# Agent Primitives

> Low-level building blocks for agents: lookalike search, technography search, and deep research. Compose them into your own GTM workflows.

<Info>
  For AI agents: read [`llms.txt`](https://docs.openfunnel.dev/llms.txt) for a full index, and [Authentication](/agent-primitives/authentication) before calling any endpoint. Base URL: `https://api.openfunnel.dev`.
</Info>

Agent Primitives are the most widely used GTM Flows exposed through APIs. Primitives are stateless data fetchers designed to be **chained inside an agent loop**, to build your own custom workflows.

## Helpers

Supporting endpoints for the primitives, country-code options, async job pollers, and company lookup. See the **Helpers** group in the sidebar.

## Pricing

See [Credits](/agent-primitives/credits) for the per-endpoint credit costs.
