Reddit Search API

Please help me write a data collection script with the EveryInfra Reddit Search endpoint (reddit/search).

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 reddit and action to search, and put the parameters inside params.
- Required parameters:
  - keyword: Specifies the post search query for search. Does not search full comment text. Defaults to relevance sorting; the time window is fixed to the past month.
- Optional parameters:
  - sort: Orders Reddit post listings by newest, popular, relevance, rising, or top. The post_detail and comments actions do not accept sort. (allowed: controversial / newest / popular / relevance / rising / top)
  - limit: The most rows to return in this call, an integer from 1 to 25. The default applies when you leave it out, and a call can return fewer rows. Larger values are accepted and capped at the maximum. (default: 10)
- Returns a list of records. Main fields of each record: id, url, title, text, author_username, community, like_count, comment_count, posted_at, flair, domain, external_link; 14 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=reddit.
- Example request body:
{
  "platform": "reddit",
  "action": "search",
  "params": {
    "keyword": "mechanical keyboard"
  }
}
- Price: $0.79 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.
