By accessing or using the Word Orb API ("Service"), you agree to be bound by these Terms. If you do not agree, do not use the Service. "You" refers to any individual or entity using the API.
Word Orb provides stored, AI-assisted English vocabulary records, with translations and other fields where available, alongside lesson, quiz, and text endpoints. Translation coverage spans a subset of the English headwords and varies by language. Records are not independently human verified. Evaluate the returned fields for your intended use.
Access requires an API key (prefixed wo_). Each account receives one key. You are responsible for key security. Do not share, publish, or embed keys in client-side code. Compromised keys should be regenerated immediately via /api/keys/regenerate.
