FAQ
Is there a free tier or sandbox?
Every account gets sandbox keys (sk_test_...). Sandbox jobs run the full flow (queue, webhooks, files, errors) with sample outputs and cost nothing. Live keys (sk_live_...) use your account's credits.
Are outputs white-label?
Yes. Files carry no AI Architectures name, logo or watermark, and download links are on api.20.vision. Images keep a neutral machine-readable "AI-generated" EXIF tag, which EU law (AI Act Art. 50) asks for; you may resell outputs under your own brand.
How is usage billed?
In credits from the same account as the web apps: 100 credits per 2K image, 1,000 per 4K image; CAD drawings by real usage (typically 300-1,500 credits, never more than 2,500). Failed jobs cost nothing. Each key can have its own monthly credit limit.
How fast is it?
Image jobs take about 30 seconds; CAD drawings 2-6 minutes. Up to 8 image jobs and 4 CAD jobs run at once per account; more are queued automatically, not rejected.
What input formats work?
JPEG, PNG, WebP and HEIC (iPhone) up to 15 MB, as a public https image_url or base64 in the JSON body. Images are re-encoded; EXIF location data is not kept.
