`fda_device_event_counts`

Pack: fda-devices · Endpoint: https://gateway.pipeworx.io/fda-devices/mcp

Aggregate MAUDE reports for a device query by event type, manufacturer, product code, or receive date. Counts reflect reporting and database artifacts—not event rates or causal risk—and must not be compared without exposure denominators.

Parameters

Name	Type	Required	Description
`query`	string	no	Optional raw openFDA MAUDE filter, e.g. ‘date_received:[20250101+TO+20261231]’. Omit to rank across all reports.
`count_field`	string	yes	What to rank by. For “which DEVICES had the most reports” use device.generic_name.exact (device type) or device.brand_name.exact (specific product).
`limit`	number	no	Buckets (1-100, default 20).
