What are Tempe City APIs and where to find them

Tempe's official Open Data Portal provides searchable datasets, downloadable files, and RESTful API endpoints for most public datasets. Access endpoint URLs and dataset metadata directly on the portal to construct queries and filters for JSON or CSV output. Tempe Open Data Portal[1]

How to access and use city APIs

  • Locate the dataset page on the Open Data Portal and copy the API endpoint URL from the dataset's API tab.
  • Use standard HTTP methods (GET) to request JSON or CSV; include query parameters for filtering, sorting, and pagination.
  • Check dataset metadata for any stated fees or licensing terms; most city datasets are provided as open data but individual dataset terms may vary.
  • Respect privacy and restricted fields; do not attempt to access confidential or protected records via the API.

Applications & Forms

No separate municipal form is required to view or use public API endpoints; most access is immediate via the Open Data Portal and standard HTTP requests. Specific application or app-token procedures are described on the portal's developer resources or dataset pages and are not specified in the Tempe municipal code pages cited below.[1]

Public datasets may still contain restricted fields that are redacted by the city.

Penalties & Enforcement

Use of Tempe city APIs and data is subject to applicable municipal ordinances, state law, and the portal's terms of use. Where the city publishes rules or sanctions relating to misuse, those provisions are found in the Tempe City Code and related policies. Specific fine amounts and escalation steps for improper access or misuse are not specified on the cited pages and therefore are "not specified on the cited page." Tempe City Code[2]

  • Fines: not specified on the cited page.
  • Escalation: first, repeat, or continuing offences - not specified on the cited page.
  • Non-monetary sanctions: injunctions, court orders, or other remedies may be sought under municipal or state law; specific remedies are not itemized on the cited pages.
  • Enforcer: City Attorney, Municipal Court, and relevant departments (e.g., IT or Records) coordinate enforcement; see municipal contacts in Resources.
  • Inspection and complaints: report suspected misuse via official city contact channels listed below.
  • Appeals and review: appeals of municipal citations proceed through the City of Tempe's administrative and court processes; specific time limits are not specified on the cited pages.
If in doubt about data sensitivity, contact the city before publication.

Applications & Forms

The city does not publish a required municipal form for API use on the cited municipal pages; access is typically via the portal interface and any portal-specific developer registration mechanisms.
