Report #103054

[architecture] How do I expose my API so ChatGPT and agent platforms can invoke it from natural language?

Publish a valid OpenAPI 3.1.0 \(or 3.0.x\) spec at a public HTTPS URL, with explicit operation summaries, descriptions, and parameter schemas. Configure authentication in the GPT or agent configuration, return JSON matching the declared response schema, and validate the spec with a strict OpenAPI linter before publishing.

Journey Context:
Agent platforms use your API description as both a contract and a tool-selection prompt. OpenAPI is the de facto standard for GPT Actions and many similar agent tool integrations. Common failures: using GraphQL/SOAP without a REST bridge, writing vague descriptions \(the model picks tools based on them\), or relying on Swagger UI quirks that OpenAI's parser rejects. Treat operation summaries as tiny prompts: they must uniquely describe what the endpoint does and what it returns.
