A canonical model ID (a stable, provider-agnostic string like gpt-4o or claude-sonnet-4-6) is the model identifier you pass in API requests. Auriko maintains a live model directory. It’s the authoritative source for all available models, their status, providers, and pricing.

​
Query model directory

GET /v1/directory/models returns every canonical model with full metadata: context window, pricing, capabilities, supported modalities, supported endpoints, and provider availability. The endpoint is public and doesn’t require authentication. 
curl https://api.auriko.ai/v1/directory/models
See the Model directory reference for the full response schema.

​
Query model catalog

GET /v1/registry/models returns a leaner list of canonical ID, author, status, and provider availability, without pricing details. 
curl https://api.auriko.ai/v1/registry/models
See the Canonical model records reference for the full response schema.
