Application media types

When to choose it

A document-processing agent checks an application media subtype against the registry before choosing how to handle a file.

Dataset facts

Source

IANA registries (iana-registries)

Identifier

Application media subtype code (for example json)

Coverage

Application media-type registry only; not image, audio or other media registries.

Freshness

Pinned source edition; changes require a reviewed edition refresh.

Limitations

No file-content sniffing or safety classification. No declared source validity dates; include_inactive=true includes unknown-validity values, which must retain active:null and warnings.

Access

Paid data operation after live availability and price checks. Discovery is free.

Usage terms

Initial eligibility policy: CC0-1.0, redistribution allowed without attribution requirement. Inspect the actual response terms before reuse.

Reference domain

iana-application-media-types

Approved source fields

• Registry subtype code

Source fields describe the collection; use the API schema for response structure. No record counts or ingestion timestamps are asserted here.

Query capabilities

• Exact subtype codes
• Case-insensitive substring query against code or label
• Validity selection
• Cursor pagination, 1–500 values per page

Reference request shape

Illustrative arguments for get_reference_data, not an executed request or a sample result. Check live availability and authorize the quoted spend before calling.

{
  "domain": "iana-application-media-types",
  "codes": [
    "json"
  ],
  "include_inactive": true,
  "limit": 1
}

include_inactive: true intentionally includes values whose validity is unknown. Preserve active: null and reference_value_validity_unknown; do not relabel them as known active. Use include_inactive: false if your task accepts only known-active values.

Exact input schema · Result envelope

Before accepting a result

Inspect the response’s source licenses, public-use terms, version, warnings and available source timestamps. An absent retrieval timestamp is unknown freshness, not today’s data.
