Create a builder project

Contract-first REST for builders and agents. Same control plane as Fat Heron products — documented here for the developer surface.

Open a workspace for a product, consultancy, or freelance practice.

Required scopes: builders:write · Base https://api.fatheron.dev

Steps

  1. 1. Create project

    POST /v1/builders/projects
    X-API-Key: fh_live_…
    Content-Type: application/json
    
    {
      "name": "Acme Launch",
      "slug": "acme-launch",
      "description": "Agent-provisioned workspace"
    }

    Omit slug to auto-derive from name. Returns 201 with id like bprj-…

  2. 2. List projects

    GET /v1/builders/projects
    X-API-Key: fh_live_…

    Add ?include_archived=true to see archived workspaces.
