Playground

Playground sends the same inference payload your application would send and shows the route Relay actually selected. Check a configured model or Group before integrating a client.

Dashboard

1. Open Playground.
2. Choose a group or provider/model in Target.
3. Edit Request body.
4. Click Send Request.
5. Inspect the response, selected model, wait time, and usage.
6. Click Copy beside the curl command.

Hosted requests can use your signed-in browser session when the key field is empty. To test a particular User API key, enter that key first. A copied curl command does not include your login cookie.

The shared UI calls the field Relay API Key. Hosted users must enter a User API key from Account → API keys. Self-hosted Relay users enter their deployment's inference token.

API

Use an appropriately scoped API key for these requests.

Send a request

curl -X POST 'https://api.anchorshell.com/v1/chat/completions' \
  -H 'Authorization: Bearer <API_KEY>' \
  -H 'Content-Type: application/json' \
  -d '{
  "model": "agentic",
  "messages": [
    {
      "role": "user",
      "content": "Hello"
    }
  ]
}'

Response — 200 OK

Example non-streaming response (selected fields). Content, model, and usage depend on the selected provider.

{
  "id": "<COMPLETION_ID>",
  "object": "chat.completion",
  "model": "gpt-5-mini",
  "choices": [
    {
      "index": 0,
      "message": {
        "role": "assistant",
        "content": "Relay waits for the preferred model before considering fallback."
      },
      "finish_reason": "stop"
    }
  ]
}

Use a Group you configured. A copied command containing a key is a secret: keep it private. See Self-hosted for local URLs and tokens.
