From your message: “Add a pricing table and say what happens when the pool is empty.”

Rate limits

Every workspace shares one credit pool. A credit is one model call, whatever
the model.

Plan	Included	Overage
Free	200 / month	blocked
Team	5,000 / month	$0.004 / credit
Scale	metered	$0.003 / credit

When you run out

Requests return 429 with a Retry-After header.
The workspace owner gets one email — not one per request.
Nothing is deleted; the pool refills on the first of the month.

Batch endpoints spend from the same pool at half rate.

status="ready" · kind="svg" · 2 revisions: Preview draws the SVG as an image (a data: URL in an img, so model-written scripts never run — the price is that currentColor cannot reach the page palette either, which is why the artifact carries its own colors), v2 adds the week labels v1 lacked; download extension .svg, MIME image/svg+xml
