What's the largest payload I can make in one call?

On both our Community and Professional tiers, you can process up to 250KB in one request of text input.

File processing is also available on both our Community and Professional tier and will come with limitations to the payload (file size) depending on the file type. For text -based file types such as TXT, JSON, CSV, XML & CSV files, the file size limit is 250kb. Any image-based files and audio-based files such as PDF, WAV & MP3, the file size limit is 10mb.
