ArcGIS REST API Reference

The Raleigh Open Data portal is built on ArcGIS Hub and exposes datasets through standard ArcGIS REST API endpoints.

Live Catalog Discovery

The CLI discovers the current catalog from the ArcGIS Hub Search API:

https://data.raleighnc.gov/api/search/v1/collections/{collection}/items?startindex={startindex}&limit={limit}

Collections: dataset, document, appAndMap.

The CLI paginates through each collection, normalizes records, caches the result, and validates canonical URLs on demand.

Layer Info

Get metadata about a specific layer:

{serviceUrl}?f=json

For FeatureServer:

https://services.arcgis.com/v400IkDOw1ad7Yad/arcgis/rest/services/DogParkLocations_Existing_PUBLIC/FeatureServer/0?f=json

For MapServer:

https://maps.wake.gov/arcgis/rest/services/Inspections/RestaurantInspectionsOpenData/MapServer/1?f=json

Query Records

{serviceUrl}/query?where={where}&outFields={fields}&returnGeometry={true|false}&f={format}&resultRecordCount={limit}&resultOffset={offset}&orderByFields={fields}&outSR=4326

Parameter	Description	Example
`where`	SQL WHERE clause	`1=1`, `SCORE<70`
`outFields`	Comma-separated field names	`*`, `SITE,ADDRESS`
`returnGeometry`	Include spatial data	`true`, `false`
`f`	Output format	`geojson`, `json`, `html`
`resultRecordCount`	Max records per request	`10`, `1000`
`resultOffset`	Pagination offset	`0`, `1000`
`orderByFields`	Sort fields	`SCORE DESC`
`outSR`	Output spatial reference	`4326`

Export Formats

Format	Parameter	Use Case
GeoJSON	`f=geojson`	Spatial data in standard format
JSON	`f=json`	Tabular/attribute data
HTML	`f=html`	Human-readable table

Notes

All endpoints are public; no API key is required.
Dates are returned as Unix timestamps in milliseconds.
returnGeometry=false is faster for tabular queries.
MapServer layers with type: "Table" have no geometry.
String values in WHERE must be single-quoted.
