TripAdvisor Restaurants API

Please help me write a data collection script with the EveryInfra TripAdvisor Restaurants endpoint (tripadvisor/restaurants).

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 tripadvisor and action to restaurants, and put the parameters inside params.
- Required parameters:
  - keyword: Search query string for location lookup. The search action queries across hotels, restaurants, and attractions, while restaurants and attractions restrict search to their respective domain.
- Optional parameters:
  - content_type: Filters location photos by source. Allowed values are from_everyone (all photos), from_management (owner uploads), and from_travelers (visitor uploads). (allowed: from_everyone / from_management / from_travelers)
  - currency: Currency code for displayed location prices, defaulting to usd (common options include eur, gbp, and cny). The full schema enumeration is preserved, but supported historical codes may not yield active real-time prices. (allowed: aed / afn / all / amd / ars / aud / azn / bam)
  - lang: Two-letter language code (such as en or zh) for search, profile, restaurants, and attractions. The reviews action does not take this parameter. (allowed: aa / ab / ae / af / ak / am / an / ar)
  - limit: The most rows to return in this call, an integer from 1 to 30. The default applies when you leave it out, and a call can return fewer rows. Larger values return 422 before any charge. (default: 10)
- Returns a list of records. Main fields of each record: id, name, category, url, text, rating, rating_scale, review_count, price_level, ranking, address, city; 21 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=tripadvisor.
- Example request body:
{
  "platform": "tripadvisor",
  "action": "restaurants",
  "params": {
    "keyword": "Tokyo"
  }
}
- 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.
