How do I add job and company data to the AI agent I sell?

To add job and company data to the AI agent you sell, give it TheirStack's API or MCP server as one of its tools. Your agent then searches companies by the roles they hire and the technologies they run, and looks up any company by its domain, on behalf of each of your users.

What can an AI SDR do with job and technology data?

An AI SDR built on TheirStack data can find companies hiring the roles your users sell to, read which technologies each one runs, and write its first email around a posting it just found. A webhook on a saved search tells the agent the moment a new matching job is posted.

How are AI agent requests to TheirStack charged?

Each request an AI agent makes through the TheirStack MCP server costs the same API credits as the equivalent API call. A job search costs the same through MCP as through the REST API.

Can I build my own AI agent on the TheirStack API?

Yes, the TheirStack REST API gives an agent the same job, company and technology searches as the MCP server, for agents you build and host yourself. Authenticate with an API key and call the endpoints from your agent's tools.

How job data for your AI agents works

TheirStack gives the AI agents you build and sell job, company and technology data as tools over MCP, so they find the right companies for your users and research each one, while you keep the API key on your server and see what every request costs.
