Affirm has a functional REST API with sandbox environment and OpenAPI documentation, supporting agent integration at the merchant level. However, agent discovery is limited by lack of MCP server, llms.txt, or prominent API docs on main site—developers must navigate to developer portal. The core weakness for autonomous agents is account creation: merchant onboarding requires KYC, legal agreements, and manual underwriting, making programmatic signup impossible. Pricing is transaction-based with no free tier, and while the API is reasonably reliable, the BNPL use case limits applicability for most agent workflows (agents cannot themselves finance purchases).
