      The ChemSpider Compounds API (v1) provides comprehensive access to the RSC ChemSpider chemical database,
      supporting compound filtering by name, SMILES, InChI, InChIKey, formula, molecular weight, mass, and elemental
      composition. Authenticated endpoints allow retrieval of compound records, external references, molecular images,
      and MOL files. The API also supports batch operations and chemical format conversions between SMILES, InChI,
      InChIKey, and Mol formats.

      The ChemSpider Tools API provides chemical format conversion utilities, supporting conversions between SMILES,
      InChI, InChIKey, and Mol file formats. It also includes InChIKey validation. The tools are useful for
      cheminformatics pipelines that need to normalize chemical identifiers across different format conventions.
