Try a model in Playground

Playground is the fastest way to confirm that your NexoRouter account, prepaid balance, and a public chat model work before you write code.

You must be signed in. Playground is an account page, not a public demo. This page does not include a product video.

Open Playground

  1. Sign in at https://nexorouter.com/en/sign-in.
  2. Open https://nexorouter.com/en/playground.
  3. If you are not signed in, NexoRouter redirects you to sign-in and then back to Playground.

Spanish Playground: https://nexorouter.com/es/playground. Spanish is the default locale, so https://nexorouter.com/playground is the same page.

What you need

  • A NexoRouter account.
  • Prepaid balance in Billing.
  • At least one active API key from Dashboard -> API Keys.
  • A publicly available chat model in the Playground model list.

Playground uses one of your active API keys. You do not paste the secret into the browser. A successful Playground message consumes prepaid balance the same way an API call does.

Send a first message

  1. Select an active API key.
  2. Select a chat model ID. The docs starter is kimi-k2.6 when it appears in the list. Copy exact catalog IDs such as gpt-5.5, gpt-5.6-luna, or grok-4.3 from Models if you want those models.
  3. Keep or edit the system message.
  4. Enter a short user prompt.
  5. Optionally set temperature and max_tokens.
  6. Send the message.

After a successful run, Playground shows the reply, token usage, and equivalent curl, Python, and JavaScript snippets.

If Send is disabled or the request fails

  • Create an active API key in Dashboard -> API Keys.
  • Select a model from the chat list. Playground only lists commercially available chat models.
  • The user prompt cannot be empty.
  • If the error is insufficient balance, add prepaid credit in Billing and retry.
  • If Playground works but local code fails, compare base URL, model ID, and Authorization: Bearer with First API call.
