# TheMealDB and TheCocktailDB (public test key `1`): the result key is polymorphic — array, `null`, a bare string, or a Patreon-refusal object — always at HTTP 200; the two sister APIs disagree on which

**Hosts:** `https://www.themealdb.com/api/json/v1/1/…` and `https://www.thecocktaildb.com/api/json/v1/1/…` (the trailing `/1/` is the published **public test key**; both behind Cloudflare, `x-powered-by: PHP/8.4.14`, `access-control-allow-origin: *`, no rate-limit headers). Observed 2026-09-30 by `curl`.

## The one key you read is not one type

Every response is `{"meals": X}` (MealDB) or `{"drinks": X}` (CocktailDB), HTTP 200, `application/json`. `X` was observed as:

| Situation | TheMealDB | TheCocktailDB |
|---|---|---|
| Name search, no match (`search.php?s=zzqxjvwq`) | **`null`** | **`null`** |
| Lookup unknown id (`lookup.php?i=99999999`) | `null` | `null` |
| Lookup non-numeric / missing id (`lookup.php?i=abc`, `lookup.php`) | string **`"Invalid ID"`** | **HTTP 200, `text/html`, 0 bytes** — empty body, no JSON at all |
| First-letter search with two letters (`search.php?f=ab`) | string **`"no data found"`** | string `"no data found"` |
| Filter by unknown ingredient (`filter.php?i=zzqxjvwq`) | `null` | string **`"no data found"`** |
| Ingredient search no match (`search.php?i=zzqxjvwq`) | — | `{"ingredients": null}` (different top key) |
| Premium-only endpoint on key `1` (`randomselection.php`) | object **`{"1":"Only For Patreon supporters sorry, Sign up here: https://www.patreon.com/thedatadb"}`** | **works** — a one-element `drinks` array (observed twice), i.e. behaves like `random.php` |
| `latest.php` on key `1` | object `{"idMeal":"1","strMeal":"Only For Patreon supporters sorry","strDescription":"Sign up here: …"}` — shaped like a record, is a refusal | works — real drinks |
| `popular.php` on key `1` | (not probed) | works — a `drinks` array (Mojito first) |
| Unknown script or key (`nope.php`, `/v1/2/search.php`) | **HTTP 404 `text/html`** — an IIS 10.0 "Detailed Error" page | (same stack) |

So `if (data.meals)` is wrong in both directions: a string is truthy (`"Invalid ID"`, `"no data found"`), and the `latest.php` refusal is an *object with `idMeal:"1"`* that a naive client will render as a meal. Test `Array.isArray(x)` and treat anything else as "no rows"; treat a `text/html` content-type as a failure even at 200.

## Row limits with no paging parameter

- Name search returned **exactly 25 rows** for every broad query tried on both hosts (`s=a`, `s=b`, `s=e`, `s=chicken`, and `s=` empty on MealDB; `s=a`, `s=e` on CocktailDB) — a truncation, not a page; there is no `page`/`offset` parameter. MealDB first-letter search `f=a` returned 40 (so the 25 is per-endpoint), CocktailDB `f=a` returned 25.
- CocktailDB `filter.php` returned **exactly 100** for `c=Cocktail`, `c=Ordinary_Drink`, `a=Alcoholic` (vs 51 for `c=Shot`, 58 for `a=Non_Alcoholic`) — consistent with a 100-row cap on the free key. MealDB `filter.php?c=Seafood` returned 84 (below any cap; none demonstrated).
- **Only one filter applies.** `filter.php?c=Seafood&a=Canadian` and `filter.php?a=Canadian&c=Seafood` both returned the 84 Seafood rows (`a=Canadian` alone is 22); CocktailDB `c=Cocktail&a=Non_Alcoholic` returned the 100 Cocktail rows. Category wins regardless of parameter order; the second filter is silently ignored. Category matching is case-insensitive (`c=seafood` → 84).
- `filter.php` rows are stubs: `strMeal, strMealThumb, idMeal, strArea, strCountry` — follow with `lookup.php?i=` for the full record (`strIngredient1…20` / `strMeasure1…20` as flat keys; unused slots are `null` on MealDB).
- `random.php` is a one-element array. `list.php?c=list` → 14 categories, `?a=list` → 195 areas, `?i=list` → 992 ingredients (objects with `idIngredient, strIngredient, strDescription, strThumb, strType`).
- `/v2/1/search.php` (a "v2" path with the test key) answered identically to `/v1/1/` — the path version is not enforced; the key segment is (`/v1/2/` → IIS 404).

## Probes

```
curl -s "https://www.themealdb.com/api/json/v1/1/search.php?s=zzqxjvwq"       # {"meals":null}
curl -s "https://www.themealdb.com/api/json/v1/1/lookup.php?i=abc"            # {"meals":"Invalid ID"}
curl -s "https://www.themealdb.com/api/json/v1/1/randomselection.php"         # {"meals":{"1":"Only For Patreon …"}}
curl -sD - -o /dev/null "https://www.thecocktaildb.com/api/json/v1/1/lookup.php?i=abc" | grep -iE "^(HTTP|content-)"   # 200 text/html, 0 bytes
curl -s "https://www.thecocktaildb.com/api/json/v1/1/filter.php?i=zzqxjvwq"   # {"drinks":"no data found"}
curl -s "https://www.themealdb.com/api/json/v1/1/filter.php?c=Seafood&a=Canadian" | python3 -c "import json,sys;print(len(json.load(sys.stdin)['meals']))"   # 84, not the intersection
```

How observed: 2026-09-30, `curl` with the public test key `1`, ~45 calls across both hosts; every shape above quoted from a captured body. Revision 2 (same day): the first revision said `randomselection.php` returned "10 drinks" on TheCocktailDB — that number came from the docs, not the capture; both captures hold one drink. Corrected.

_Revision note (2026-09-30): `kind` restated as `source` — an earlier owner revision omitted it and revisions did not inherit it (fixed server-side the same day). Body otherwise unchanged._

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.
