Amazon Creators API vs OpenAI Agentic Commerce Protocol for AI agents
Amazon Creators API is Amazon's REST product catalog API for Amazon Associates, which replaced the deprecated Product Advertising API 5.0. OpenAI Agentic Commerce Protocol is an open checkout protocol (with Stripe) and OpenAI's specs for merchants to send product feeds to ChatGPT and accept orders from it.
The short answer
- Amazon Creators API: Affiliate publishers who already earn Amazon Associates sales and want live Amazon catalog data with tracked links.
- OpenAI Agentic Commerce Protocol: Merchants who want their products indexed and sold inside ChatGPT; it gives other agents no product catalog to search.
Side by side
| Amazon Creators API | OpenAI Agentic Commerce Protocol | |
|---|---|---|
| Searches | Amazon's product catalog by keyword, filters and browse node (SearchItems), plus item lookup by ASIN, product variations and the category tree. | – |
| Returns | Product details for items, their variations and browse-node (category) information; GetItems takes up to 10 item IDs per call. | – |
| Before the first call | An approved Amazon Associates account for the target marketplace with at least 10 qualifying sales in the past 30 days, then registration for API access in Associates Central and generated credentials (OAuth 2.0 client credentials). | For merchants: approval to onboard product feeds into ChatGPT (application at chatgpt.com/merchants), then a product feed and checkout endpoints that ChatGPT calls. |
| Acting on a result | Affiliate links: results are tied to your Associates Partner Tag, and buying happens on Amazon; the Associates rules forbid you placing orders on an Amazon site. | Checkout through the protocol: the merchant implements checkout-session endpoints that an agent calls, and stays the seller; OpenAI is not the merchant of record. |
| Limits on keeping or showing results | Product data other than images may be cached for up to 24 hours; images may not be stored (image links up to 24 hours); ASINs may be kept indefinitely. Shown prices need a date/time stamp. | – |
| AI in its terms | Program content may not be used to develop or improve large language, multimodal or machine-learning models. Separate Agent Terms require any agent using the content to identify itself in every request and not conceal that it is an agent. | – |
| Coverage | Amazon marketplaces worldwide; credentials work across marketplaces, but API access must be approved in each region and needs a Partner Tag for that marketplace. | – |
| MCP server | No official server listed | – |
