Several images become one paginated document, sized to a page you choose.

Combine several images into a single paginated PDF at a chosen page size and orientation.

Response

The result carries your remaining balance alongside it, so you can track spend without a second call.

  "page_size": "a4",

Cost

3 credits per call, whether it is run from the site or from the API — the credential differs, the price does not. A new account starts with 20 credits.

A rejected request still costs a credit: the authorizer decrements before the tool validates. A call rejected for a missing or invalid key is free.

Parameters

Generated from the endpoint’s own validation, so this is exactly what it accepts. A body field goes at the top level; an option goes inside options.
