Create a OpenRouter API key and use it with Aria, agents and the OpenRouter workflow nodes.

≈ 2 min Extension Web app JWT
  • An OpenRouter account with credit. Some models are free but rate-limited.
Method Use it when
Aria & agents Recommended Chat with Aria or an agent on OpenRouter models. The key is kept in Settings › Providers.
Workflow nodes Use Chat OpenRouter in a workflow. The key is a saved credential.
  1. Create a key. On OpenRouter, open Keys, click Create Key and copy it. It starts with sk-or-.
  2. Open Settings › Providers and click + Add provider.
  3. Pick OpenRouter as the Provider, give it a Label and paste the key into API key.
  4. Type the Model id, then click Add.
  5. Optionally click Set as default, so Aria and agents set to Same as Aria use it.
  • A 401, “invalid API key” or “Incorrect API key” error. The key was mistyped, revoked, or belongs to another account. Create a new key and update the credential (or the provider in Settings › Providers).
  • A 429 or “quota” error. The account is out of credit or over its rate limit. Add credit or wait, then run again.
  • An embeddings node fails with 401 while a chat node with the same key works. The credential is a Bearer Token. Embeddings nodes pass the value to the provider as it is, so use a JWT credential that holds only the key.
  • A 402 “insufficient credits” error on a short prompt. The request reserves credit for the longest possible answer. Lower Max Tokens in the node’s Options, or Max output tokens in the provider, or add credit.
