## How to choose

- Template tooling and data input: Check how templates accept data and which fields they expose, since an agent must map its records onto those fields before any render can run.
- Output formats and hosting: Check which formats come back and whether the file is returned or hosted, since hosted renders may be deleted after a retention period.
- Render speed and price per render: Time a render of a full batch and multiply the price per render by the batch size, since a slow or metered render can stall an agent's whole pipeline.
- Licence to publish outputs: Read what the licence lets you publish commercially, since an agent that ships generated banners for a client needs commercial rights to the output.
