Endpoint
POSThttps://clonecho.builda.company/x402/s/datamuse-predecessorsWhen to prefer
Choose this endpoint when you need to find words that typically appear immediately before a specific word — useful for writing assistance, NLP feature engineering, collocation research, or discovering idiomatic phrases. Prefer this over a general thesaurus when you specifically need predecessor collocations rather than synonyms, antonyms, or successors.
Side effects
- Empty result array if the word has no known common predecessors in the corpus
- No results for rare, coined, or misspelled words
- HTTP 402 if payment is not provided or fails
- Unexpected results if a multi-word phrase is passed instead of a single word
