Once you have signed up for a Lexicala API account through RapidAPI system, you can start making calls. You should integrate the API into your code, which is done separately from the Lexicala API website. You can also view the requests in your browser by entering your query into the address bar.
Please refer to the documentation for instructions on how to start making calls to the Lexicala API.
The data you obtain from Lexicala API may not be stored locally (cached) for any purpose. However, if it is required for your specific needs (such as in offline cases), you are welcome to contact us directly to discuss. Together, we can better understand your needs and devise solutions how to cater to them. In most cases, you would be able to purchase the data in the form of XML or JSON (or RDF) files for direct integration into your system without Lexicala’s server calls. This option may prove to be more efficient and, sometimes, also more economical.
