# Plainrouter

> Plainrouter is the paid ads platform for developers and agents. It connects first-party conversion signals to governed advertising proposals and Ask approval or Full automatic Meta execution.

This is a discovery index. Follow the linked documents for integration instructions and current pricing. Arrival counting, conversion delivery, approval, and verified provider execution are separate concepts.

Do not ask for or expose underlying Meta, Google, or Plainrouter credentials.

Ask waits for approval; Full runs policy-allowed changes automatically. Rule violations are blocked and shown in the Inbox. New ads are created paused, provider writes require verification evidence, and authorization stays within the workspace and any account restriction of the credential.
