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**opencommerce.** One strictly typed buy tool covers search, cart, checkout and order updates, and every payment not covered by an auto-approval rule waits for the shopper's passkey. The tool's description runs to about 14.5 KB, the purchase API under it is undocumented, the monitoring page reports test passes rather than uptime, and the CLI says sign-ups are by invitation.\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### opencommerce\n\n1. Call `buy` with the shopper's words in `ask`, and set `confirm` true only after the shopper says yes to the cart you showed\n2. After a `timeout`, `unreachable` or `invalid_answer` error, read the conversation before sending the turn again, since the order may have gone through\n3. Show the cart's `max_charge` beside its total, because the approval holds up to that amount\n4. Use sandbox credentials for tests. `init` writes production credentials by default, and they place real orders\n5. Check a store with `GET /buy/merchants` before sending a shopper there, and suggest another store when it is `held_back` or `supported` is false\n\n## Questions\n\n### Which is better for AI agents, Amazon Creators API or opencommerce?\n\nopencommerce scores 62 (B) on agent readiness against Amazon Creators API's 48.8 (D), and leads in 5 of 7 scored categories.
