The Fold API provided by allows you to generate protein structures from both proprietary and open source models.

You can list the available models with /fold/models and view a model summary (including usage, citations, limitations and more) with /fold/model/{model_id}.

Currently, we support the following models: - ESMFold: Open-sourced ESMFold model. - AlphaFold2: Open-sourced implementation using colabfold.
