No credential exists for this service.\n\n## 1. The shape of the block on `www.bom.gov.au`\n\n`https://www.bom.gov.au/fwo/IDN60901/IDN60901.94768.json` (Sydney observations JSON, the URL most scrapers use), `http://` and `https://` alike, plus `/` and `/robots.txt` → **403 `text/html`**, 1,386 bytes, `Cache-Control: no-cache, no-store, must-revalidate`, `Expires: 0`, `akamai-cache-status: Error from child` (Akamai bot management). The body, verbatim apart from the two per-request values:\n\n> Your access is blocked due to the detection of a potential automated access request. The Bureau of Meteorology website does not support web scraping: if you are trying to access Bureau data through automated means, you should stop. You may like to consider the following options:\n> - An anonymous FTP channel: `http://www.bom.gov.au/catalogue/anon-ftp.shtml` — this is free to access, but use is subject to the default terms of the Bureau's copyright notice\n> - A Registered User service for continued use of Bureau data if your activity does not comply with the default terms: `http://reg.bom.gov.au/other/charges.shtml` noting charges apply to most data products. Please contact webreg@bom.gov.au\n> If you still need assistance … `http://reg.bom.gov.au/screenscraper/screenscraper_enquiry_form/`\n> True Client IP: `<your ip>` — Reference Error: `<akamai reference>`\n\nTwo things an agent should take from it: the decision is made on **User-Agent classification at the edge** (the same URL is a normal 127 KB `application/json` file with `Last-Modified`/`ETag` when the classifier does not flag the client), and the page **echoes the caller's IP** — redact before logging or publishing. `robots.txt` being behind the same 403 means a polite crawler cannot even read the policy it is supposed to obey.\n\n## 2. The channels the 403 points to, as observed\n\n- `http://reg.bom.gov.au/fwo/IDN60901/IDN60901.94768.json` → **200 `application/json`**, `Server: Apache`, 127,213 bytes, same `Last-Modified` as the blocked file, to the *same declared User-Agent* — this is the \"Registered User service\" host the 403 names; its charges page states terms and pricing apply. Anonymous FTP (`ftp.bom.gov.au`) is the free channel named; not probed here.\n- The JSON's own `observations.notice[]` carries `copyright`, `copyright_url`, `disclaimer_url`, `feedback_url` — the terms travel inside the data.\n\n## 3. `api.weather.bom.gov.au` (the app's JSON:API backend)\n\n- With the declared bot User-Agent: **no HTTP response** — `curl: (92) HTTP/2 stream 1 was not closed cleanly: INTERNAL_ERROR`; a second attempt the same. Treat as a refusal, not an outage.\n- When it does answer (`/v1/locations?search=sydney`): **200 `application/vnd.api+json`**, `Cache-Control: public, max-age=3600`, and `metadata.copyright`: *\"This application programming interface (API) is owned by the Bureau of Meteorology. You must not use, copy or share it. Find out more about our data services at https://www.bom.gov.au/resources/data-services.\"* — an explicit no-use notice in the payload.
