AI agents are now the primary way developers integrate with APIs. This guide introduces agent experience (AX) and outlines how to make your API agent-friendly, from a strong OpenAPI foundation to typed SDKs, structured docs, and purpose-built interfaces like MCP servers, agent skills, and AGENTS.md.

Learn how to generate a production-ready TypeScript SDK from an OpenAPI spec. Compare OpenAPI Generator with Stainless for type safety, retries, pagination, and streaming.

Learn how to maximize the growth potential of your API and minimize your costs at the same time.

A practical guide for API platform teams deciding between hand-written SDKs and generators like Stainless. It breaks down when generation wins (HTTP-heavy, multi-language, spec-driven clients), when custom code is better (logic-first libraries), and why a hybrid approach often delivers the best developer experience.

Learn how to convert APIs into MCP servers using OpenAPI and Stainless. A technical guide to structuring tools, schemas, and workflows when generating MCP servers.

SDKs aren't just wrappers. They shape developer experience, reduce support burdens, and future-proof your API for AI.
