POST /api/v1/runs
Run a line of steps on one file — a recipe saved on the Workbench, or one written inline.
Same rules as the Workbench: a step in the wrong place, an option a skill does not have, or a paid skill the account cannot afford is refused before anything is charged. Each skill step is charged as it starts and refunded if it fails.
There is no list endpoint. Start with POST, read one back with GET /api/v1/runs/{id}.
Workbench and saved recipes drop unknown options. The API does not — an unknown option is an error.
See Recipes for the six catalogue lines.
