# Use Interchange

> Operate Interchange to buy media, sell inventory, and manage the work around each transaction.

Interchange documentation starts with what you are trying to accomplish. You
do not need to choose an API, protocol, or account model before finding the
right workflow.

## Documentation follows the job

Buyer and seller account types determine which actions and data you can
access. They do not create separate products or separate documentation sites.
The navigation groups account-specific workflows beneath the job they support,
while shared concepts and platform behavior have one canonical explanation.

If you are troubleshooting a live workflow, start from the relevant buying or
selling section. If you are writing code or connecting an AI agent, switch to
**Build with Interchange**.
