Expedia Search API

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

Endpoint contract:
- 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 expedia and action to search, and put the parameters inside params.
- Required parameters:
  - keyword: Specifies the hotel destination for search actions or the pick-up location or full Expedia carsearch URL for car_rental.
- Optional parameters:
  - currency: Sets the display currency for hotel search pricing, defaulting to USD without modifying API billing currencies. It does not change the currency of car_rental results.
  - sort: Hotel result order for search: distance, price_asc, price_desc, or top_rated. Without it, results follow Expedia's recommended order. (allowed: distance / price_asc / price_desc / top_rated)
  - limit: The most rows to return in this call, an integer from 1 to 200. The default applies when you leave it out, and a call can return fewer rows. Larger values return 422 before any charge. (default: 24)
- Returns a list of records. Main fields of each record: hotel_id, name, url, neighborhood, region, rating, rating_scale, rating_label, review_count, star_rating, price_per_night, price_total; 18 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=expedia.
- Example request body:
{
  "platform": "expedia",
  "action": "search",
  "params": {
    "keyword": "Paris"
  }
}
- Price: $1.39 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.
