What the publisher says

From the Word Orb — English vocabulary for reader glossaries repository's README, as published. We do not edit it. Read it on GitHub

Word Orb

Stored English lexical records for reader glossaries and vocabulary tools. Word Orb serves about 162K AI-assisted English records as JSON. Optional translations cover about 14K English headwords across 47 language codes; field coverage and quality vary. The content has not been independently human-verified.

Build a glossary from stored records

The batch glossary example normalizes and deduplicates English words, reads existing records, preserves missing words and errors, and displays only fields returned by the API. It never falls back to generation or another service.

Use Node.js 18 or later and an existing Word Orb API key. No package installation is needed. Set WORDORBAPIKEY securely in your environment, then run:

node examples/batch-glossary.mjs courage wisdom resilience

The default batch size is 10 words, suitable for the free plan. Paid plans support batches of up to 50; set WORDORBBATCHSIZE=50 when your plan supports it. Output is JSON for inspection or integration into your application. Display results to users only after evaluating their suitability for your use case.

POST https://wordorb.ai/api/words/batch accepts {"words":["courage","wisdom"]} with an Authorization: Bearer ... header. Batch lookup only reads stored records. Unknown words remain missing; a stored response is not a guarantee of factual accuracy. Translation, pronunciation and other fields may be absent.

Existing JavaScript client

This repository contains the CommonJS client published as @lotd/word-orb. It does not currently expose a batch method; use the direct HTTP example above for stored-only lookups.

const { WordOrb } = require('@lotd/word-orb');
const orb = new WordOrb({
  apiKey: process.env.WORDORB_API_KEY,
  baseUrl: 'https://wordorb.ai',
});
const usage = await orb.me();
console.log({ tier: usage.tier, callsToday: usage.calls_today });

The client's word() method uses the individual lookup endpoint, whose behavior differs from stored-only batch lookup. Check the current API documentation before using it. Older examples in this repository describe earlier integrations and are not the stored-only glossary flow.

Plans

Free API keys allow 10,000 calls per day with a limit of 10 requests per minute and batches of up to 10 words. Starter is $9/month, including 150,000 calls per UTC calendar month, then $0.0006 per additional call, plus batches up to 50 and TextOrb. The included allowance resets on the first day of each UTC calendar month, separately from subscription renewal. When Starter metered billing is active, the displayed 5,000-call daily baseline does not block additional calls. Pro is $49/month with 50,000 calls per day; Scale is $149/month. See the current pricing page for full limits and terms.

Start with the word-list evaluator to check real coverage and field availability before integrating. Do not assume 47 complete dictionaries, editorial verification or complete audio coverage.

MCP

The canonical remote endpoint is https://wordorb.ai/mcp over Streamable HTTP. The existing MCP Registry identity remains io.github.nicoletterankin/orb-platform; server.json describes version 6.3.1 under that identity.

Stored-only glossary lookup

Use the lookup_words tool with an array of English headwords:

{"words":["courage","wisdom","resilience"]}
