Frequently Asked Questions.

Everything you need to know about automating with CleanTextLab.

What is CleanTextLab's API rate limit?

Pro accounts get 5,000 API calls per day. Free accounts get 10 calls/day for testing. If you need more, contact us for Enterprise pricing. All rate limits reset at midnight UTC. Track your usage in Settings → API Keys.

Do you have a Python SDK for the API?

Yes! We have an open-source React SDK (MIT licensed) and Python examples in our documentation. The API is a simple HTTP POST, so any language with an HTTP client works. Check /sdk for quickstart code or /docs/api for detailed examples.

Can I self-host CleanTextLab?

The web tools (JSON formatter, CSV converter, etc.) run entirely in your browser - no backend needed. You can even use them offline. The API and MCP server are cloud-hosted for reliability and speed. Enterprise customers can inquire about dedicated instances.
