开发者推出免费词典 API，基于 Wiktionary 数据且无需 API 密钥

Look up English words and access definitions, word lists, translations, and a word of the day. Responses are JSON and no API key is required.

All endpoints use HTTPS and return JSON. No API key is required. Use the quick start below to make your first request, or jump to an endpoint for its path, parameters, and examples. Requests are subject to rate limits to help protect service availability.

Make your first request with curl. No SDK or API key is required.

Uses the public Dictionary API through this site's hostname.

GET Get definitions

Retrieve definitions and meaning data for an English word.

{ "word": "happy", "meanings": [ { "partOfSpeech": "adjective", "senses": [ { "glosses": [ "feeling or showing pleasure and contentment" ] } ] } ] }

GET Search words

Retrieve a paginated list of words matching a prefix.

Retrieve translation data for a word, optionally filtered by part of speech.

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.
