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.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/fema: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
