    The OpenAPI ASCE publishes carries no operationIds, no info.contact, no
    info.license, no tag descriptions and no response content schemas. This
    overlay records the additions API Evangelist would apply so agents and
    generators have stable handles; it never mutates the harvested original.
    Every value here is traceable to a provider-published source — the API
    documentation page, the JSON field documentation PDF, or a recorded probe.

        The ASCE Hazard Tool API provides a simple interface to query locations
        in the United States for environmental hazard data by geographic
        location. It returns ASCE 7-22, 7-16 and 7-10 wind, ice, rain, flood,
        seismic, snow, tornado and tsunami data, plus ASCE 41-17 and 41-23
        seismic data, for the contiguous United States, Alaska, Hawaii, Puerto
        Rico, Guam, American Samoa and the U.S. Virgin Islands. All requests
        authenticate with an API key passed as the `token` query parameter.

    description: Drop the non-routable development server from the consumable copy.
    remove: false
    update:
      - url: https://api-hazard.asce.org/v1
        description: Production. The second entry in the published spec, http://localhost:3000/v1, is a development host and is not callable by consumers.
  - target: $.paths['/flood'].get
    update:
      operationId: getFlood
      description: >-
        Returns the FEMA National Flood Hazard Layer flood zone classification,
        static base flood elevation (-9999 when not applicable) and vertical
        datum for the coordinate.
  - target: $.paths['/ice'].get
    update:
      operationId: getIce
      description: >-
        Returns ASCE 7 equivalent radial ice thickness due to freezing rain,
        concurrent temperature and concurrent 3-second gust speed. Response shape
        differs between the 7-10/7-16 editions and 7-22.
  - target: $.paths['/rain'].get
    update:
      operationId: getRain
      description: >-
        Returns the NOAA Atlas 14 precipitation frequency table for the
        coordinate: 19 duration rows by 9 average recurrence intervals, in
        inches/hour.
  - target: $.paths['/seismic'].get
    update:
      operationId: getSeismic
      description: >-
        Returns USGS Seismic Design Web Services values for the coordinate under
        the selected ASCE 7 or ASCE 41 edition. Valid siteClass values differ by
        edition; an out-of-edition value returns an invalid input error.
  - target: $.paths['/snow'].get
    update:
      operationId: getSnow
      description: >-
        Returns ASCE 7 ground snow load. A value of "Case Study" (or an Alaska
        Notes field reading "Case Study" with a load of 0) means a site-specific
        study is required and the number must not be read as a load.
  - target: $.paths['/tornado'].get
    update:
      operationId: getTornado
      description: >-
        Returns ASCE 7-22 tornado wind speeds by effective plan area and mean
        recurrence interval. Tornado hazard data applies only to Risk Category
        III and IV; for I and II the response carries isRiskLevelApplicable and
        no values.
  - target: $.paths['/tsunami'].get
    update:
      operationId: getTsunami
      description: >-
        Reports whether the coordinate falls inside the mapped tsunami design
        zone. Returns GIS data about the TDZ shape when inside it, and an empty
        features object when outside it or when standardsVersion is 7-10.
  - target: $.paths['/wind'].get
    update:
      operationId: getWind
      description: >-
        Returns ASCE 7 3-second gust design wind speeds at 33 ft above ground for
        Exposure C across multiple mean recurrence intervals, plus
        hurricane-prone and special wind region flags. Wind always returns speeds
        for all Risk Categories, but a riskLevel must still be supplied.
  - target: $.paths.*.get.responses['401']
    description: Record the observed 401 envelope, which the published spec omits.
    update:
      description: >-
        Token required. Observed 2026-09-07 on an anonymous call to
        https://api-hazard.asce.org/v1/wind — {"code":401,"message":"Token required"}.
        Note the documentation page describes a missing or invalid key as code 500.
  - target: $.components.securitySchemes.ApiKeyAuth
    update:
      description: >-
        API key issued per company through the ASCE Hazard Tool Account Manager
        and passed as the `token` query parameter. Because the credential travels
        in the query string it is echoed back in requestInfo.url on every
        successful response and will appear in logs.
  - target: $.tags
    description: Declare the eight hazard tags the operations already use.
