What the API Migration Checker — Free Online Tool does

The API Migration Checker reviews code that calls OpenAI-style APIs and flags anything that would block a move to another OpenAI-compatible provider: SDK calls, endpoint paths, authentication headers, and request or response fields. It is built for developers planning a provider switch with minimal downtime. Plugsky implements an OpenAI-compatible interface, so most migrations mean changing the base URL, API key, and model name. Use the checker to confirm what else needs attention.

How to use it

  1. Collect the files and services that call the AI API.
  2. Map each call: SDK used, endpoint, auth header, streaming and response parsing.
  3. Note unsupported endpoints and provider-specific parameters.
  4. Change the base URL, API key, and model names for the new provider.
  5. Run your test suite against both providers before cutting production over.

FAQ

What breaks when switching to an OpenAI-compatible API?

Usually little. Base URL, API key, and model names change. Problems cluster around proprietary endpoints, provider-specific parameters, fine-tuning jobs, and any code that parses raw responses. A migration checker helps surface these before you cut over.

Can I keep using the OpenAI SDK?

Yes. OpenAI-compatible providers such as Plugsky work with the official SDKs by pointing the base URL at the new endpoint and using a Plugsky key. Keep the SDK version pinned and rerun your test suite after the switch.

How do I test a migration safely?

Replay a fixed set of real prompts against both providers, compare outputs, latency and error handling, then canary a small share of production traffic. Keep the old credentials active so rollback is a configuration change.
