> ## Agent Instructions
> Leap's API is at https://api.tryleap.ai. Send the key in the x-api-key header or as Authorization: Bearer; keys start with leap_.
> Take model IDs and input schemas from GET /v1/models/{creator}/{name}, or from https://api.tryleap.ai/v1/public/models without a key. Never guess an input field: unknown fields are a 400.
> Model inputs take uploaded file IDs (file_...), never URLs.
> To give a coding agent the whole API, install the Leap skill: curl -fsSL https://www.tryleap.ai/install.sh | sh
> The full OpenAPI 3.1 spec is at https://www.tryleap.ai/docs/openapi.json.

# Keep an output as a file

> Turns an image output of a succeeded generation into a file of your workspace, so you can pass its ID to the next run without downloading and uploading it. Calling it again returns the same file. Other outputs answer `400`.

Needs an API key with the `generations:write` scope.
