  official OS API Wrappers page names JavaScript/npm, Python/PyPI and R/CRAN),
  cross-checked against the npm, PyPI and CRAN registries and the
  github.com/OrdnanceSurvey organisation.
description: >-
  Ordnance Survey publishes first-party API wrappers in three languages and
  ships them from its own GitHub organisation. The osdatahub family is the
  current supported line; OS-PAW is the superseded Python wrapper it replaced.
  osbng is a separate first-party library for the OS British National Grid
  indexing system rather than an API client.

      OS Python API Wrapper - the earlier first-party Python client, superseded
      by osdatahub
sdk_summary:
  official_client_libraries: 3
  languages: [python, javascript, r]
  note: >-
    Counted as the three osdatahub wrappers OS itself lists on the OS API
    Wrappers page. No first-party Java, .NET, Go, Ruby or PHP client is
    published.
gaps:
  - No first-party CLI is published (see cli/ - none found).
  - >-
    No first-party SDK covers OS Downloads API, OS Net API, OS Features API
    (WFS), OS Maps API or OS Vector Tile API - the wrappers target the search
    and NGD Features surfaces only.
