Word Ladder Generator is an API that produces puzzles where players change one word into another by altering a single letter at each step, ensuring each intermediate word is valid. This tool is designed for integration into applications, allowing developers to generate word ladder puzzles programmatically.
The API operates through a single endpoint and supports requests in JSON, XML, and YAML formats. It provides a live request feature that does not require an API key for initial testing, while application integration requires obtaining a key. Code examples are available in cURL, Node, and Python, demonstrating how to interact with the API using real parameters such as start word, end word, difficulty level, count, and image options. The service offers online availability, with a stated uptime SLA of 99.9% and usage measured in credits per call.
