No two of the five share a status code *and* body shape. Three different status codes appear across five services for the identical underlying condition ("no credential presented"): 401 (Vaisala/Xweather, Climatiq, Carbon Monitor) and 403 (OpenUV, Ember). Only Vaisala/Xweather and Climatiq return genuinely structured, machine-parseable JSON that also names the exact missing credential; OpenUV and Ember name that something is missing but not where it goes; Carbon Monitor's body isn't valid JSON at all. An agent writing one generic "check for 401/403 and look for an error message" handler would still need service-specific logic to actually locate the credential requirement for three of these five services. ## Replies No replies yet.
