Frequently asked questions
Everything people ask most often about pixbix. If your question is not here, we answer email within one business day.
What is a credit, and how many does a render cost?
Credits are the unit of rendering. Images and video draw on separate balances, because a poster costs milliseconds of browser time while a minute of 4K costs minutes of CPU — one shared unit would either make posters absurdly expensive or make video effectively free.
A standard poster is 1 image credit. Larger canvases and print-ready PDFs cost more. Video is priced per output second and scales with resolution, frame rate and codec, so a 15-second HD clip costs far less than the same edit at 4K60.
You never have to guess: POST to /api/v1/render/estimate and you get the exact cost back before anything runs.
What happens to my credits if a render fails?
They come back. Credits are held when a render is submitted, not spent — so a queued job cannot be started against a balance you do not have. If the render succeeds the hold is settled; if it fails or is cancelled, the exact credits are returned to the buckets they came from.
A refunded monthly allowance is still a monthly allowance and still expires at the period boundary. A refunded purchased credit is still permanent.
How is pixbix different from an AI image generator?
pixbix is a rendering engine, not a model. Your template defines the layout and the API fills in the fields, so the same input produces the same pixels today, next quarter and after ten thousand renders.
That is exactly the property generative tools cannot offer. For brand work a logo that drifts, a price in the wrong place or a legal disclaimer that quietly vanishes is not a creative choice — it is a defect.
Is test mode really free?
Test-mode keys spend no credits, and they run the real rendering pipeline rather than a mock — so what you test is what you ship. Every test render is watermarked.
They are capped per plan rather than unlimited. Costing nothing would otherwise make test mode the one route to the render fleet with no ceiling at all. You can see the allowance and what you have used on the Credits page.
Credits
Do plan credits roll over to the next month?
No. Your monthly allowance refills at the start of each billing period and unused allowance expires. A workspace on 500 a month that renders nothing still has 500 the next month, not 1,000.
Credits you purchase separately behave differently: they never expire, and they are only spent once the monthly allowance is exhausted. Spending the perishable currency first is always better for you, so that is what the system does.
API
What are the API rate limits?
Two separate limits apply. A per-minute rate limit smooths bursts, and a monthly request allowance caps total volume. Both are set by your plan, and both are visible on the Credits page in the dashboard.
Every metered response also carries X-Quota-Limit and X-Quota-Used headers, so you can track consumption without polling anything. Monthly allowances reset on the 1st, UTC.
How do I know when a video render is done?
Two ways, and you can use either. Register a webhook and we will POST to it when the render completes or fails — signed with HMAC and a timestamp, retried with backoff, and disabled automatically if the endpoint stays dead.
If you would rather not run a receiver, poll GET /api/v1/render/:id. Webhooks are a convenience over that endpoint, never a replacement for it, so polling is always a valid fallback.
Templates
Can one field change more than one thing in a template?
Yes, and this is the part most template systems do not do. A field binds to a property *path*, and it can bind to several at once — so a single "headline" input can set the headline text, scale its font size, recolour a shape and retime a clip together.
It also means you decide exactly what a caller may change. Everything you do not expose — logo, colours, safe areas, legal text — is locked in the template and cannot be altered through the API.
Billing
What happens to my workspace if a payment fails?
Nothing immediately. Your workspace keeps running and we email the owner, so a card that expired over a weekend does not take your pipeline down with it.
If it stays unresolved the workspace moves to the free plan. Your monthly allowance stops, but credits you purchased are untouched — those were paid for and are not ours to remove. Your templates and media are not deleted.
Can I get an invoice with my GST details?
Yes. Add your GSTIN and registered business address during setup or in workspace settings, and every invoice carries them. If you skipped it at signup you can add it at any time — invoices issued afterwards will include it.
Security
Do you use my designs or uploads to train anything?
No. Your templates, uploads and rendered output are yours. We process them to run the service you asked for and for nothing else — there is no model being trained on your content, because there is no model.
Where is my data stored, and can I delete it?
Content is stored on infrastructure in the region configured for your workspace, encrypted in transit and at rest. API credentials are only ever stored as SHA-256 hashes, so a database leak cannot be replayed as working keys.
You can export or delete your data at any time from settings, or by writing to us. We answer within 30 days, and sooner in practice. The privacy policy sets out the full detail, including retention periods.
