# WheelBlend
> WheelBlend is an AI wheel visualizer web app that lets builders upload car and wheel photos, generate realistic wheel swaps in seconds, compare options, and export/share results.

WheelBlend is built for fast visual decision-making before buying wheels or wraps. The core product flow is linear by design: upload assets, generate AI previews, compare variants, and export or share. It is free to start, with paid plans and add-on credits for higher usage and advanced workflows.

## Mission and Product Goals
- Deliver the fastest path from "idea" to realistic wheel preview with minimal manual editing.
- Help users test fitment, style, finish, and stance before purchasing real parts.
- Support experimentation: users should be able to try many combinations in one session.
- Keep uploads private by default while enabling optional sharing and community publishing.
- Maintain a free entry point, with paid expansion for more renders, collaboration, and API usage.

## Primary Users
- Car enthusiasts and builders planning wheel changes.
- Custom shops and detailers producing approval visuals for customers.
- Wheel brands, retailers, and marketplaces that need catalog, lead, API, or embedded visualizer workflows.
- Content creators producing before/after wheel concepts for social, forums, and client previews.

## Public API Endpoints (Programmatic Integration)
- [`POST /api/v1/uploads`](/api/v1/uploads): Creates short-lived signed upload URLs for car/wheel assets.
- [`POST /api/v1/renders`](/api/v1/renders): Queues async render generation with model, quality, and controls. Public auth is Bearer-only; hidden compatibility inputs are not part of `v1`.
- [`GET /api/v1/renders/{id}`](/api/v1/renders): Polls async render state and returns refreshed signed result URLs.
- [`GET /api/v1/balance`](/api/v1/balance): Reads API wallet balance.

## Product Behavior and Constraints
- File inputs: car + wheel images, PNG/JPEG/WebP supported, size limits enforced.
- Render flow: validate -> upload/sign -> queue -> worker executes mask/perspective prep -> generate -> persist -> sign result URLs.
- Public API contract is `/api/v1` only; legacy non-`/v1` API routes are internal/mobile/dashboard-only.
- API render jobs retry transient worker/provider failures with bounded backoff; webhook retries are scheduled separately and signed with a per-key `webhookSecret`.
- Performance profile: fresh renders usually around 30s; cached asset flows can be faster.
- Quota model: free lifetime credits, paid monthly plan quotas, optional credit packs, separate API wallet billing.
- Privacy model: uploads are private by default; sharing/community publication is opt-in.
- Access model: most dashboard routes require authentication; admin/marketing routes require allowlisted admins.

## SEO and AI Discovery Notes
- The sitemap includes the homepage, guides, use cases, API docs, pricing, status, changelog, press, privacy, and terms.
- `/_next/image` optimizer URLs and dashboard routes are marked noindex; real public image files are allowed to be indexed when useful for Google Images and visual discovery.
- The primary SEO hub is `/guides/try-wheels-on-your-car`; it links onward to related guides and use-case pages.
