  "textContent": "MetaForgeXAI:\n\n> For ML/AI inference APIs specifically, the gap between what standard API docs tools handle and what you actually need is real.\n>\n> A few things that have worked in practice:\n>\n> **For spec-first with ML workflows:**\n>  Scalar (scalar.com) has become my go-to over Swagger UI —cleaner interface, better DX, and it handles OpenAPI 3.1 well. If you’re building inference endpoints with structured input/output schemas, it renders those clearly.\n>\n> **For staying in sync automatically:**\n>  If you’re on FastAPI or LlamaIndex server, the auto-generated OpenAPI spec stays current by default.\n>  The problem is usually the _quality_ of the generated docs, not the sync. Adding response_model and docstrings to your routes goes a long way.\n>\n> **For internal ML team docs:**\n>  Mintlify has decent AI-specific components and stays reasonably priced for small teams. Worth evaluating\n>  alongside Apidog if you want the combined docs + testing workflow.\n>\n> **The real pain point nobody mentions:**\n>  ML API docs break down when you have dynamic schemas — models that return different response shapes depending on parameters. Standard OpenAPI tooling handles this poorly. If that’s your situation, supplementing with a Jupyter notebook or runnable code examples in the docs matters more than the tool choice.\n>\n> What does your inference API stack look like?\n>  That usually determines which approach fits best.\n\nShort reply you can use:\n\n> True, ML inference APIs are a different beast because of dynamic schemas. I’ve seen teams simplify this by keeping a single source of truth for spec + tests using tools like Apidog, then extending with examples/notebooks for the non-static parts.",
