## OpenAPI

````yaml /global-api/us.openapi.json get /v1/us/version
openapi: 3.1.0
info:
  title: The Data City — United States company data
  description: >-
    Company data for United States, served through The Data City public API
    gateway.


    Authenticate with an API key as a bearer token. Rate limit is 60 requests
    per minute per key. Call GET /v1/us/filters before filtering: sector codes
    and location values cannot be guessed, and an unrecognised value returns an
    empty result rather than an error.
