A simple Python wrapper around the ChemSpider Web Services.

Project Description

ChemSpiPy provides a way to interact with ChemSpider in Python. It allows chemical searches, chemical file downloads, depiction and retrieval of chemical properties:

>>> from chemspipy import ChemSpider
>>> cs = ChemSpider('<YOUR-SECURITY-TOKEN>')
>>> c1 = cs.get_compound(236)  # Specify compound by ChemSpider ID
>>> c2 ='benzene')  # Search using name, SMILES, InChI, InChIKey, etc.


Install ChemSpiPy using pip:

pip install chemspipy

Alternatively, try one of the other installation options.


Full documentation is available at

The general documentation for the ChemSpider API is also a useful resource.
