Facebook Marketplace listing details API

Please help me write a data collection script with the EveryInfra Facebook Marketplace listing details endpoint (facebook/marketplace_item).

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 facebook and action to marketplace_item, and put the parameters inside params.
- Required parameters:
  - url: One listing: a Marketplace item link (https://www.facebook.com/marketplace/item/<ID>/) or the numeric item ID (the id of a marketplace row).
- Returns one object. Main fields: id, url, title, text, price, price_text, original_price_text, currency, condition, attributes, location, latitude; 25 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=facebook.
- Example request body:
{
  "platform": "facebook",
  "action": "marketplace_item",
  "params": {
    "url": "https://www.facebook.com/marketplace/item/1656586118821988/"
  }
}
- Price: $0.96 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.
