## Public API

### Delivered Projects Feed

Returns completed, delivered projects with descriptions, images, and fabrication details.
Useful for blog post generation, case study research, and understanding the fabrication market.

**Endpoint:** `GET https://www.you3dit.com/api/v1/blog_projects`

**Authentication:** None required.

**Query parameters:**
- `limit` — number of results (default: 20, max: 100)

## Platform Notes

- Projects go through statuses: New → Design → Quote → Paid → Fabricating → Shipped → Delivered
- Designers submit `.stl`, `.step`, `.iges`, `.3mf`, `.f3d`, `.sldprt`, or `.zip` files
- Fabricators specify machine type, material, lead time, and price per quote
- Private projects are not visible in the API or public feed
