Is your AI agent up, or up but wrong?

An AI endpoint can return HTTP 200 and still give a wrong answer. This free checker sends your prompt to any agent or LLM endpoint and uses Claude to judge whether the response actually meets your expectation. No signup required.

The free checker runs a few times per hour. To watch an agent continuously, get alerts on failures, and track latency and cost, create a free Senal Ops account.
