JEVROUTER INTEGRATION NOTES · REVIEWED 2026-09-22

What to check in your application

Include ambiguous and out-of-scope examples when evaluating a classifier.
Compare cost per accepted result, including retries, rather than token price alone.

Start with the example below, then test representative inputs against your own acceptance criteria.

Make a request
