# List model catalog

> Returns the catalog of supported models, optionally filtered by provider. When gateway_id and registry_id are supplied for an AWS Bedrock registry, the list is narrowed to the models those credentials can invoke serverless (on-demand base models and system-defined inference profiles), excluding Bedrock Marketplace, Provisioned Throughput and custom models. Malformed ids and unreachable AWS endpoints are ignored and yield the full catalog.
