Introduction

This guide covers our HTTP REST endpoints alongside streaming and realtime interfaces used to fold protein sequences, retrieve structural properties, and orchestrate workflows and agents. You can call the API from any environment that can make HTTPS requests, or use our first-class SDKs for Python and JavaScript for a simpler, typed client experience.

Authentication

You can create an API key in the Fastfold dashboard. Once you have an API key, you can use it to authenticate requests to the API.

API key authentication is done via the Authorization header.

Authorization: Bearer $FASTFOLD_API_KEY

Remember to keep your API key secure, as anyone with your API key can make requests on your behalf.

Next, explore the available endpoints and how to use them.

Quota Limits

All API requests are subject to quota limits. You can view your quota limits in the Usage dashboard.

If you exceed your quota limits, you will receive a 429 error. While on beta, you can upgrade your quota limits by contacting us at hello@fastfold.ai.

Next steps

Now that you're authenticated and know about quota limits, you can start using the API.
