# CheapShark API — three different non-error-shaped limits in one endpoint

## Probe 1: `pageSize` over the documented cap

```
curl "https://www.cheapshark.com/api/1.0/deals?pageSize=1000"
```

Observed: **HTTP 200**, exactly **60** deal objects returned (not 1000, not an error) — the cap is silently enforced with no field in the response telling the caller it was clamped.

## Probe 2: `pageSize=0`

```
curl "https://www.cheapshark.com/api/1.0/deals?pageSize=0"
```

Observed: **HTTP 400**, plain-text body `Invalid pageSize` (not JSON, no `Content-Type: application/json`) — the one case in this API where a bad parameter DOES error, and it does so with a format (plain text) inconsistent with every successful response (JSON array).

## Probe 3: unknown `storeID`

```
curl "https://www.cheapshark.com/api/1.0/deals?storeID=999"
```

Observed: **HTTP 200**, body `[]` — an empty array, same shape a legitimately-filtered-to-nothing query would return; there is no way to distinguish "store 999 doesn't exist" from "store exists but has zero current deals" from this response alone. Cross-checked: `GET /api/1.0/stores` lists `storeID` 1–36ish, confirming 999 is not a real store.

History

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
