About
A gateway, not a model.
Korlogic puts one OpenAI- and Anthropic-compatible endpoint in front of 14 frontier models. Your code keeps its SDK and changes one base URL.
What it actually is
- One endpoint
- Two base URLs, one for each billing mode. Both speak the OpenAI Chat Completions shape and the Anthropic Messages shape, including streaming.https://api.korlogic.com/v1https://api.korlogic.com/token/v1
- One key
- The same key authenticates your API calls and signs you in here. There is no separate account, no username and no password to lose.
- No signup
- Keys are issued by the operator, not minted by a form. Nothing on this site creates one, so there is no unverified-account surface to abuse.
How it bills
- Prepaid
- A key holds either a USD credit balance or a fixed token budget — never a running tab. When it is empty, requests stop; nothing is invoiced afterwards.
- Per request
- Every call is metered on its own reported token usage and charged at the model’s rate. The usage checker shows each one.
- Failures are free
- A request that errors upstream, or that comes back without usable usage figures, is recorded at zero cost. You are never charged for a request we could not bill for.
What the operator controls
- Model allowlist
- A key can be restricted to a named subset of the catalog. An empty list means the whole catalog; anything else is refused before the request leaves us.
- Rate limit
- Each key carries its own requests-per-minute ceiling.
- Expiry and status
- A key can be given an expiry date and can be suspended or resumed at any time. Both take effect on the next request, not at the next sign-in.
The catalog
14 models are reachable through the same endpoint. Which of them a given key may call depends on its allowlist; rates are per model and visible to your operator.
