OpenFEMA

OpenFEMA is FEMA's open data platform, publishing free, public, machine-readable datasets on disaster declarations, public assistance grants, hazard mitigation projects, the National Flood Insurance Program (NFIP), and emergency alerting through a read-only RESTful API. The API uses OData-style query string parameters ($filter, $select, $top, $skip, $orderby) over individually versioned dataset endpoints, requires no API key or subscription, and returns JSON, CSV, or Parquet.

OpenFEMA publishes 7 APIs on the APIs.io network, including Catalog API, Disaster Declarations API, Hazard Mitigation API, and 4 more. Tagged areas include Government, Open Data, Emergency Management, Disaster, and FEMA.

OpenFEMA’s developer surface includes documentation and 4 more developer resources.

Where this information came from

This is an independent, third-party profile of OpenFEMA, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
