Developer Billing

OpenRouter Setup

How Developer Billing users create, fund, and connect an OpenRouter account.

Create and fund the account

  • Create or sign in to an OpenRouter account before switching a workspace to Developer Billing.
  • Add enough OpenRouter credits for model usage. OpenRouter API keys cover model costs through the OpenRouter account.
  • Create a dedicated API key for this app instead of reusing a personal development key.
  • Set a conservative key credit limit when OpenRouter offers one; that limits blast radius if the key is copied by mistake.

Save it in the app

  • Paste the OpenRouter API key into Settings > Provider Keys > OpenRouter.
  • Save the key and wait for the verification status to refresh.
  • If verification fails, confirm the key was copied completely, the key is not disabled, and the OpenRouter account has usable credits.

OpenRouter provider keys are different

  • This app's Developer Billing plan means you connect provider accounts to Topic to Video.
  • OpenRouter also has its own provider-key feature for adding upstream model-provider keys inside OpenRouter.
  • Most users of this app only need an OpenRouter API key plus OpenRouter credits, not upstream provider keys inside OpenRouter.

Security

  • Never put the key in a script, email, screenshot, shared doc, chat message, or support ticket.
  • If the key is exposed, delete it in OpenRouter and create a replacement key before saving the new value in the app.

Used for

  • Research, scripts, reviews, chat, image prompts, scene images, and thumbnails depending on the project path.
