Overview
database-lookup is an open-source data skill for Claude Code and compatible agents, published by K-Dense-AI. Its author describes it as: “Query documented public database APIs with explicit endpoints, filters, pagination, and provenance. Use when a scientific, regulatory, financial, or other database-backed fact must be retrieved reproducibly from a nam…”. The project has 40k stars on GitHub and is available under the MIT license. Add it to your setup with `git clone https://github.com/K-Dense-AI/scientific-agent-skills ~/.claude/skills/database-lookup`.
What database-lookup does
This skill catalogs 78 public databases with documented API access patterns. Your job is to turn the user's intent into a reproducible retrieval: select the authoritative database(s), make bounded and rate-limited API calls, verify counts when completeness matters, and return results with enough provenance that another agent or human can repeat the lookup.

Frequently asked questions
- What does database-lookup do?
- Query documented public database APIs with explicit endpoints, filters, pagination, and provenance. Use when a scientific, regulatory, financial, or other database-backed fact must be retrieved reproducibly from a named source rather than inferred from general knowledge.
- How do I install database-lookup?
- Run git clone https://github.com/K-Dense-AI/scientific-agent-skills ~/.claude/skills/database-lookup in your agent, then reload your skills. Review the source at https://github.com/K-Dense-AI/scientific-agent-skills before installing.
- Is database-lookup free to use?
- Yes. database-lookup is free and open source under the MIT license, so you can read, run, and adapt it within that license's terms.
- Where does database-lookup come from?
- database-lookup ships inside K-Dense-AI/scientific-agent-skills, a repository that contains 42 catalogued skills in total. The repository's 40,410 GitHub stars apply to that whole collection, not to this skill on its own.
