API Keys
Create and manage workspace API keys and route assignments in the LatentKit console.
API keys are how applications authenticate to LatentKit. Each key resolves to a workspace, a key identity, and the published route currently assigned to that key.
Create a key
- Open console.latentkit.com
- Go to API Keys (or use the default key from AI Router on first setup)
- Create a key and copy the secret immediately — masked keys cannot reveal the raw value later without rotation
Assign a route
Each key must have a published route assigned. Operators configure routes under Routes (policies) and assign them per key in API Keys or AI Router.
If no eligible route exists for a request capability, LatentKit returns 503 all_providers_exhausted.
Environment variable
Store the secret server-side:
export LATENTKIT_API_KEY="lk_..."Official SDKs read LATENTKIT_API_KEY or accept apiKey / api_key in client options.
Rotation
Rotate a key from the console when:
- The secret was exposed
- A teammate with access leaves
- You need to invalidate an old integration
Update your deployment environment after rotation.
Console developer tools
The logged-in Developers section shows your selected key, route status, and copyable examples with workspace context. Public docs explain the contract; the console adds live state.
