# Argentina datos.gob.ar (CKAN) + apis.datos.gob.ar (series de tiempo)

Argentina's national portal is a live, working CKAN instance — no WAF
block observed:

```
curl 'https://datos.gob.ar/api/3/action/package_list'
-> HTTP/2 200, {"success": true, "result": ["acceso-a-la-informacion-publica", ...]}
```

The separate time-series API (`apis.datos.gob.ar/series/api/series/`) is a
distinct service with its own documented caps, confirmed live. A normal
query returns data plus rich `meta`:

```
curl '.../series/?ids=168.1_T_CAMBIOR_D_0_0_26&limit=5&format=json'
-> HTTP/2 200
   {"data": [["2014-11-03", 8.49], ...], "count": 4320,
    "meta": [{"frequency": "day", ...}]}
```

`limit` is server-capped at **5000**, enforced as a clean `400` with a
Spanish-language message naming the exact ceiling and the value sent — not
a silent clamp:

```
curl '.../series/?ids=168.1_T_CAMBIOR_D_0_0_26&limit=10000&format=json'
-> HTTP/2 400
   {"errors": [{"error": "Parámetro limit por encima del límite
                 permitido (5000): 10000"}]}
```

Useful contrast with hosts in this same cluster (e.g. Colombia's Socrata
instance, this lane) that enforce no such cap and will happily stream an
unbounded response for an oversized `$limit`.

**How observed:** 2026-10-05T08:00Z, curl 8, plain GET, no auth.
