Last updated October 2026Maintained by the SocialCrawl team

What can you do with the Post Comments API?
The Post Comments endpoint gives you structured Facebook data with computed fields in a single request. No scraping infrastructure to build or maintain.
Example Request
curl -H "x-api-key: YOUR_API_KEY" \
"https://www.socialcrawl.dev/v1/facebook/post/comments?url=https%3A%2F%2Fwww.facebook.com%2FMeta%2Fvideos%2Fa-slightly-life-changing-story%2F1459847961114516%2F&label=purchase_intent"import requests
response = requests.get(
"https://www.socialcrawl.dev/v1/facebook/post/comments",
params={
'url': 'https://www.facebook.com/Meta/videos/a-slightly-life-changing-story/1459847961114516/',
'label': 'purchase_intent',
},
headers={"x-api-key": "YOUR_API_KEY"},
)
data = response.json()const response = await fetch(
"https://www.socialcrawl.dev/v1/facebook/post/comments?url=https%3A%2F%2Fwww.facebook.com%2FMeta%2Fvideos%2Fa-slightly-life-changing-story%2F1459847961114516%2F&label=purchase_intent",
{
headers: { "x-api-key": "YOUR_API_KEY" },
},
);
const data = await response.json();Parameters worth sending
label=purchase_intentMarks each comment that shows buying intent, at no extra credits; sentiment, question and complaint are free too.
Parameters
| Parameter | Required | Description |
|---|---|---|
| url | No | Full URL of the Facebook post to fetch comments for |
| feedback_id | No | Using feedback_id (instead of url) will *really* speed up the request. You can get the feedback_id when you make a request to /v1/facebook/post. |
| cursor | No | Cursor to get more comments. Get 'cursor' from previous response. |
| label | No | Optional CSV of SocialCrawl labels to add to every comment: sentiment, spam, question, purchase_intent, complaint, toxic, low_quality, injection. Without this param every page already carries sentiment, question, purchase_intent and complaint, free; label= adds the labels you name to them (the defaults keep running). Each comment gains computed.labels with probabilities (0 to 1), so you choose the cut-off; a comment that could not be judged carries labels: null. sentiment, question, purchase_intent and complaint are free when asked for too; spam, toxic, low_quality and injection add 1 credit per started 25 newly judged comments (comments already labelled for anyone are free, and so is a cached page). injection flags text that addresses an AI system and tries to direct it (flagged, p); it never drops or rewrites a row. judgments=off (or label=none) turns the default labels off. data.labels reports what was judged and billed. |
| exclude | No | Optional CSV (spam, low_quality), only with the same preset in label. Drops comments whose probability is 0.8 or higher and lists their ids in data.labels.dropped_ids. A comment that could not be judged is never dropped. |
| judgments | No | Optional, on (the default) or off. By default every row gains free SocialCrawl judgments (computed.labels, and computed.relevance on search endpoints), reported in data.labels (mode default) and data.relevance (origin default), each with a status (complete, partial or skipped) and pending: the rows still being judged when the page was sent, which carry null now and are filled on your next call or cached read. Default judgments never add credits, never change an existing field, and never drop or reorder a row. off returns the page exactly as before, with none of those keys. label=none does the same. (on | off) |
| dry_run | No | Optional. When 1, return a cost preview for this labelled or relevance-filtered request without fetching the page or judging any row. data.estimate reports rows_expected, rows_cached, label_credits_min, label_credits_max and base_credits. 0 credits charged. (1) |
| label_evidence | No | Optional, only with label=. When 1, every labelled row also carries computed.labels_evidence.<preset> = { quote, sentence_index }: the sentence in the row that most clearly shows the label, copied verbatim. Absent or null when no single sentence shows it. (1) |
| fit | No | Optional. When goal, keep the rows and fields needed for the goal you pass in goal= (plus any that are uncertain, and the first and last), and replace the rest with a stub. data.held_back lists the held ids and a recall id that re-reads the full page from cache at no extra charge. Without this param the page is unchanged. (goal) |
| goal | No | Required by fit=goal. What you are trying to do, in your own words, up to 300 characters. |
| fit_tokens | No | Optional, only with fit=goal. Soft cap on how much of the page to keep, in tokens. Uncertain blocks and the first and last block are kept even if they exceed it. |
| since | No | Only rows published on or after this date: YYYY-MM-DD (midnight UTC) or an ISO 8601 timestamp. Rows older than it are left off each page. This list is not in date order, so the walk does not stop at the date: keep following `next_cursor`, and each page costs what a page costs even when every row on it is filtered out. A row with no date is kept. `published_after`, `start_date`, `from_date`, `publish_time` (`yesterday`, `this-week`, `this-month`, `last-3-months`, `last-6-months`) and `max_age_days` are accepted and applied as `since`. |
| until | No | Only rows published on or before this date: YYYY-MM-DD (that whole UTC day is included) or an ISO 8601 timestamp. Newer rows are left off each page and the walk does not stop, so older pages follow. A row with no date is kept. `published_before`, `end_date` and `to_date` are accepted and applied as `until`. |

}FAQ
Have a question? We got answers
Find answers to frequently asked questions about SocialCrawl's API, pricing, and capabilities.
Contact usHow do I get comments from a Facebook post?
Send a GET request to /v1/facebook/post/comments with either the post url or a feedback_id. SocialCrawl returns a comment array with author name, comment text, like count, reply count, and creation timestamp.
What is feedback_id and why should I use it?
feedback_id is Facebook's internal identifier for a post's comment thread. Calling /v1/facebook/post/comments with feedback_id is significantly faster than url. You get feedback_id from the /v1/facebook/post response.
How many comments can I paginate through?
Use the cursor parameter to walk through the full comment list. Each response includes a cursor for the next page. Keep calling until the cursor is empty. SocialCrawl handles the pagination tokens for you.
Are comment replies included?
The endpoint returns top-level comments with a reply count for each. Nested reply threads are not expanded inline. Use the reply count to decide which threads are worth a separate request for deeper analysis.
Can I use this endpoint for sentiment analysis?
Yes. Each comment comes with its raw text, author, and like count. Feed it directly into an LLM or classifier. Combine with /v1/facebook/post for reactions breakdown and full post context.
