Read comments on a YouTube video, up to 100 per call. Each comment has text, author, likes, reply count, date and a reply flag. Sort by newest or popular, and set a start date with since. Use reply_to_id to link replies. The full thread is not promised.

Send POST https://api.everyinfra.com/api/v1/social with platform set to youtube and action set to comments. Price $0.56 per 1,000 requests ($0.000556 per call). Failed calls and empty results are not charged. Synchronous. For slow jobs add "mode": "async" to the body, take the job_id and poll.

Please help me write a data collection script with the EveryInfra YouTube Comments endpoint (youtube/comments).

How the endpoint works:
- Request: POST https://api.everyinfra.com/api/v1/social with the header Authorization: Bearer <API key>. Read the key from the EVERYINFRA_API_KEY environment variable and never hard-code it.
- In the request body, set platform to youtube and action to comments, and put the parameters inside params.
- Required parameters:
  - url: The target URL required by YouTube actions. Use full channel URLs for profile and user_posts, or specific watch?v= and share links for video, comments, and transcript.
- Optional parameters:
  - since: The lower date bound for filtering channel videos, Shorts, or comments. It applies to those lists only.
  - sort: The sort order applied across YouTube actions. For search, accepted values are relevance, newest, most_viewed, and top_rated. For channel videos and Shorts, accepted values are newest, oldest, and popular. (allowed: newest / popular)
  - limit: The most rows to return in this call, an integer from 1 to 100. The default applies when you leave it out, and a call can return fewer rows. Larger values return 422 before any charge. (default: 20)
- Returns a list of records. Main fields of each record: id, text, author_name, like_count, reply_count, posted_at, is_reply, reply_to_id.
- Example request body:
{
  "platform": "youtube",
  "action": "comments",
  "params": {
    "url": "https://www.youtube.com/watch?v=dQw4w9WgXcQ"
  }
}
- Price: $0.56 per 1,000 requests; failed and empty results are not charged.
- For dozens or hundreds of targets, add "mode": "async" to the body: you get a job_id at once and poll GET https://api.everyinfra.com/api/v1/jobs/{job_id} for the result.
- On 422, fix the request using the suggested parameter names and allowed values in the error; on 429 or 503, wait for Retry-After and try again.

Before writing code, ask me which targets I need, how many, which fields, and what output format I want; then confirm the plan and the rough cost with me.

Request parameters

Name	In	Type	Required	Default	Description
`Authorization`	header	`string`	Yes	-	Bearer followed by your API key. Create it in the console; never put it in a URL or a code repository.
`platform`	body	`string`	Yes	`youtube`	Platform identifier, fixed value.
`action`	body	`string`	Yes	`comments`	Capability identifier, fixed value.
`url`	body.params	`string`	Yes	-	The target URL required by YouTube actions. Use full channel URLs for profile and user_posts, or specific watch?v= and share links for video, comments, and transcript. Channel metadata is derived from published content, and comments does not return channel community board posts.
`since`	body.params	`date`	No	-	The lower date bound for filtering channel videos, Shorts, or comments. It applies to those lists only.
`sort`	body.params	`string (enum)`	No	-	The sort order applied across YouTube actions. For search, accepted values are relevance, newest, most_viewed, and top_rated. For channel videos and Shorts, accepted values are newest, oldest, and popular. For comments, accepted values are newest and popular. Specifying this parameter on a single-video query does not filter that video's content.Allowed values`newestpopular`
`limit`	body.params	`integer (1–100)`	No	`20`	The most rows to return in this call, an integer from 1 to 100. The default applies when you leave it out, and a call can return fewer rows. Larger values return 422 before any charge.

Response fields

Business data is in results. The table lists the fields a record can contain; values the platform does not show are never made up.

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.
`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.
`is_reply`	Keeps the platform's own meaning
`reply_to_id`	Keeps the platform's own meaning
`platform`	Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok).
