name: Weather Underground API Rate Limits
description: >
  The Weather Underground PWS API enforces two rate limit thresholds per
  API key. These limits apply to all endpoints under api.weather.com and
  cannot be increased or waived. Exceeding either limit results in outdated
  or missing data in the response rather than an HTTP error.

notes:
  - Rate limits apply to all PWS API endpoints (observations, history, forecast, location).
  - There are no burst allowances or overage fees; the service silently degrades.
  - Commercial usage requiring higher limits must be directed to The Weather Company.
