      summary: List known providers
      description: Returns every (vendor, model) pair the router knows about per pipeline layer, plus one vendor-wildcard row per vendor. The `id` field on each entry is the verbatim string callers put into `allowedProviders` on session create, transcribe, synthesize, complete, or `stackPreferences` on an agent. Use this to populate UI pickers or validate user-supplied allowlists.

    KnownProviders:

    ProviderModelEntry:
      type: object
      description: A single allowlist-eligible entry returned by `/v1/providers/known`. The `id` is the verbatim string callers put into `allowedProviders` — either a vendor wildcard (`"deepgram"`) or a specific (vendor, model) pair (`"deepgram:nova-3"`).
      required:
      - id
      - vendor
      - vendorName
      - model
      - benchmarked
      properties:
        id:
          type: string
          description: Verbatim string for `allowedProviders` entries. `"<vendor>"` for vendor-wildcard rows, `"<vendor>:<model>"` for model-specific rows.
          examples:
          - deepgram
          - deepgram:nova-3
        vendor:
          type: string
          description: Lowercase vendor id.
          examples:

          description: Human-readable vendor name.
          examples:
          - Deepgram

          type:
          - string
          - 'null'
          description: Model id within the vendor, or `null` for the vendor-wildcard row.
          examples:
          - nova-3
        benchmarked:
          type: boolean
          description: Whether the router has benchmark data for this entry. `false` entries are visible but cannot win selection — including them in `allowedProviders` without a benchmarked fallback will fail to route.
