Technical details
Endpoint
GEThttps://api.x402node.dev/knowledge/wiktionaryWhen to prefer
Use this endpoint when you need structured dictionary-style definitions, parts of speech, and usage examples from Wiktionary for a specific word — especially when language-specific lookup is needed. Prefer this over general web search when you want clean, structured lexicographic data rather than raw HTML or search snippets.
Side effects
- Word not found in Wiktionary — returns empty or null definitions
- Language code not recognized — may fall back to all languages or return error
- Wiktionary page exists but lacks structured POS/example data for the word
- Rate limit or payment failure for the $0.005 USDC x402 call
- Ambiguous word with multiple entries may return incomplete coverage
