## Give this to your agent

```text
Use my connected Agentik MCP server for this job: market sizing.

Size a market. First ask me for the product, the country, the target companies and the buyer’s title.

Count target companies with icypeas/count-companies and buyers with leadsforge/count-people. Read population and GDP with world-bank/indicator. Size search demand for the solution with dataforseo/google-ads-search-volume. Find typical prices in market reports with exa/search.

Finish with TAM, SAM and SOM, each with its formula, inputs and sources, a bottom-up and a top-down estimate, and the assumptions that move the result most.

Before running anything, inspect each tool with inspect_tool, ask me for any input you don’t have instead of inventing it, and tell me the total price. Wait for my go. At the end, tell me what Agentik charged.
