One API, 500+ models

Send a request to api.hanzo.ai and name a model. Change the name and the same request reaches a different one — our own Zen family, or a frontier model from someone else. One key, one bill, one place to see what every call cost and how long it took. Set a spend ceiling and a rate limit per key, so a runaway loop stops at a number you chose instead of at the end of the month.
