A single element by symbol, number or name
API · /elements-api
Chemical Elements API
The complete periodic table as an API — all 119 chemical elements with their atomic and physical properties: atomic number and mass, category, phase, melting and boiling point, density, electron configuration, electronegativity, ionization energies and a short summary. Look up an element by symbol, atomic number or name, search and filter by category/phase/block, or fetch the whole table. Ideal for chemistry tools, education apps and science projects.

Crystallography API
Crystal structures as an API — powered by the Crystallography Open Database (COD), the open, public-domain collection of over 500,000 crystal structures of organic, inorganic, metal-organic compounds and minerals. Search the database by chemical formula (any standard casing — TiO2, Al2O3, H2O — is normalised automatically) or by free text over mineral names, titles and comments, then look up any structure to get its full crystallographic data: chemical and cell formula, space group (Hermann-Mauguin and Hall), the complete unit cell (a, b, c, alpha, beta, gamma and volume), the source publication (title, authors, journal, year, DOI) and a link to the CIF file. From quartz, calcite and diamond to anatase, corundum and diopside, it is ideal for materials science, solid-state chemistry, mineralogy, crystallography teaching and research tooling. This is a crystal-structure & materials database — distinct from molecule-property (chemistry / PubChem) and protein-structure (PDB) databases. Open data from the Crystallography Open Database (CC0 / public domain).

Chemistry API
Chemical compound data as an API, powered by NIH PubChem (>100 million compounds). Look up any compound by common name, PubChem CID or SMILES and get its molecular formula, molecular and exact mass, IUPAC name, canonical SMILES, InChI and InChIKey, plus physicochemical properties (XLogP, TPSA, formal charge, hydrogen-bond donor/acceptor counts, rotatable bonds, heavy-atom count). List a compound's synonyms and trade/registry names, or resolve a name to PubChem CIDs. Ideal for cheminformatics, lab software, education, drug-discovery tooling and scientific data pipelines.

Protein Interactions API
Protein-protein interaction networks as an API — powered by STRING, the database of known and predicted protein associations that combines evidence from laboratory experiments, curated pathway databases, gene co-expression, genomic context and automated text mining into a single confidence score, across thousands of organisms. Get a protein's top interaction partners (each with the combined confidence score and the seven evidence-channel subscores), the interaction network among any set of proteins as scored edges, and functional enrichment for a gene set — the over-represented GO terms, KEGG pathways, Pfam domains and more, each with its p-value, FDR and member genes. Pass gene symbols (TP53) or STRING/Ensembl ids, for human (default) or any species by NCBI taxon id. It is a cornerstone of systems biology — ideal for network analysis, functional genomics, pathway and bioinformatics tools. A protein-interaction-network resource — distinct from biological pathways (Reactome), curated protein complexes (Complex Portal) and Gene Ontology annotations (QuickGO). Open data from STRING (CC BY 4.0).

Polygenic Scores API
Polygenic (risk) scores as an API — powered by the NHGRI-EBI PGS Catalog, the open database of published polygenic scores: weighted combinations of genetic variants used to estimate a person's genetic predisposition to a trait or disease. Search traits by name to find their ontology ids, list every polygenic score developed for a trait, and read a score's full metadata — the reported and mapped (EFO/MONDO) traits, the number of variants in the score, the development method, genome build, the ancestry distribution of the samples it was built and evaluated on, the publication behind it (title, journal, date, PubMed id), the release date, license and a direct link to the scoring file. From breast cancer and coronary artery disease to type 2 diabetes and BMI, it is ideal for statistical genetics, genomics, risk-prediction research and bioinformatics tools. A polygenic-score / genetic-risk-prediction resource — distinct from single-variant association studies (GWAS Catalog), population allele frequencies (gnomAD) and clinical variant interpretation (ClinVar). Open data from the NHGRI-EBI PGS Catalog (CC BY 4.0).
