# Walmart on Onekey

> 5 endpoints for Walmart (0 stable, 5 beta), 2 to 3 credits each. Category: E-commerce & marketplaces. One key, one JSON shape.

Base URL: https://api.onekey.dev
Auth: header `x-api-key: <key>`. Call shape: `GET /v1/{platform}/{endpoint}?{params}`.
Every response is `{success, data, metadata, error}`; check `success` first. Cost is in `metadata.credits_charged`. Free when served from cache (0.2 credit for a cached response over 100 KB). Failed and not-found calls are refunded.
Status: stable = verified against the live source; beta = not yet verified, fields may be missing.
Access: 5 of 5 endpoints are marked "needs a pack" or "may need a pack": free-grant credits reach only the open fetch path; a verified email and a purchased pack unlock the rest.
