Denver Open Data API Access and Publication Bylaws

Technology and Data Colorado 3 Minutes Read ยท published February 07, 2026 Flag of Colorado

Denver, Colorado maintains a public Open Data Portal to publish municipal datasets and provide API access for developers, researchers, and the public. This guide summarizes the portal access model, dataset publication rules, responsible offices, and practical steps to request, publish, or appeal decisions related to city datasets. It explains compliance expectations for departmental data stewards and how members of the public can request data or report issues.

Overview

The City and County of Denver publishes datasets on its official Open Data Portal to improve transparency and reusability. Departments that collect or produce public data are expected to prepare datasets with clear metadata, licensing, and update cadences. The portal uses a managed platform for hosting, APIs, and dataset cataloging; see the official portal for dataset listings and platform guidance Denver Open Data Portal[1].

Confirm dataset sensitivity and privacy clearance before publishing.

Publication Rules and Responsibilities

Departmental data stewards must follow city policies for metadata, fields, and redaction of personal or sensitive information. Publication rules typically include:

  • Metadata that describes fields, update frequency, and contact steward.
  • Standardized field names and schemas where required by city programs.
  • Redaction or withholding of non-public or legally protected information.
  • Declared update schedule (daily, weekly, monthly, or ad hoc).
Publication must not expose personally identifiable information without legal authority.

Penalties & Enforcement

The official Open Data Portal and linked city guidance describe publication expectations and stewardship but do not list monetary fines or criminal penalties on the portal page itself; specific enforcement amounts are not specified on the cited page and should be confirmed with the enforcing office.[1]

  • Fine amounts: not specified on the cited page.
  • Escalation (first, repeat, continuing offences): not specified on the cited page.
  • Non-monetary sanctions: administrative removal of datasets, orders to redact, suspension of publishing privileges, or referral to legal counsel as described by department procedures.
  • Enforcer: departmental data steward and the city office that administers the Open Data program (see Help and Support for contacts).
  • Inspection and complaint: members of the public may report issues through official contact channels; the portal page provides contact details.[1]
  • Appeal/review: the process and time limits for appeals are not specified on the portal page and depend on the enforcing department or internal review procedures.
If you believe data was wrongly withheld, file a formal request with the responsible department promptly.

Applications & Forms

The portal provides mechanisms for dataset submission and API keys via its managed platform, but an official citywide single application form or fee schedule for publication or API access is not specified on the cited page; consult the portal or the administering office for platform-specific request pages and account registration.[1]
