The ECHO marketplace is where creative professionals list their work and buyers discover the right talent for their projects. Listings are organized by creative discipline, so whether you need a graphic designer, a photographer, or a 3D artist, you can navigate directly to relevant offerings without sifting through unrelated content.

​
How the marketplace is organized

Every listing on ECHO belongs to one of nine creative categories. Categories have both a display name and a URL-friendly slug used throughout the API and routing layer.

Item types

Creators can publish two types of listings depending on the nature of their work: PRODUCT — A tangible deliverable. Products represent a defined output that a buyer receives, such as a digital illustration, a photograph, or a design asset. SERVICE — A professional engagement. Services are tied to a delivery timeline (delivery_duration in days) and describe what the creator will do, how long it will take, and what the buyer can expect to receive. Each service can include a cover image and a detailed description.
Services can also be linked to portfolio projects as examples of past work. See Portfolio Projects for details.

​
Publishing a listing

Creators publish listings by providing a small set of core fields that apply to both products and services. 
{
  "title": "Brand identity design",
  "description": "Complete brand identity package including logo, color palette, and typography guide.",
  "base_price": 450.00,
  "item_type": "SERVICE",
  "category_id": 1
}
For services, additional fields describe the engagement: 
{
  "name": "Brand identity design",
  "description": "Complete brand identity package...",
  "delivery_duration": 14,
  "category": "graphic-design",
  "cover_image_url": "/uploads/covers/brand-identity.jpg"
}
Set a clear delivery_duration on service listings. Buyers weigh turnaround time heavily when choosing between creators for the same category.

​
Discovering listings

Buyers can browse the marketplace by category, viewing all active listings within a discipline. From any listing, buyers can navigate to the creator’s public profile to see the full picture of their work.

​
Creator profiles

A creator’s public profile displays everything a buyer needs to evaluate fit:
  • Avatar and banner image
  • Bio and location
  • Social links
  • All published services and products
  • Portfolio projects (linked to specific services as examples of past work)

​
Following creators

Buyers can follow creators they want to stay updated on. Following a creator is a one-tap action; the relationship is stored as a follower_id / following_id pair and can be reversed at any time.
The follow system is lightweight — it records the relationship but does not currently drive notifications or a curated feed. Use it to bookmark creators whose work you want to revisit.
