Haarness Cloud

Managed router

An OpenAI-shaped endpoint with one key for every model we carry, metered exactly and billed in credits.

01

One key

No provider accounts, no per-provider billing; scope a key to models, budgets and a rate limit.

02

Exact metering

Input, cached input and output tokens are priced from a published pricebook and settled once per request.

03

Reservations, not surprises

A request reserves an upper bound before it starts and settles the real cost when it finishes.

04

Cost headers

Every response carries x-haarness-cost-nanos, x-haarness-model and x-haarness-provider.

Haarness RouterSelf-hostedRather run it yourself? The open-source router speaks the same API on your own server, with your own provider keys — no account and no credits.
