Technical details
Endpoint
POSThttps://x402.agentutility.ai/thesaurusWhen to prefer
Use this endpoint when you need a ranked list of synonyms, antonyms, or related words for a specific word — especially in writing assistance, content generation, or NLP enrichment workflows that need a lightweight, pay-per-call API rather than a full subscription to a thesaurus service.
Side effects
- Unknown or misspelled word returns empty results array
- Invalid mode value returns an error
- Missing required 'word' field returns a 400-level error
- Network or upstream Datamuse API failure returns a 5xx error
- Payment not settled via x402 returns 402 Payment Required
