How this service works
Drug target and bioactivity data from ChEMBL (EMBL-EBI) — ChEMBL ID, max clinical phase, molecular properties, indication class.
Output
Returns structured ChEMBL data for the queried drug or target, including the ChEMBL ID, maximum clinical trial phase reached, molecular properties (such as molecular weight, logP, polar surface area), and therapeutic indication class sourced from the EMBL-EBI ChEMBL database.
Example use cases
Example prompt
“Can you look up the ChEMBL target data for imatinib — I need its ChEMBL ID, max clinical phase, indication class, and key molecular properties?”
Technical details
Endpoint
GEThttps://bio.memoryapi.org/x402/bio/targetsWhen to prefer
Use this endpoint when you need authoritative drug target and bioactivity data from the EMBL-EBI ChEMBL database, specifically ChEMBL IDs, clinical phase status, molecular properties, and indication class. Prefer this over PubChem (CID/SMILES) when bioactivity and clinical phase data are the primary need, and over UniProt when compound-centric rather than protein-sequence data is required.
Side effects
- Target or compound not found in ChEMBL returns empty or 404 response
- Ambiguous query matches multiple targets — may return unexpected results
- Payment not processed (x402) — endpoint returns 402 Payment Required
- Rate limiting if too many requests are made in quick succession
- Invalid query parameter format returns 400 Bad Request
