Token and API spend per run, tool call, and model, with a daily fair-use cap and anomaly flags.
Free and Pro use the platform key; Enterprise can bring your own key (BYOK) kept server-side.
Each run carries a runId; spend is rolled up by runId, tool, and model.
Enterprise supports caps; Pro surfaces HTTP 429 when fair-use limits are hit.
Any OpenAI-compatible endpoint configured via OPENAI_BASE_URL.
Near-real-time; dashboards refresh per run.
Yes. Self-serve plans cancel anytime; access continues until period end.
No. Start with email signup, then upgrade when ready.
No for Free/Pro. AI runs are included in your plan (fair use) via our platform key. Enterprise can optionally bring your own OpenAI key (BYOK) — configure it at /settings (key stays server-side only).
Pro includes about 300 AI generations/month (and a daily cap) on gpt-4o-mini. If you hit the fair-use limit, Studio returns a mock/demo result until the daily or monthly reset — or upgrade / use Enterprise BYOK for heavier volume.
Payments are processed by Waffo Pancake (merchant of record).
You receive access confirmation; fulfillment is tracked via webhook + order logs.
