Could you build this?
Partial The simulator UIs, CLI, and validation harness are buildable, but high-fidelity stateful clones of many third-party APIs and their accuracy claims require sustained, detailed work that vibe coding alone won't cover.
What it would actually take: A real version needs per-API stateful emulators that reproduce each service's edge cases, pagination, and error semantics, plus a continuous conformance suite that runs the same requests against live APIs. The hard part is the breadth and accuracy of API behavior modeling, which takes sustained engineering effort and access to real API documentation and sandboxes.
