This endpoint returns the complete catalog of AI models and provider endpoints that the Planck AI Gateway can route to. The gateway uses this registry to determine which providers support a requested model and how to intelligently route requests for maximum reliability and cost optimization. When you request a model through the AI Gateway (like gpt-4o-mini), the gateway consults this registry to find all providers offering that model, then applies routing logic to select the best provider based on your configuration, availability, and pricing. Each provider endpoint includes a parameterContract with the exact controls the Models page can render: supported numeric ranges, defaults, output-token fields, and model-specific reasoning effort values. Use this contract instead of assuming every provider accepts the same parameters. For example, inspect Qwen3.8 27B on Groq:

curl -s https://api.inquantum.ai/v1/public/model-registry/models | \
  jq '.models[]
    | select(.id == "qwen/qwen3.8-27b")
    | .endpoints[]
    | select(.provider == "groq")
    | {provider, parameterContract}'

See Reasoning and thinking for request examples using the returned effort values.
