List all extractors available to namespace

List all feature extractors available for use in this namespace.

This endpoint returns a unified view combining:

• Builtin extractors: Core extractors shipped with Mixpeek (text_extractor, image_extractor, etc.)
• Custom plugins: User-uploaded plugins at org or namespace level (Enterprise)

Each extractor includes:

• input_schema: JSON schema for input data validation
• output_schema: JSON schema for output document structure
• parameter_schema: JSON schema for configurable parameters
• required_vector_indexes: Vector indexes produced by this extractor
• feature_uri: URI to reference this extractor in collections

Use Cases:

• Discover available extractors when creating collections
• Get schema information for SDK code generation
• Check which custom plugins are deployed

Filtering:

• source=builtin: Only builtin extractors
• source=custom: Only custom plugins
• source=all (default): All extractors

Mixpeek API key, sent as Authorization: Bearer mxp_sk_.... Create one in Studio under Settings → API Keys, or with an admin key via POST /v1/organizations/users/{user_email}/api-keys. A missing header returns 403; an invalid or revoked key returns 401.

X-Namespace · string · header · required
