# Market map of a category: an agent recipe

Lists the companies in one category with domain, founding year, headcount and a one-line description, grouped by segment.

## Prompt

Use looot to map the AI note-taking vendors: list 40 companies with domain, founding year, headcount and a one-line description, grouped by segment. 1. Set up https://looot.ai/skill.md. 2. Connect my Supabase and create the table market_map. 3. Upsert on a natural key and never overwrite my edits. 4. Store source, endpoint, cost and fetched_at on every row. 5. Show any price over one cent first and stop at my daily budget. 6. Skip rows that are already there. 7. Report rows added, rows changed and total cost.

## Steps and providers

- List the companies: thecompaniesapi, coresignal. 1 search per company.
- Add company facts: diffbot, coresignal, people-data-labs. 1 lookup per company.
- Write a one-line description: exa. 1 search per company.
