Best for
  • Developers and researchers needing quick EVM address labels
  • AI assistants that interact with the Ethereum ecosystem
  • Users who want access to public dataset
  • Drug discovery and computational chemistry researchers
  • Bioinformatics teams needing ChEMBL data through AI assistants
  • Developers comfortable with Node.js or Docker
Not for
  • Scenarios requiring real-time or dynamic label updates
  • Users needing non-public or proprietary address data
  • Users requiring advanced analytics or complex queries
  • Production settings requiring official ChEMBL support (this is unofficial)
  • Users without a Node.js or Docker environment
  • General database tasks unrelated to ChEMBL
Required permissions
  • No API key or authentication required
  • Only uses public data
  • Requires network access to fetch the dataset
  • Outbound network access to https://www.ebi.ac.uk/chembl/api/data
  • Read-only access to public API data; no authentication credentials required
Risks and side effects
  • Data may be incomplete or inaccurate
  • Dataset may not be updated in real-time
  • Labels may not reflect the latest state
  • Unofficial project with license marked NOASSERTION (README claims MIT); verify licensing yourself
  • Data accuracy depends on the ChEMBL REST API and the server's parsing may contain defects
  • 30-second request timeouts may constrain large batch queries
  • README inconsistency on tool count (22 vs 27) raises documentation reliability concerns
