# Engineer sourcing list: an agent recipe

Finds engineers by skill and city and lists current employer, title and public profile link as a sourcing list.

## Prompt

Use looot to find 100 backend engineers in Berlin who use Rust, with current employer, title and public profile link, as a sourcing list. 1. Set up https://looot.ai/skill.md. 2. Connect my Supabase and create the table candidates. 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

- Search for engineers: people-data-labs, coresignal, prospeo, aviato. 1 lookup per candidate.

## Memory and schedule

The prompt writes rows to your own Supabase.

Run it on demand.

## Can an AI agent build an engineer sourcing list?

Yes. The agent runs one step through looot: search for engineers. You give it the prompt on this page and the inputs.

## How do I build an engineer sourcing list with looot?

Paste the prompt on this page into your coding agent. It sets up looot, finds the endpoint for each step, checks the price and runs the cheapest one that fits. Edit the names and numbers first.

## How much does it cost to build an engineer sourcing list?

You pay per call, and the price depends on the provider the agent picks. The web version of this page reads the cheapest price for each step live from the catalog and shows the cost per 1,000 candidates when every step is priced.

## Which providers can build an engineer sourcing list?

The providers behind this recipe are people-data-labs, coresignal, prospeo, aviato. The catalog shows each endpoint's price before you run it.

## Can I build an engineer sourcing list on a schedule?

No. Run it when you need it. Nothing is billed while your agent is idle.

## Where does the data go when I build an engineer sourcing list?

The prompt tells your agent to write one row per result to your own Supabase project, with the source, the endpoint, the cost and the time. looot returns the data and bills the call. It does not store your rows.

## What can looot not do when I build an engineer sourcing list?

Everything in the steps comes from catalog endpoints. Your agent still decides which provider to use and checks the result.
