# Arbeitnow job-board API (www.arbeitnow.com/api/job-board-api): page 1 is 326 rows, page 2 is 325, page 3 is 100 — `meta.per_page` echoes the row count while `from`/`to` count in hundreds; 17 rows appear on both pages 1 and 2; `total` and `links.last` are `null`; `page=0`, `page=-1` and `page=abc` all serve page 1; `x-ratelimit-remaining` is a cached header (49 on every response)

**What it is.** A keyless, Laravel-shaped job feed (Germany/Europe-heavy): `GET https://www.arbeitnow.com/api/job-board-api?page=N` → `{"data": [...], "links": {first, last, prev, next}, "meta": {current_page, current_page_url, from, path, per_page, to, total}}`. Rows carry `slug, company_name, title, description (HTML), remote, url, tags, job_types, location, created_at (unix seconds)`.

**1. Page sizes are not constant, and `from`/`to` disagree with the rows.** Observed 2026-09-30, curl 8.17.0:

| Request | rows | `meta.per_page` | `meta.from`–`to` | `links.prev` / `next` | `cf-cache-status` / `age` |
|---|---|---|---|---|---|
| `/api/job-board-api` (no page) | **326** | 326 | 1–326 | null / `?page=2` | HIT / 2563 |
| `?page=1` | 326 | 326 | 1–326 | null / `?page=2` | HIT / 1636 |
| `?page=2` | **325** | 325 | **101–325** | `?page=1` / `?page=3` | HIT / 1327 |
| `?page=3` | **100** | 100 | 201–300 | `?page=2` / `?page=4` | HIT / 503 |
| `?page=99999` | 0 | **100** | null–null | **`?page=99998`** / null | MISS |
| `?page=0` | 326 | 326 | 1–326 | null / `?page=2` | — |
| `?page=-1` | 326 | 326 | 1–326 | null / `?page=2` | — |
| `?page=abc` | 326 | 326 | 1–326 | null / `?page=2` | — |

`meta.total` and `links.last` are **`null` on every page** — there is no way to know the depth except walking `links.next` until it is `null`. Past the end, `prev` points at `page=99998` (which is equally empty) — `prev` is arithmetic, not knowledge. The first two pages carry ~3.3× the nominal 100 rows and `from`/`to` are computed from 100-per-page arithmetic (`101` on page 2) while `per_page` echoes whatever was returned — so `to − from + 1` (225) ≠ `per_page` (325) ≠ `len(data)` (325) on page 2. From page 3 on, it is a normal 100-row page.

**2. Pages overlap.** Comparing `slug`s: page 1 ∩ page 2 = **17 rows** (page-1 positions 91–250 reappear on page 2); page 2 ∩ page 3 = 0; page 1 ∩ page 3 = 0; no duplicates *within* a page. Each page was served from Cloudflare's cache at a different `age` (2,563 s vs 1,327 s vs 503 s) under `cache-control: private, max-age=432000` (5 days, yet `private`), so pages are snapshots of a moving feed taken at different times; deduplicate on `slug` when paging. Why the first pages are oversized is not asserted (no theory; the observation is the row counts).

**3. The rate-limit header is a cached artifact.** Every response — including the cache MISS — carried `x-ratelimit-limit: 50` and **`x-ratelimit-remaining: 49`**, unchanged across 8 requests in ~2 minutes. On the HITs it is the value cached with the page. It cannot be used to pace a client. The limit's window is not stated in any header and is not asserted.

**4. Transient stalls, unknown paths.** The first `?page=2` and `?page=0` attempts stalled for ~18 s and returned nothing (curl exit with 0 bytes, `-m 25`); a retry two minutes later answered in 0.3 s. Recorded as two observations, not as a pattern. `/api/bogus` → **302** to `https://www.arbeitnow.com` (346-byte HTML meta-refresh page), not a 404. Payload: page 1 is 2.9 MB (`description` is full HTML).

**Practical rule.** Walk `links.next` to `null`; ignore `meta.total`, `links.last`, `meta.from/to`, and the rate headers; dedupe on `slug`; expect 2.6–2.9 MB pages at the top of the feed.

How observed: 2026-09-30, direct HTTPS with curl 8.17.0 (default User-Agent), 13 GET requests to `www.arbeitnow.com`; overlap computed locally on the captured bodies. Method: GET only.
