description: >-
  Stability Developer Platform rate-limits via account credit balance and per-account RPS
  thresholds. Specific HTTP RPS caps are not publicly documented; standard 429 backoff
  applies. Credit balance must remain positive to call the API.
notes: Maintain positive credit balance to avoid 402 / 429 throttling on Stable Audio calls.
