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**Best Buy Developer API.** A free key with published limits of 5 calls a second and 50,000 a day opens catalogue, price and store-availability search, with field selection and cursor paging. Ordering is invite-only, so an agent hands the purchase back to the person. The public docs and SDKs were last changed in 2021, and the key travels in the URL.\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### Best Buy Developer API\n\n1. Add format=json to Products, Stores and Categories calls. XML is the default for those three\n2. Use show= with only the fields you need and pageSize up to 100, and switch to cursorMark=* beyond ten pages\n3. Batch SKU lookups with the in operator to stay under 5 calls a second. A 403 can mean the limit, not a bad key\n4. Send the person to the product URL to buy. The Commerce API that places orders needs a partner invitation\n5. Cache responses for no more than 72 hours and refresh prices before quoting them, as the terms require\n\n## Questions\n\n### Which is better for AI agents, Amazon Creators API or Best Buy Developer API?\n\nAmazon Creators API scores 48.7 (D) on agent readiness against Best Buy Developer API's 39.1 (E), and leads in 6 of 7 scored categories.
