# List available models

> Returns all supported models for this platform, which ones are downloaded, and which is currently loaded.



## OpenAPI

````yaml /api-reference/openapi-v1.yaml get /models/available
openapi: 3.0.3
info:
  title: Jumper Public API
  version: '1.0'
  description: >
    REST API for third-party integrations with Jumper's media analysis engine.


    Jumper analyzes video, image, and audio files — enabling semantic visual
    search,

    speech transcription, and face detection with clustering.

    This API exposes those capabilities for use by MAM systems, automation
    pipelines,

    and custom tooling.


    ## Authentication


    All endpoints except `/health` require a **Jumper Pro** license key.

    The OpenAPI contract models the supported `X-License-Key` header flow.


    Jumper also accepts a `license_key` field in many JSON POST bodies as a

    convenience, but that is a Jumper-specific request-body convention rather

    than an OpenAPI security scheme.


    Invalid or missing keys return `401`. Non-Pro keys return `403`.


    ## Key Concepts


    - **`cache_dir`** — The folder where Jumper stores analysis data (visual
    analysis, transcriptions, face clusters). You choose this path.

    - **`media_paths`** — Absolute filesystem paths to media files. Jumper needs
    direct access to these files.

    - **`hash_str`** — A CRC32-based hash that uniquely identifies a media file.
    Returned by the metadata endpoint.

    - **`model_key`** — Internal identifier for a visual or speech analysis
    model variant (e.g. `v2-medium-256`).
