  Full read of the nisos.com Yoast page sitemap (144 URLs) for a documented limit, plus
  anonymous response-header inspection of both Ascend API hosts, 2026-08-26.

    status: 403
    note: >-
      AWS API Gateway rejects anonymously (x-amzn-errortype ForbiddenException). Response
      carries no X-RateLimit-*, no RateLimit-* and no Retry-After header, so no runtime
      rate-limit signal is observable without credentials.

    status: 403
    note: nginx 403 with no rate-limit headers
note: >-
  Nisos documents no rate limits anywhere on its public surface — there is no developer
  portal, no API reference and no published contract in which limits could be stated. The
  live API hosts emit no rate-limit headers to an anonymous caller. An honest zero.
