In addition to the described data-focused web services, a utility web service that provides RESTful access to commonly used cheminformatic methods has been released. These web services have been developed under the name 'ChEMBL Beaker' and provide users with access chemical property calculators (e.g. molecular weight), structure format converters (e.g. molfile to SMILES) and a structure standardiser. The methods being exposed by this service are providing RESTful interface to the RDKit cheminformatics library. These services also provide access to methods that extract chemical information from images. The OSRA library is used to expose this functionality. Online documentation is available.
