Facebook API
Comment replies
The reply thread under one Facebook comment — chain feedback_id + expansion_token from facebook/post-comments. Facebook hides some reply threads; an empty list is the platform's real answer, not an error.

Query parameters
| Name | Required | Description | Example |
|---|---|---|---|
feedback_id | yes | feedback_id from a facebook/post-comments row. | — |
expansion_token | yes | expansion_token from the same facebook/post-comments row. | — |
cursor | no | Opaque cursor from the previous page. | — |
dry_run | no | Read a zero-credit estimate without fetching sources, running AI, or reserving credits. Cache status is a snapshot, not a guarantee at execution. | 1 |
judgments | no | Add bounded AI labels to eligible returned records (default on). off preserves the original data shape. Unclassified records remain present; labels depend on evidence, time, capacity and the existing request budget. No label surcharge. | on |
label | no | Set none to disable labels; default enables the endpoint’s label set. Equivalent to judgments=off. | none |
label_evidence | no | Include exact supporting sentences and zero-based sentence indexes when a label has validated evidence. No extra charge or change to decisions. | 1 |
exclude | no | Optionally remove confidently labelled engagement bait. Uncertain and unclassified records stay; removed IDs and an owner-bound recall reference are returned. | engagement_bait |
fit | no | Use goal to replace confidently irrelevant records with recall stubs. Keeps first, last, relevant and uncertain records; preserves order. Full evidence is stored for 24 hours when available. | goal |
goal | no | Required with fit=goal: describe the task in at most 600 characters. Supplied text is task context, never permission to act on posts. | Find concrete product complaints |
tokens | no | Optional soft response target for fit=goal, 256–32000. Safety and evidence retention take priority, so the returned result may exceed it. | 4000 |

Response fields and example
This example is illustrative, not a captured live response. Variable-cost operations may settle a charge different from the list price below. A successful response puts the platform payload in data and reports the exact credits used, remaining balance, request id and cache status beside it.
{
"success": true,
"platform": "facebook",
"endpoint": "/v1/facebook/comment-replies",
"data": {
"cursor": null,
"dropped": 0,
"has_more": false,

}The example is illustrative and shows a documented subset of data. The fields below are optional across supported sources; nullable fields can also be absent. Preserve unknown values and accept additional fields.
Schema basis: observed response shapes, not an exhaustive field specification. See schema coverage and validation limits.
Download the data JSON Schema. Validate response.data, not the whole envelope. A valid shape does not establish that every field or source record was returned.
| Field inside data | Type | Meaning |
|---|---|---|
cursor | string | null | Opaque next-page token; pass it back unchanged. Null does not prove complete history. |
dropped | number | null | Optional dropped supplied by this operation. Null means unknown. |
has_more | boolean | null | Source continuation indicator; null means unknown. |
items | array | null | Returned records. Source coverage and completeness vary. |
items[].author | object | null | Public author information supplied with this record. |
items[].author.id | string | null | Source identifier. Preserve the supplied type and exact value. |
items[].author.name | string | null | Optional name supplied by this operation. Null means unknown. |
items[].created_at | string | null | Source creation time, not the API retrieval time. |
items[].expansion_token | string | null | Optional expansion token supplied by this operation. Null means unknown. |
items[].feedback_id | string | null | Optional feedback id supplied by this operation. Null means unknown. |
items[].id | string | null | Source identifier. Preserve the supplied type and exact value. |
items[].reactions | number | null | Optional reactions supplied by this operation. Null means unknown. |
items[].reply_count | number | null | Optional reply count supplied by this operation. Null means unknown. |
items[].text | string | null | Source text when supplied. |
Optional fields reviewed from preserved successful responses. Additive fields and source variations remain allowed; validate the fields your workflow requires.
The example is invented and illustrates types only; zero and empty values are not claims about a real result.
Failures use the typed error envelope. A confirmed uncharged or refunded failure reports zero; a pending reconciliation can report an unknown charge. Read credits_used and error.details.billing_status, and keep request_id for recovery. Response contract · Error reference
