → Public page.

Balance, sources and what you were charged

Your balance must be at least 1 credit to start a request; with less, it is refused with insufficient_credits (HTTP 402) and costs nothing. Only that minimum is set aside when the request starts.
