Polymarket Trades API

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

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 trades, and put the parameters inside params.
- Required parameters:
  - market: The market for trades: its slug (such as will-donald-trump-win-the-2024-us-presidential-election), its 0x condition ID or its polymarket.com link, taken from a markets row.
- Optional parameters:
  - 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: 50)
- Returns a list of records. Main fields of each record: tx_hash (On-chain transaction hash of the trade…), order_hash (Hash of the order behind the trade (tra…), side (BUY or SELL, from the maker's side (tra…), outcome (The outcome traded, such as Yes or a te…), price (Trade price, 0 to 1 (trades)), shares (Shares traded (trades)), amount_usd (Trade value in US dollars (trades)), fee_usd (Fee in US dollars (trades)), traded_at (Trade time, ISO 8601 UTC (trades)), market_slug (Slug of the traded market (trades)), condition_id (The market's on-chain condition ID (0x.…), token_id (ID of the outcome token traded (trades)); 15 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=polymarket.
- Example request body:
{
  "platform": "polymarket",
  "action": "trades",
  "params": {
    "market": "will-bitcoin-reach-110000-by-december-31-2026-658-339-969"
  }
}
- 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.
