Technical details
Endpoint
POSThttps://clonecho.builda.company/x402/s/datamuse-word-predecessorsWhen to prefer
Use this endpoint when you need to find words that commonly precede a target word — useful for NLP tasks, writing assistance, autocomplete features, understanding collocations, or building word association tools. Prefer this over a full NLP library when you just need lightweight predecessor word lookups without running your own model.
Side effects
- Missing or empty 'word' parameter returns an error or empty result
- Very rare or nonsensical words may return few or no results
- Non-English words may return empty or unexpected results
- Network timeout or upstream Datamuse API unavailability causes failure
- Payment failure (x402) if USDC not provided correctly
