Feature & Specification Comparison
Tools & Capabilities Breakdown
Mychem Tools (3)
query
Search MyChem.info for drugs / chemical compounds. Accepts a plain drug name ("aspirin"), an InChIKey, or a fielded query (e.g. "chembl.pref_name:aspirin", "drugbank.name:Acetylsalicylic acid"). Returns aggregated hits with cross-references to ChEMBL, DrugBank, PubChem, ChEBI, DrugCentral, etc. Use…
chem
Fetch the full aggregated annotation for a single chemical / drug by id. The id is typically an InChIKey (e.g. "BSYNRYMUTXBXSQ-UHFFFAOYSA-N"), but a DrugBank id, ChEMBL id, or other source id also works. Returns merged annotations from ChEMBL, DrugBank, PubChem, ChEBI, DrugCentral, etc., including…
metadata
Returns MyChem.info build metadata: total indexed compound count, available annotation sources (ChEMBL, DrugBank, PubChem, ChEBI, DrugCentral, FDA NDC), and their current release versions.
Mydisease Tools (3)
query
Search MyDisease.info for diseases by free-text name or fielded query. Returns matching hits, each keyed by a MONDO disease id (e.g. "MONDO:0015967") with the best-matching ontology and annotation keys. Use this to resolve a disease name to canonical ontology ids before calling the "disease" tool.…
