Fetch Facebook comment replies on demand for $0.06 per request via MPP payment.
What it does
This endpoint retrieves replies to a specific Facebook comment. It is part of StableSocial, a pay-per-request social media data API covering TikTok, Instagram, Facebook, and Reddit (36 endpoints total). Every call costs a flat $0.06 in USDC, settled via x402 or MPP (Tempo). No API keys or subscriptions are required — payment itself serves as authentication.
The workflow is asynchronous: you POST to `/api/facebook/comment-replies` with a `post_id` and `comment_id` (plus an optional `cursor` for pagination and `max_page_size`). On success you receive a 202 response containing a JWT token. You then poll `GET /api/jobs?token=...` (free, but requires SIWX wallet auth proving you are the paying wallet) until the job status is "finished" and data is returned. Jobs typically complete in 5–60 seconds; tokens expire after 30 minutes. If the trigger POST itself fails (bad params, entity not found), you are not charged.
This endpoint depends on prior data collection: you should first trigger `/api/facebook/profile` for the target page/user, then `/api/facebook/posts` to collect posts, then `/api/facebook/post-comments` to collect comments, before fetching comment replies. Pagination is supported via `page_info.has_next_page` and a `cursor` field; each page requires a new paid POST.

Fit
Best for
- —AI agents that need on-demand Facebook comment reply data without managing API keys
- —Social media analytics pipelines requiring granular comment-level data
- —Researchers collecting Facebook conversation threads programmatically

Quick start
# Step 1: Trigger the job (requires MPP or x402 payment header)
curl -X POST https://stablesocial.dev/api/facebook/comment-replies \
-H 'Content-Type: application/json' \
-d '{"post_id": "123456789", "comment_id": "987654321"}'
# → 202 {"token": "eyJ..."}
# Step 2: Poll for results (free, SIWX wallet auth required)
curl https://stablesocial.dev/api/jobs?token=eyJ...Example
Request

}Response
{
"token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
}Endpoint
Quality
Full OpenAPI schema with clear request parameters, detailed guidance docs, and confirmed pricing ($0.06/request). The probe did not capture a 402 challenge because the endpoint only accepts POST (HEAD/GET returned 405), but the OpenAPI spec and landing page confirm it is live and operational. No example response data schema is documented for the actual reply payload.
Warnings
- —Probe returned 405 on HEAD/GET because this endpoint only accepts POST; the endpoint is not confirmed live via direct 402 challenge but is documented in the OpenAPI spec.
- —Response data schema for comment replies is not documented — the OpenAPI spec only shows a generic '200: Successful response' without a payload schema.
- —This endpoint has a dependency chain: you must first collect profile → posts → post-comments before fetching comment-replies.
- —No /docs, /pricing, or /README pages found (all return 404); documentation is embedded in the OpenAPI x-guidance field only.
