create.new_instrumental
Submit an instrumental generation request.
Returns immediately with status: processing. Use the matching GET to
poll for completion, or supply a callback_url to receive a webhook.
Instrumentals (no vocals) are generated from either a text prompt or a
reference track URL. Set n_variations (1-3) for how many variations to
produce — each appears as a separate entry in outputs when the operation
is ready.
Credits cost: 3 per variation (so n_variations: 2 costs 6).
Insufficient credits returns 402 — see errors.

Optional HTTPS URL we'll POST the final response to when the operation reaches ready or failed. Polling remains the canonical source of truth; webhooks are a best-effort latency optimisation.
