## Common Questions
Match user requests to endpoints in references/api-spec.lap. Key patterns:
- "List all activities?" -> GET /activities
- "List all assays?" -> GET /assays
- "List all drugs?" -> GET /drugs
- "List all efo?" -> GET /efo
- "List all hpo?" -> GET /hpo
- "List all intact?" -> GET /intact
- "List all molecules?" -> GET /molecules
- "List all proteins?" -> GET /proteins
- "List all bioassays?" -> GET /pubchem/bioassays
- "List all sids?" -> GET /pubchem/bioassays/sids
- "List all compounds?" -> GET /pubchem/compounds
- "List all substances?" -> GET /pubchem/substances
- "List all targets?" -> GET /targets
## Response Tips
- Check response schemas in references/api-spec.lap for field details
## References
- Full spec: See references/api-spec.lap for complete endpoint details, parameter tables, and response schemas
