Fresno Municipal Open Data API - Request Datasets

Technology and Data California 3 Minutes Read · published February 08, 2026 Flag of California

This guide explains how to request public datasets via the City of Fresno Open Data API. It covers locating datasets in Fresno, California, checking dataset metadata and licensing, requesting access or API support, and the departments that handle data and records requests. Use this procedure to submit technical API requests, request dataset exports, or report data quality and access issues. For legal or formal records requests about datasets, follow the city public records process and contact the City Clerk or IT help desk as noted below.[1]

Where to start

Begin on the City of Fresno Open Data portal and search by dataset name, keyword, or department. Review each dataset's metadata for API endpoints, rate limits, required API keys, and license terms before making automated requests.

Check metadata for API endpoints and license info before scripting requests.

How the API typically works

Most municipal open data portals expose REST endpoints and query parameters for filtering, sorting, and pagination. Identify the dataset identifier (resource ID) and test queries in the portal's API explorer or with curl. Respect published rate limits, attribution, and terms of use.

Penalties & Enforcement

The City of Fresno does not publish specific fines or penalty schedules for misuse of Open Data API access on the primary portal page; specific monetary fines are not specified on the cited page. Enforcement typically falls to the City's Information Technology department in coordination with the City Attorney and City Clerk for legal or records disputes.[1]

  • Fines: not specified on the cited page; contact the city for details.
  • Escalation: not specified on the cited page; escalation often moves from informal notice to account/API key suspension and then legal action if needed.
  • Non-monetary sanctions: possible suspension or revocation of API keys, takedown orders, or court actions (not specified on the cited page).
  • Enforcer and complaints: Information Technology and City Clerk handle technical and legal complaints; file an official report or contact IT support as listed below.
  • Appeals and review: specific appeal routes and time limits are not specified on the cited portal page; formal records appeals follow city clerk procedures.
If you receive an enforcement notice, contact City IT or the City Clerk promptly to learn appeal deadlines.

Applications & Forms

The Open Data portal does not publish a dedicated "API request" application form; technical requests are typically handled via support email or portal contact. Formal public records requests use the City of Fresno public records procedures and any available forms on the City Clerk page (see Resources). If a fee or formal application is required for a large data export, that fee is not specified on the portal page.[1]

Action steps to request a dataset

  • Identify the dataset and resource ID on the Open Data portal.
  • Review metadata for API endpoints, schema, license, and rate limits.
  • Test queries via the portal API explorer or a simple curl request.
  • If access or data quality issues persist, contact City IT or the dataset steward listed in the dataset metadata.
  • For formal records or withheld data, submit a Public Records Act request to the City Clerk as required.
Start with the dataset metadata — it usually states the API resource ID and contact person.

FAQ

Do I need an API key to access Fresno's Open Data API?
It depends on the dataset and portal settings; check the dataset metadata for rate limits and API key requirements, or contact City IT for clarification.[1]
Can I commercialize data obtained from the City Open Data API?
License terms vary by dataset; review each dataset's license in its metadata. If no license is listed, contact the dataset steward or City Clerk to confirm reuse permissions.[1]
How do I report incorrect or incomplete data?
Report issues to the dataset steward listed in the metadata or to City IT; for unresolved disputes, file a formal complaint with the City Clerk's office.[1]

How-To

  1. Open the City of Fresno Open Data portal and search for the dataset you need.
  2. Open the dataset page and copy the dataset resource ID or API endpoint shown in metadata.
  3. Use the portal API explorer or a REST client to test a sample query and verify results.
  4. If results are incomplete or access is blocked, contact the dataset steward or City IT support.
  5. For withheld information or formal records, submit a Public Records Act request to the City Clerk.
Testing queries in the portal's API explorer helps avoid rate-limit or schema errors.

Key Takeaways

  • Always check dataset metadata for API endpoints, licensing, and contacts.
