        "note": "COD (the Crystallography Open Database) is the open, public-domain collection of crystal structures of organic, inorganic, metal-organic compounds and minerals — over 500,000 entries, each with unit-cell parameters, a space group, a chemical formula and the publication it came from. /v1/search?formula=TiO2 = find structures by chemical formula (any standard casing — TiO2, Al2O3, H2O — is normalised to COD's alphabetical form), or /v1/search?text=quartz = free-text search over mineral names, titles and comments; both return each match's COD id (e.g. 2100348), formula, mineral, space group and year. /v1/structure?id=2100348 = a single structure's crystallographic data — chemical and cell formula, space group (Hermann-Mauguin and Hall), full unit cell (a, b, c, alpha, beta, gamma and volume), the source publication (title, authors, journal, year, DOI) and links to the CIF file. Get a COD id from /v1/search. Data from the Crystallography Open Database (CC0 / public domain). A crystal-structure & materials database — distinct from molecule-property (chemistry/PubChem), protein-structure (PDB) and sequence databases.
