    Codemorphis API

    For automation and integrations use the REST API. Every request requires an API key in the X-API-Key header; the API has no translation limit.

    curl -X POST https://YOUR-HOST/api/translate/racket-to-java \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"code": "(define (sq x) (* x x))", "javaVersion": 11}'
    • POST /api/translate/racket-to-java
    • POST /api/translate/java-to-racket
    • Response: JSON with a result field and a list of diagnostics
    • Missing or wrong key: 401

    The website is free

    You can use the translator on this page without an account or a key. To keep it fast for everyone, it is limited to one translation per minute per IP address.

    Need more? Use the API — you get a key from the service administrator.
