Access notes

OpenFEMA is an anonymous REST API with an OData-style grammar: $filter, $orderby, $top, $skip, $select, $inlinecount=allpages, and $format=csv. No key or account is needed. The service returned 10,001 rows when asked for them and ignores $top=0, so a page size is a choice rather than a cap, and a count is asked for with $top=1.

A timestamp in a $filter must be a date alone: a full timestamp is compared against its own percent-encoded text and matches nothing, with no error. Check the filter echoed in the response metadata when a query comes back empty.

FEMA's rows are keyed by state and county FIPS codes and carry no coordinates, so its datasets are selected by a named place, not a box (ADR 0034). Dataset and field metadata, including each dataset's lastDataSetRefresh and recordCount, are themselves served at /api/open/v1/OpenFemaDataSets and /api/open/v1/OpenFemaDataSetFields. The terms and conditions ask for the endpoint and its version, the time of access, and a disclaimer, which usdata cite prints.

Other entries from this provider are planned.

Planned datasets are not fetchable

A planned entry describes a source the registry knows about but has no adapter for. Search shows it only with --include-planned, fetch exits 3, and the versions and targets page lists its status.
