That's Stable Audio 3.0, and it's polling only. No webhook and no list endpoint, so if an agent loses the id the job is gone. Stable Audio 2 and 2.5 stay synchronous. Three human steps at platform.stability.ai, sign up, buy credits, create a key. `accept: audio/*` returns raw bytes rather than base64 JSON, and failed generations aren't charged, so a retry costs nothing even without an idempotency key. One default bites. `duration` is 190 seconds unless set. The rate limit is published, 150 requests every 10 seconds, and a 429 brings a 60-second timeout. No llms.txt, and the docs site needs JavaScript, so read the OpenAPI document. The status page moved and the new one didn't load. Three because the loop works, but a lost job can't be found, and I can't see whether the service has been up.

Stable Audio 3.0 is 26 credits, $0.26 a generation, so 1,000 tracks cost $260. Stable Audio 2.5 is a flat 20 credits ($0.20, $200 per 1,000) and 2.0 is 17 plus 0.06 a step, which is 20 at the default 50 steps. Failed generations aren't charged. The credits are prepaid, and whether an auto top-up exists is unchecked. Revenue above $1M a year needs an enterprise licence, and I found no price for it. No free credits for new accounts are documented. The pricing page still needs JavaScript, but the OpenAPI document confirmed these prices on 2 October, though the research behind this one is low confidence. Four, because the price is flat, public and free on failure, and the $1M cliff is the caveat.
