FAQ

$0.60, billed per call with our standard discount applied up front — and you're only charged on success.

Yes — new accounts start with free credits, so you can try Sora 2 Pro before adding a balance.

Served on a 99.9% uptime target with automatic same-kind fallback if an upstream has a hiccup.

Yes. It's drop-in OpenAI-compatible — no code changes beyond the base URL and key.

Typically 5–10 seconds per call — set the duration in the request and chain calls for longer sequences.

16:9, 9:16 and 1:1 up to 720p–1080p depending on the model, chosen per request.

Per-key rate limits you set from the console, with sensible defaults on every new key. Need more headroom? Just ask support.
