## Parameters

| name | type | required | default | description |
|---|---|---|---|---|
| url | not declared | yes | not declared | Specifies the target URL corresponding to the requested action. Use public Page URLs for profile and user_posts, post URLs for post and comments, group page URLs or group identifiers for group_posts, and business page URLs for reviews (which appends /reviews). Arbitrary Facebook URLs cannot be interchanged across actions. |
| limit | integer (1–50) | no | 10 | The most rows to return in this call, an integer from 1 to 50. The default applies when you leave it out, and a call can return fewer rows. Larger values return 422 before any charge. |

## Response fields (items in `results`)

| field | meaning |
|---|---|
| id | The record's unique ID on the platform. Unique only within one platform; IDs can repeat across platforms. |
| text | Body text with HTML removed, returned in full and never cut short (on a few platforms the list results themselves carry only an excerpt; the platform's field notes say so). |
| author_name | Author's display name. |
| author_username | Author's username (@handle), usually usable in URLs. |
| depth | Comment level: 0 is a top-level comment, 1 is a reply to it, 2 is a reply to a reply. Rows at depth >= 1 reuse their parent comment group id — rebuild the tree with depth + reply_to_id. When the main source is unavailable, a backup returns top-level comments only, so every row has depth 0 and there are no reply rows. |
| reply_to_id | Id of the comment this row replies to (present only at depth >= 1; always null at depth 0). Reply rows reuse the parent group id as their row id, so treat this field as the parent link. |
| comment_url | Permanent link to this comment; on reply rows the link carries a reply_comment_id parameter pointing at the commented row. |
| author_id | Numeric user id of the comment author (stable identifier for cross-request deduplication). |
| author_url | Profile link of the comment author. |
| like_count | Likes. null means the platform or this capability does not disclose it; it is not 0. |
| reply_count | Replies, usually replies to a comment. null means not disclosed. |
| posted_at | Publish time in ISO 8601, UTC (for example 2026-08-07T12:34:56+00:00). Non-standard strings from the platform are passed through as is, so parse defensively. null means the platform does not disclose it. |
| platform | Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok). |

## Example

```bash
curl -X POST 'https://api.everyinfra.com/api/v1/social' \

  "params": {
    "url": "https://www.facebook.com/nasa"
  }
}'
```

```python
import os
import requests

response = requests.post(
    "https://api.everyinfra.com/api/v1/social",
    headers={"Authorization": f"Bearer {os.environ['EVERYINFRA_API_KEY']}"},
    json={
        "platform": "facebook",
        "action": "comments",
        "params": {
            "url": "https://www.facebook.com/nasa",

    timeout=120,
)
print(response.status_code)
print(response.json())
```

## Response example

Real response to the example request above, captured 2026-10-24T18:28:34Z. `results` and `count` are real with personal information (names, handles, avatars, profile links, contact details) removed; the list keeps the first 2 of 16. `id`, `billing` and `quota` differ on every call, so only their shape is shown.
