How to Migrate an OpenRouter Integration to Another API Gateway
Migrating an OpenRouter integration is not a production-wide Base URL replacement. First capture the contract your application already depends on: protocol, SDK method, Model ID, response schema, streaming behavior, tool calls, errors, retries, and usage fields. Then test the candidate gateway with an isolated key and a small canary.
If the current OpenRouter integration works and its model catalog or routing behavior is important to the application, staying may be the correct decision. A second gateway can also be added as a tested backup without replacing the primary route. Full migration should happen only after the candidate passes the same workload-specific checks.
This tutorial uses BetterToken as a verifiable example of another gateway. It is not an OpenRouter clone, and an OpenAI-compatible label does not guarantee identical models, features, errors, or usage data.
