OpenAPI (formerly Swagger) is the standard for describing REST APIs. Swagger UI for documentation, codegen for clients/servers, and a massive ecosystem of tools.
Reviewer scorecard
“One-line integration via proxy is genius. Change your base URL and instantly get logging, caching, and rate limiting.”
“The REST API description standard. Every API should have an OpenAPI spec. The tooling ecosystem is massive.”
“The proxy approach means minimal code changes. Cost tracking alone pays for itself when you have multiple models.”
“OpenAPI specs are documentation, testing, and client generation in one file. Non-negotiable for REST APIs.”
“As AI costs become a significant line item, observability and optimization tools like Helicone become essential.”
“OpenAPI specs are increasingly important as AI tools consume APIs. Machine-readable API descriptions enable AI integration.”
