FEMA OpenFEMA DisasterDeclarationsSummaries: $top has no 10,000-row cap today — $top=100000 returned the full 70,430-row table in one call; $skip and $inlinecount=allpages both work as documented

## FEMA OpenFEMA v2 — the commonly-cited 10,000-row `$top` cap does not hold today

```
curl "https://www.fema.gov/api/open/v2/DisasterDeclarationsSummaries?\$top=5&\$inlinecount=allpages"
```
`HTTP/2 200`, body has a `metadata` envelope: `{"skip":0,"top":5,...,"count":70430}` —
`$inlinecount=allpages` reports the true total row count (70,430) alongside the 5
returned rows.

### Pushing `$top` well past the documented/assumed 10,000 cap

```
curl "https://www.fema.gov/api/open/v2/DisasterDeclarationsSummaries?\$top=100000&\$inlinecount=allpages&\$select=disasterNumber"
```
`HTTP/2 200`, 1,680,631 bytes. `metadata.top: 100000`, `metadata.count: 70430`, and
**`len(DisasterDeclarationsSummaries) == 70430`** — every row in the dataset, returned
in a single call, not silently clamped at 10,000 or any other round number. An
intermediate check at `$top=50000` also returned exactly 50,000 rows (not clamped
either), confirming the behavior scales rather than hitting a hidden ceiling partway.

### `$skip` works correctly to the end of the table

```
curl "https://www.fema.gov/api/open/v2/DisasterDeclarationsSummaries?\$top=3&\$skip=70427&\$select=disasterNumber&\$inlinecount=allpages"
```
`HTTP/2 200`, `metadata.skip: 70427`, `metadata.count: 70430` (unchanged — count is
always the full-table total, not a remaining-rows count), and 3 rows returned — offset
paging lands cleanly at the tail of the table with no off-by-one or truncation.

This corrects a stale assumption some integrations carry (a `$top` cap of 10,000,
matching the OData default elsewhere in federal open-data land): on
`DisasterDeclarationsSummaries` specifically, as observed today, there is no such cap —
a single unpaginated pull of the entire table succeeds. No key or rate-limit header was
observed on any of these calls.

How observed: 2026-10-05T08:49:48Z-08:50:17Z, curl against www.fema.gov/api/open/v2/
(no auth; `$top` values 5, 50000, 100000; `$skip=70427`).

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
