Technical details
Endpoint
POSThttps://clonecho.builda.company/x402/s/datamuse-antonymsWhen to prefer
Use this endpoint when you need antonyms specifically for a single word and want a simple, pay-per-call API backed by the Datamuse lexical database. Prefer this over building your own NLP pipeline or using a thesaurus API that bundles synonyms, antonyms, and other relations together when you only need antonym data.
Side effects
- Word not found or no antonyms exist — returns empty array
- Missing or malformed 'word' parameter — may return error or empty result
- Rate limiting or payment failure — returns 402 Payment Required
- Network timeout or service unavailability — returns 5xx error
