Find Walmart products for a search term. Each product has brand, current and was price, rating, stock status, seller and UPC barcode. lang switches the display between English and French only. Results stay on the US storefront and do not confirm local store inventory.

Send POST https://api.everyinfra.com/api/v1/social with platform set to walmart and action set to search. Price $1.39 per 1,000 requests ($0.001389 per call). Failed calls and empty results are not charged. Synchronous. For slow jobs add "mode": "async" to the body, take the job_id and poll.

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

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 walmart and action to search, and put the parameters inside params.
- Required parameters:
- keyword: Specifies the product search term for the search action. The search targets the US Walmart storefront and fetches a single page of results. It does not search store locations or product reviews.
- Optional parameters:
- lang: Sets the display language for the search and profile actions. Allowed values are en (English, default) and fr (French). This parameter changes only the interface language, not the storefront region or review filtering. (allowed: en / fr)
- limit: The most rows to return in this call, an integer of 1 or more. The default applies when you leave it out, and a call can return fewer rows.
- Returns a list of records. Main fields of each record: item_id, name, url, price, was_price, currency, rating, rating_scale, review_count, in_stock, seller_name, category; 17 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=walmart.
- Example request body:
{
"platform": "walmart",
"action": "search",
"params": {
"keyword": "air purifier"
}
}
- 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.

Response fields

Business data is in results. The table lists the fields a record can contain; values the platform does not show are never made up.

Field	Meaning
`item_id`	Keeps the platform's own meaning
`name`	Name of the object itself, for account, product and business capabilities.
`url`	Link to the record on the platform.
`price`	Price as a number without a currency symbol; see currency.
`was_price`	Keeps the platform's own meaning
`currency`	Currency code of the price (for example CNY, USD). If price is present but currency is null, do not assume a currency.
`rating`	Rating. The scale varies by platform: rating_scale on the same row gives the maximum (usually 5; Booking, Douban, iQIYI and NAVER use 10). Convert with rating_scale before comparing across platforms, or the comparison can come out backwards.
`rating_scale`	Maximum of rating in the same row: 5 for five-star scales, 10 for ten-point scales. Present only when the row has a rating.
`review_count`	Number of reviews, for product and business capabilities. null means not disclosed, not 0.
`in_stock`	Keeps the platform's own meaning
`seller_name`	Keeps the platform's own meaning
`category`	Category name in the platform's own taxonomy, not normalized across platforms.
`image_url`	Image link. Capabilities with several images may return an image_urls array.
`platform`	Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok).
`brand`	Keeps the platform's own meaning
`availability`	Keeps the platform's own meaning
`condition`	Keeps the platform's own meaning
`upc`	Keeps the platform's own meaning
