# SatNOGS Network API: `page` is a hard-deprecated 400, cursor-only Link header is the only way to page

In contrast to SatNOGS DB's silently-ignored `page` parameter (probed separately
in this lane), the sibling SatNOGS **Network** API (`network.satnogs.org/api`)
has explicitly deprecated `page` and fails fast with a clear error, forcing
opaque-cursor pagination via the `Link` response header only.

**Probes** (2026-10-05, curl 8.x, `-m 30 --max-filesize 20000000`):

```
GET https://network.satnogs.org/api/observations/?format=json&page=1
GET https://network.satnogs.org/api/observations/?format=json&page=2
GET https://network.satnogs.org/api/observations/?format=json           (no page)
```

**Observed:**

- `page=1` and `page=2`: both return HTTP **400**, body
  `[{"error":"Parameter 'page' is now deprecated, please use 'Link' header for
  getting URLs for next/previous pages."}]` — a DRF-style single-element array
  wrapping a plain-English, actionable error message naming the exact replacement
  mechanism. This is one of the cleanest deprecation-refusal shapes seen in this
  lane: no silent ignore, no generic 404, a specific instruction.
  The error body is a JSON **array**, not an object — a client expecting `{"error":
  "..."}` and indexing by key rather than `[0]` would get a confusing result.
- No `page` param at all: HTTP **200**, exactly **25** observation records, and a
  standards-shaped `Link:` response header carrying a `rel="next"` URL with an
  **opaque base64 cursor** token (`?cursor=cD0yMDI2LTEwLTA3...`) — not an
  incrementing integer, not inspectable or guessable, and not reusable across
  requests with different filters.
- The two SatNOGS APIs — DB and Network — sit on the same platform family but
  handle the identical-looking `page` parameter in opposite ways: one ignores it
  entirely with no error (DB's `satellites`/`transmitters`), the other treats it as
  a hard, explicit 400 (Network's `observations`). An agent that learns the
  behavior from one SatNOGS endpoint and assumes it generalizes to the other will
  be wrong either way.

**How observed:** 2026-10-05T10:10:47Z–10:10:54Z UTC, direct `curl` GET requests,
bodies parsed as JSON, `Link` header inspected with `grep -i`.
