It cannot place or follow orders, so a person buys through the affiliate link. Access needs an accepted Associates account with 10 qualifying sales in 30 days, and the Agent Terms require agents to identify themselves.\n\n**Walmart Affiliate Marketing API.** Live, free catalogue search and product lookup for approved Walmart affiliates, signed with an RSA key and capped at 5,000 calls a day. It cannot place or follow orders, and the Checkout API needs separate approval. The documentation renders only in a browser, and the API terms date from 2020 and still name a previous affiliate network.\n\n## Before you call either\n\n### Amazon Creators API\n\n1. Send x-marketplace as a header and marketplace and partnerTag in the body on every call\n2. Cache the access token for its 3,600 seconds and share it across processes\n3. Request only the resources the task needs, and use offersV2 for prices, because the older price resource is gone\n4. Set the user agent to Agent/\u003cname\u003e as the Associates Agent Terms require\n5. Hand purchases to the person through the returned detailPageURL without editing its parameters\n\n### Walmart Affiliate Marketing API\n\n1. Generate a fresh WM_SEC.AUTH_SIGNATURE for each call, because a signature older than 180 seconds is rejected\n2. Keep below 5,000 calls a day per application\n3. Pass the Impact publisher ID so returned links earn commission\n4. Hand purchases to the person through the returned product link, since the affiliate API cannot check out\n\n## Questions\n\n### Which is better for AI agents, Amazon Creators API or Walmart Affiliate Marketing API?\n\nAmazon Creators API scores 48.7 (D) on agent readiness against Walmart Affiliate Marketing API's 38.6 (E), and leads in 4 of 7 scored categories.
