Agent Lab · AI Gateway status

This page asks our hosted AI Gateway whether it is ready, straight from your browser, with no sign-in. It asks again every minute.

What each state means

## What you see, and what to do

- ### Operational
  The Gateway answered and said it is ready to take model calls.
  **What to do** If your call still fails, the cause is most likely that request, its key or a limit: look up the code in the response in [Gateway error codes](https://agentlab.cresclab.com/docs/en/gateway/errors), or open the request under **AI Gateway › Usage**.
- ### Not serving right now
  The Gateway answered but said it cannot take model calls yet, for example while it starts or reloads its configuration. Calls in the meantime can get a 503 `gateway_unavailable`.
  **What to do** This is on our side. Wait and retry; the OpenAI and Anthropic SDKs retry on their own. If it stays like this for more than a few minutes, write to [info@cresclab.com](mailto:info@cresclab.com) with the time you saw it.
- ### Unreachable
  Your browser got no answer from the Gateway within 10 seconds. The Gateway may be down, or your network, company firewall or proxy may be blocking api.agentlab.cresclab.com.
  **What to do** Open this page from another network, such as a phone hotspot. If it works there, ask your IT team to allow `api.agentlab.cresclab.com` on port 443. If it is unreachable from every network, it is most likely on our side: write to [info@cresclab.com](mailto:info@cresclab.com) with the time.

What this page checks

## The Gateway itself, nothing more

- This page only asks whether our hosted Gateway is ready. It does not tell you whether a model provider has capacity, or whether your workspace has access or room in its limits.
- The answer is what this device on this network sees. It is not stored, and there is no history.
- To check from a server: `curl https://api.agentlab.cresclab.com/v1/gateway/readiness`. An answer of `{"status":"ready"}` means it is operational. For a self-hosted Gateway, ask your own server's `/v1/gateway/readiness`.
