# The Muse public jobs API (www.themuse.com/api/public/jobs): CloudFront blocks the `curl/*` and `python-requests/*` User-Agents on `/jobs` only (`/companies` passes with the same UA; an empty UA passes everywhere); `page` is mandatory and 0-based; `page=100` and above is 400 "Value `page` is too high" while every body advertises `page_count: 20638`; `category` is case-sensitive and a bogus one is a 200 with `total: 0`

**What it is.** A keyless job-listing API: `GET https://www.themuse.com/api/public/jobs?page=N` (20 rows per page, filters `category`, `level`, `location`, `company`, `descending`), plus `/api/public/companies` and `/api/public/jobs/{id}`. Backed by `TornadoServer/4.5.3` behind CloudFront.

**1. The edge rule is per path, per User-Agent.** Observed 2026-09-30, curl 8.17.0:

```
curl -s -D - 'https://www.themuse.com/api/public/jobs?page=1'
```

→ HTTP **403**, `text/html`, 919 bytes, `Server: CloudFront`, `x-cache: Error from cloudfront`: "ERROR: The request could not be satisfied … Request blocked … Generated by cloudfront (CloudFront) Request ID: …". Same for `page=0`, no `page`, `page=99999`, `page=abc`, `&category=…`, `&descending=true`, and `/api/public/jobs/1`.

| User-Agent | `/api/public/jobs?page=1` | `/api/public/companies?page=1` |
|---|---|---|
| curl default (`curl/8.17.0`) | **403** CloudFront HTML | **200** JSON |
| `python-requests/2.32.3` | **403** CloudFront HTML | *(not probed)* |
| `-A ''` (header suppressed) | 200 JSON | *(not probed)* |
| `nh-batch15-probe/1.0` | 200 JSON | 200 JSON |
| `Mozilla/5.0 (…) Chrome/128` | 200 JSON | *(not probed)* |

`Accept: application/json` makes no difference. So a curl user sees `/companies` work and `/jobs` "blocked" and reasonably concludes the jobs endpoint is down — it is a User-Agent rule scoped to that path. Meanwhile `/api/public/bogus` with the curl UA is a clean **404 JSON** `{"code": 404, "error": "Not found"}` — the origin is reachable; only `/jobs` is filtered.

**2. `page` is mandatory, 0-based, and capped at 99 regardless of `page_count`.** With `-A 'nh-batch15-probe/1.0'`:

| Request | Result |
|---|---|
| `?page=0` | 200, `{"page": 0, "page_count": 20638, "items_per_page": 20, "took": 12, "timed_out": false, "total": 412742, "results": [ …20 rows… ], "aggregations": {}}` |
| `?page=1` | 200, 20 rows, none shared with page 0 or page 2 — **page 0 is a real page, so pages are 0-based** |
| *(no `page`)* | **400** `{"code": 400, "error": "Not a valid argument for 'page'"}` |
| `?page=abc` | 400, same "Not a valid argument" |
| `?page=-1` | 400 `{"code": 400, "error": "Value `page` is too low"}` |
| `?page=99` | **200**, 20 rows |
| `?page=100` | **400 `{"code": 400, "error": "Value `page` is too high"}`** |
| `?page=101`, `199`, `200`, `250`, `300`, `400`, `499`, `500`, `20637`, `20638`, `99999` | 400 "too high" — every one |

So the reachable window is pages 0–99 = **2,000 rows of an advertised 412,742**, and the body's `page_count: 20638` is the count the server *would* have, not the count you can fetch. Narrow with filters instead: `category=Software%20Engineering` → `total: 98412, page_count: 4921` (still only pages 0–99 reachable); `location=Flexible%20%2F%20Remote` → `total: 6106`.

**3. Filters: one is strict, one is silent.** `category=Software%20Engineering` → 98,412 hits; **`category=software%20engineering` → 200, `total: 0`** (case-sensitive); `category=Bogus` → 200, `total: 0`, `page_count: 0` — and `page=5&category=Bogus` is also 200/`total: 0`, not "too high" (the ceiling check does not run against an empty result). **`level=Bogus` is silently ignored** — 200 with the full 412,742. `descending=true` reorders (first row's `publication_date` moved from 2025-01-17 to 2025-11-23) but does not otherwise change counts. Default order is not date order.

**4. Item endpoint and rate limit.** `/api/public/jobs/1` and `/jobs/abc` → 404 `{"code": 404, "error": "Not found"}`. `?api_key=<placeholder>` → **403** `{"code": 403, "error": "Invalid API key"}` — a wrong key is worse than no key. Keyless 200s carry `x-ratelimit-limit: 500`, `x-ratelimit-remaining: 498…`, `x-ratelimit-reset: 3523` (seconds; a rolling hour); the 400s and the CloudFront 403 carry **no** rate headers. `/companies` showed `remaining: 499` while `/jobs` was at 497 in the same minute — recorded as observed, not interpreted. `/api/v2/jobs?page=1` → 403 JSON `{"code": 403, "error": "Request includes unexpected headers."}`.

**Practical rule.** Set a non-`curl`, non-`python-requests` User-Agent (or none). Start at `page=0`. Do not trust `page_count`; you get 100 pages. Spell `category` exactly as the API returns it (`results[].categories[].name`).

How observed: 2026-09-30, direct HTTPS with curl 8.17.0, 51 GET requests to `www.themuse.com` (10 with the default UA, the rest with `nh-batch15-probe/1.0`, `Mozilla/5.0 …`, `python-requests/2.32.3` or no UA), page ceiling bisected 99/100 then confirmed at 13 higher values. Method: GET only.
