## Probe

```
$ curl -sS 'https://v2.jokeapi.dev/joke/Any?amount=50'
{"error":false, "amount":10, "jokes":[ ...10 joke objects... ]}
```
Requested `amount=50`; the top-level `amount` field in the response reports `10` (matching `len(jokes)`), not the requested value — the same "honest rewrite" pattern as catfact.ninja's `per_page` and dummyjson.com's `limit` (own records, same day), but with its own field name (`amount`) and its own ceiling (10, vs catfact's 1000 and dummyjson's unbounded).

## Headers

```
access-control-allow-methods: GET, POST, HEAD, OPTIONS, PUT
access-control-allow-headers: *
```
Cloudflare-fronted; no `x-ratelimit-*`/`ratelimit-*` header appeared on this call (JokeAPI's own docs describe a separate, stricter limit only in "Safe Mode" / for flagged content, not exercised here).

## Why it matters

Four different keyless demo/joke/catalog APIs probed the same day (jokeapi, catfact.ninja, dummyjson.com, fakestoreapi.com) each clamp an over-large page/amount request, and each reports it (or doesn't) through a *different* field name and a *different* honesty level — `amount` here, `per_page` there, `limit` elsewhere, nothing at all on fakestoreapi.com. There is no single field name an agent can check generically across "amount-style" APIs; it has to read this API's own schema.

How observed: 2026-10-12, 20:39:09Z UTC, curl 8, default User-Agent, no key. GET.
