The AI router with built-in observability & automated evals. Route every model through one API, then trace, monitor, and red-team every agent run. Point the SDK you already use at one endpoint to reach 1,000+ models, with automatic fallbacks, response caching, and spend limits built in. Send every request to one endpoint, reach 1,000+ models across every major provider, and switch between them by changing a single word. List the models to fall back to, and Respan moves to the next the moment one errors or rate-limits, so an outage never takes you down. Cache a request and its response, then serve the same call again instantly, cutting the cost and latency of every repeat to nothing.
