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**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### 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### 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, opencommerce or Walmart Affiliate Marketing API?\n\nopencommerce scores 62 (B) on agent readiness against Walmart Affiliate Marketing API's 38.8 (E), and leads in every scored category.\n\n### Can an agent call opencommerce and Walmart Affiliate Marketing API without installing anything?\n\nYes. opencommerce has a hosted endpoint at https://api.agentcard.sh and Walmart Affiliate Marketing API at https://developer.api.walmart.com/api-proxy/service/affil/product/v2.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/opencommerce-vs-walmart-affiliate-api.json, and with the fewest tokens: https://www.anchorterminal.com/compare/opencommerce-vs-walmart-affiliate-api.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"opencommerce\", \"b\": \"walmart-affiliate-api\"}`.
