Our HTTP API is easy to use - see the documentation here:
Some facts about our API plans:
- Contact us if you're interested in a long-term subscription. We offer a 20% discount for yearly upfront payments.
- While the maximum number of characters per request is limited to 40,000 (talk to us if you need more), we expect your requests to be no more than 5,000 characters on average.
- We assume you're not going to send your requests in batches. Thus there's a limit of 100,000 characters per 60 seconds - talk to us if you need more.
- This API cannot be used to publicly offer a service that is a competitor to LanguageTool Plus. You are, of course, free to use it to enhance your existing apps, tools, and websites.
- The version of LanguageTool Plus will be updated from time to time, so results might change over time for a given text.
- If any of these limitations pose a problem for you, just contact us at , and we'll make you an individual offer.
- Our plans can be canceled any month by contacting us via email.
