Search X (Twitter) accounts by keyword, as in the People tab: it matches usernames, display names and bios. Each account has bio, avatar, follower, following and post counts, verification and creation date. About 20 per page; page on with next_page_token. Posts are not returned.

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.

AI prompt

Please help me write a data collection script with the EveryInfra X (Twitter) User search endpoint (twitter/search_users).

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 twitter and action to search_users, and put the parameters inside params.
- Required parameters:
- keyword: A topic, name or username to match accounts on, such as ai agents; it returns accounts, not posts.
- Optional parameters:
- page_token: Page token for user_media, user_replies, retweeters, search_communities, community_posts and search_users. Leave it out for the first page, then pass back the previous response's next_page_token exactly as received.
- Returns a list of records. Main fields of each record: next_page_token, id, username, url, name, text, avatar_url, follower_count, following_count, post_count, is_verified, created_at.
- Example request body:
{
"platform": "twitter",
"action": "search_users",
"params": {
"keyword": "coffee"
}
}
- 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.

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
`next_page_token`	Keeps the platform's own meaning
`id`	The record's unique ID on the platform. Unique only within one platform; IDs can repeat across platforms.
`username`	Username (@handle).
`url`	Link to the record on the platform.
`name`	Name of the object itself, for account, product and business capabilities.
`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).
`avatar_url`	Avatar image link. Some platforms return sized CDN links that can expire.
`follower_count`	Followers. null means not disclosed, not 0.
`following_count`	Accounts followed. null means not disclosed, not 0.
`post_count`	Total posts. null means not disclosed, not 0.
`is_verified`	Whether the platform verified the account. null means it cannot be determined.
`created_at`	Creation time, same format as posted_at.
`platform`	Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok).
