Please help me write a data collection script with the EveryInfra Polymarket Events endpoint (polymarket/events).

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 polymarket and action to events, and put the parameters inside params.
- No required parameters.
- Optional parameters:
  - category: Event category for events, such as Crypto, Sports or Politics.
  - keyword: Words to find in market or event titles, at least 3 characters, such as bitcoin or election; leave it out to list everything by the chosen order.
  - sort: Order of the list. markets: volume (default), open_interest, price_desc, price_asc, expiration, created, volume_1d, volume_7d, trades_1d. (allowed: created / end_date / open_interest / start_date / trades_1d / volume_1d / volume_7d / volume_all_time)
  - status: open (still trading) or closed (finished); leave it out for both. (allowed: closed / open)
  - limit: The most rows to return in this call, an integer from 1 to 100. The default applies when you leave it out, and a call can return fewer rows. Larger values return 422 before any charge. (default: 20)
- Returns a list of records. Main fields of each record: id (Polymarket ID of the market or event, a…), slug (Short name of the market or event in Po…), url, title, description, tags (Tags), status (open (still trading) or closed (finishe…), market_count (Number of markets in the event (events)), volume_usd (Total traded value in US dollars), liquidity_usd (Current order-book liquidity in US doll…), open_interest_usd (Current open interest in US dollars (ev…), volume_24h_usd (Traded value in the last 24 hours, US d…); 20 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=polymarket.
- Example request body:
{
  "platform": "polymarket",
  "action": "events",
  "params": {}
}
- Price: $6.81 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.
