Blng

aid: blng
name: Blng
description: BLNG is an AI-driven creative suite for the jewelry industry, giving jewelers, designers, brands, and retailers
  tools to explore, refine, and present designs fast and without compromise. Its Design product turns sketches, doodles, photos,
  illustrations, or text prompts into photorealistic renderings on web and iOS; Studio transforms CAD models into market-ready
  marketing photos and videos at scale; and Retail enables live, made-to-order design in-store. BLNG is a Speedinvest portfolio
  company. BLNG publishes no developer program, but the web application is backed by three first-party REST APIs whose OpenAPI
  definitions are served publicly and unauthenticated behind Swagger UI on its own hosts — a Journey API for design journeys,
  prompts, image assets and 3D model generation, a User API for users, workspaces, invitations, organizations and subscriptions,
  and a Billing API for Stripe-backed products, checkout and subscription webhooks. All three authenticate with AWS Cognito
  bearer tokens issued at auth.app.blng.ai.

  note: Round 1 recorded "no public developer API". That was wrong. STEP 0b contract discovery on the API hosts named in the
    application's own Content-Security-Policy found three real, public, unauthenticated OpenAPI definitions served behind
    Swagger UI at journeys.blng.ai, users.blng.ai and billing.blng.ai — 88 operations and 80 schemas. BLNG still publishes
    no developer program, no SDK, no MCP server and no agent card.
