Look up English headwords from stored, AI-assisted records, with translations where available. Evaluate your vocabulary before choosing a plan.
Translations span 47 language codes across a subset of the English headwords. Field and language coverage varies by word. Records have not been independently human verified; review definitions, pronunciation notation, and translations for your use case. Evaluate stored words in a batch before upgrading.
Choose a paid plan, connect your API key, and continue to secure Stripe checkout. The same key works across Word Orb, Lesson Orb, and Quiz Orb.
Stored English definitions, etymology, and IPA, with translations, audio, and age tones where available. Check the returned fields for each word.

Give your agent structured English vocabulary in JSON. Use free batch lookups to check stored coverage before integration.
Inspect the vocabulary, available age tones, and pronunciation data your robot will present. Evaluate content and coverage for the intended learners.
Use available graph connections to link vocabulary and lesson content. Check coverage for the words and tracks your platform needs.
Use lookup_words for stored-only lookup: up to 10 English headwords per batch on Free, or 50 on paid plans. Missing records stay missing.
Connect to https://wordorb.ai/mcp using a remote Streamable HTTP client that supports custom headers. Send your Word Orb API key in the Authorization: Bearer header. Client setup varies; this endpoint does not offer OAuth sign-in.
One API key. All products. Same authentication.
First, check your own vocabulary. Free supports production use with 10,000 calls/day, 10 requests/minute, and batches of 10. Paid plans use the same stored records; upgrading does not fill missing translations or guarantee accuracy.
With metered billing active, this baseline is not a daily hard cap. Choose for larger batches or request bursts, not a larger included allowance than Free.
Assurance research is separate from vocabulary API access. No certification or offline corpus license is included. View the prototype scope.
One API key works across Word Orb, Lesson Orb, and Quiz Orb. 10,000 free calls/day. No credit card. Ship to production on the free plan.
