OS NGD API - Tiles

OGC API - Tiles conformant vector tile service over the OS National Geographic Database, including tile matrix sets and styles. The OpenAPI 3.0.1 description is served live and anonymously at /api.

Documentation Provider Profile APIs.io OpenAPI GitHub

OS NGD API - Tiles is one of 12 APIs that Ordnance Survey publishes on the APIs.io network, described by a machine-readable OpenAPI specification.

Tagged areas include Tiles, OGC API, Vector Tiles, and Mapping. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and an API reference.

This API exposes 13 operations across 13 paths, organized into 6 resource areas, and defines 32 schemas. It is described by OpenAPI 3.0.1, at version v1.8.

Requests are made against a single base URL, https://api.os.uk/maps/vector/ngd/ota/v1.

Where this information came from

This is an independent, third-party profile of OS NGD API - Tiles, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
