What to check before you rely on a relay
A solid AI API relay should be judged by compatibility, response consistency, and how cleanly it fits your existing SDKs. Start with the basics: does it accept standard OpenAI-style endpoints, preserve request and response structure, and handle common model names without extra glue code? If your team uses Node, Python, or cURL, the setup should feel familiar rather than custom.
Next, test operational details. Look at latency under a few repeated requests, error clarity when you send a malformed payload, and whether rate limits are communicated in a way your app can handle. A relay is most valuable when it reduces friction; if every request needs manual adjustments, the time saved disappears quickly.
Smoke-test steps
- Confirm the base URL uses the expected OpenAI-style path.
- Send one small chat request with a short prompt.
- Repeat the same request three times and compare response time and output shape.
- Test one failure case, such as an invalid model name, to see whether the error is readable.
- Verify your logs show the request ID or enough detail for troubleshooting.
Config example
For many apps, the only change is the endpoint variable. Keep the rest of your integration the same.
This pattern works well when you want an OpenAI-compatible relay without rewriting your client logic. The point is to swap transport, not rebuild your stack.
