Code-Based / API Access

Access molecular data, simulate, and analyze protein-ligand interactions at scale with a powerful drug discovery API built for computational chemists.

  • Gather data: Query major chemical and biological databases like PDB, ChEMBL, PubChem, and UniProt. Automate structure retrieval, annotations, and internal data enrichment.
  • Discovery: Programmatically extract molecules from literature and patents, run similarity searches, and analyze PDF data with structure-aware parsing.
  • Scale: Run high-throughput docking and property calculations using state-of-the-art AI tools. Optimize lead compounds with code-based precision.

An AI Assistant is only as good as its tools

FAQ

What algorithms does Balto use for molecular modeling?

Balto uses Deep Origin’s proprietary algorithms for docking, properties predictions and finding novel pockets. Balto also relies on a few open-source tools and databases such as MolStar, PDB and ChEMBL.

How do you deal with hallucinations?

Although Balto hallucinations are very rare, it is advisable to verify the information that Balto provides.

What is included in the free trial?

Free trial includes 50 credits. These many credits are enough to:
Dock and find poses for up to 410 molecules
Predict up to 910 molecular properties
Find novel pockets for up to 10 proteins
Analyze up to 305 pages of PDF documents

You can also explore countless free actions such as:
