# Florida GIO Hub (geodata.floridagio.gov): v3 catalog is strict JSON:API, layers are plain Esri

Florida's state GIS clearinghouse runs an ArcGIS Hub `/api/v3/datasets`
catalog (JSON:API-shaped) in front of ordinary Esri FeatureServer layers —
two different parameter grammars one hop apart.

## Probe 1 — the v3 catalog rejects the intuitive `size` param

```
curl "https://geodata.floridagio.gov/api/v3/datasets?q=county&size=3"
```
Response: HTTP **400**,
```json
{"errors":[{"title":"Invalid Parameter","detail":"'size' is an invalid parameter","status":400}],"meta":{}}
```
A plain `size` (as several non-JSON:API catalogs in this cluster accept) is
flatly rejected — bracketed JSON:API paging is required:

```
curl --get "https://geodata.floridagio.gov/api/v3/datasets" \
  --data-urlencode 'q=Florida parcels' --data-urlencode 'page[size]=5'
```
→ HTTP 200, `data` array of 5 dataset records, each
`attributes.advancedQueryCapabilities` echoing the full Esri REST feature
surface (supportsSqlExpression, supportsStatistics, etc.) and an
`attributes.url` pointing at the live FeatureServer/MapServer layer.

## Probe 2 — the underlying FeatureServer layer's own hard cap

One `v3` hit returns `url: "https://services3.arcgis.com/DvTqoyLKkslnGFR5/arcgis/rest/services/Madison_County_Florida/FeatureServer/0"`
("Madison County Florida" parcels, true row count 16,247 confirmed via
`returnCountOnly=true`).

```
curl "<that FeatureServer URL>?f=json" # layer metadata
```
→ `"maxRecordCount": 1000`.

```
curl "<that FeatureServer URL>/query?where=1=1&outFields=OBJECTID&resultRecordCount=100000&f=json"
```
→ HTTP 200, `features` array length **1000**, `"exceededTransferLimit":
true` — the requested 100,000 is silently clamped to the layer's own
declared 1,000 ceiling, and this time (unlike the HUD FeatureServer already
in this corpus, where `exceededTransferLimit` lies) the flag is set
correctly and matches the real 16,247-row total.

## Why it matters

The catalog layer (`/api/v3/datasets`) and the data layer
(`FeatureServer/query`) are two unrelated APIs with two unrelated paging
grammars, chained by a single `url` field — an agent has to detect which
layer it is talking to (JSON:API vs raw Esri REST) before guessing a page
parameter name, and even after finding the real data endpoint must still
respect the per-layer `maxRecordCount` rather than the size it asked for.

How observed: 2026-10-05T09:42:56Z-09:43:20Z, plain `curl` against
geodata.floridagio.gov and services3.arcgis.com, no credential sent or
required for any probe.
