Browse the notes on one Xiaohongshu topic page, newest or most popular first. Get full text, all images, engagement counts and video details. Pass a 24-character topic_id or topic link. Pages hold up to 20 notes, and only a missing next_page_token marks the end.

Send POST https://api.everyinfra.com/api/v1/social with platform set to xiaohongshu and action set to hashtag. Price $5.56 per 1,000 requests ($0.005556 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 Xiaohongshu Hashtag endpoint (xiaohongshu/hashtag).

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 xiaohongshu and action to hashtag, and put the parameters inside params.
- Required parameters:
  - topic_id: The topic page ID for hashtag (24 characters), or a topic page link such as https://www.xiaohongshu.com/page/topics/<ID>, an app topic link or a Xiaohongshu short share link.
- Optional parameters:
  - page_token: Pagination cursor for the comments, sub_comments, search, user_posts, search_users and hashtag actions: pass back the next_page_token value from a row of the previous response to fetch the next page.
  - sort: Order of the topic's notes: newest puts the latest first (the same as omitting it) and popular puts the most popular first. Keep the same value while paging. (allowed: newest / popular)
- Returns a list of records. Main fields of each record: id, url (The record's link on Xiaohongshu), title, text (Note body or comment text), like_count (Like count), collect_count (Save count), comment_count, share_count, posted_at, image_url, author_name, author_id (The author's user ID); 20 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=xiaohongshu.
- Example request body:
{
  "platform": "xiaohongshu",
  "action": "hashtag",
  "params": {
    "topic_id": "5be3ef92a514290001a15147"
  }
}
- Price: $5.56 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.

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.
`url`	The record's link on Xiaohongshu. Links from search, note, profile and hashtag usually carry an access token, so they open in a signed-out browser (the token expires; call again for a fresh link). Note links from user_posts carry no token and need one to open in a browser: call note with the note ID to get a link that opens. Profile links from search_users carry no token either; call profile with the user_id for one that opens. Note links from pgy_content_square carry a token, except with `keyword`, where they carry none.
`title`	Title. null when the platform has no titles (for example text-only posts).
`text`	Note body or comment text. note and hashtag return the full body; search and user_posts may return a truncated excerpt (up to about 60 and 100 characters respectively). Call note with the note ID for the full text.
`like_count`	Like count. On note and comment results, the likes on that item; on profile, the total likes the account's notes have received. null means not public or not returned this time, not zero.
`collect_count`	Save count. On note results, how many times that note was saved; on profile, the total saves across the account's notes. null means not public or not returned this time, not zero.
`comment_count`	Comments. null means not disclosed, not 0.
`share_count`	Shares. null means not disclosed, not 0.
`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.
`image_url`	Image link. Capabilities with several images may return an image_urls array.
`author_name`	Author's display name.
`author_id`	The author's user ID. Pass it to profile or user_posts. Note results carry the 24-character ID from profile URLs; comment results (comments, comments_batch, sub_comments) usually carry a different 29-character form. The two forms of one person do not match, so convert them with the user_id that profile returns before de-duplicating across batches.
`avatar_url`	Avatar image link. Some platforms return sized CDN links that can expire.
`author_url`	The author's profile link. It carries no access token, so a signed-out browser cannot open it; the url that profile returns for the author_id opens directly.
`is_video`	Whether the note is a video note. The play URL is NOT part of the note detail response (since 2026-10-14): call the separate video action with the same note URL to fetch it; each call is billed per call.
`next_page_token`	Page token (search, comments, sub_comments, user_posts, search_users, hashtag): pass it back unchanged as page_token, with the other parameters the same, to fetch the next page.
`video_url`	Video playback link (MP4), signed and expiring; download promptly if you need to keep it. null for image notes or when not returned. It appears on search/user_posts rows and in the separate video action; the note detail does not carry it (since 2026-10-14) — call the video action with the same note URL when you need the play link.
`duration_sec`	Video length in seconds. null for image notes or when it was not returned this time.
`duration_seconds`	Duration in seconds. null for content that is not video or audio.
`platform`	Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok).
`images`	Image links. On note, hashtag, search and user_posts, every image of the note in order. On comment results (comments, comments_batch, sub_comments), the images attached to the comment, stickers included; an empty array means none. null means this item was not returned this time.
