Get translations Retrieve translation data for a word, optionally filtered by part of speech. Word of the day Retrieve the word-of-the-day entry. Rate limits The API enforces per-client-IP rate limits. Limits are applied separately to the general dictionary endpoints and the Word of the Day endpoint. Rate limits use a token-bucket algorithm with greedy token refill. Tokens replenish continuously over the configured one-minute interval, rather than all at once at the end of each minute. Design clients to stay within these limits. Avoid tight retry loops; if a request is rate-limited, wait before retrying. Requests may return standard HTTP error responses, including 400 for invalid requests, 404 when a resource is not found, and 500 for an unexpected server error. Endpoint details are based on the API repository's published endpoint notes. Confirm response schemas against the live service before treating examples as exhaustive.
