FAQ
Is the service suitable for large payloads?
Yes, but for very large structures it is more convenient to work in parts. This makes it easier to see the error and format the data faster.
Is it possible to use minification before sending to the API?
Yes. Minified JSON is more compact and convenient for transmission where visual readability is not needed.
