Scorecard detail
Stripe is the reference vendor for API-first design, full stop. The OpenAPI specification at github.com/stripe/openapi covers 587 operations and is the source of truth for the official SDKs in Ruby, Python, Node, PHP, Java, .NET, Go, and iOS/Android. The marketing site, the documentation, and the developer hub all lead with the API. The dashboard is one client; there are many others. Combined weekly npm download volume across stripe, @stripe/stripe-js, @stripe/react-stripe-js, and @stripe/agent-toolkit exceeds 27 million.

Every Stripe workflow is programmatic. Account creation (Connect), customer management, billing, subscriptions, payment intents, setup intents, disputes, payouts, reporting, terminal hardware, climate contributions: all 587 OpenAPI operations span the complete platform surface, and the docs site documents every workflow. The official stripe CLI provides shell access including local webhook tunnelling for development. Test mode parity with production is exact.
