- At least `molecule` or `target` is required.
- `molecule` — molecule name or ChEMBL id (`CHEMBL25`). Names resolve via ChEMBL search. Look up PubChem names with https://skills.duaer.com/compounds.md.
- `target` — optional. Target name, gene symbol, or ChEMBL id. Alone, returns activities for that target. With `molecule`, filters both. Look up gene–disease targets with https://skills.duaer.com/targets.md.
- `limit` — optional. From 1 to 20. Default 10. Results prefer higher pChEMBL values.

## Result

Each item includes `source`, `title`, `url`, and `summary`, plus the fields named on this skill.

## Credits

One successful search uses 1 credit.
An empty search, a failed search, a compound that matches nothing, or no remaining credits uses 0.
No remaining credits returns 402 and does not search.
A missing key returns 401.
