Mode

mode

Optional

What this run does. watch: establish (first run) or advance a standing filter-watch and deliver newly-recognized organizations. unwatch: forget a saved filter's memory. list-events: replay this filter's prospect history. report: one-off new-determination cohort for a state/subsection/NTEE/period (billed once, $15).

Type:string

Default:watch

Options:

watchunwatchlist-eventsreport

States

states

Optional

US states/territories to watch, as 2-letter USPS codes matched against the IRS STATE column. At least one is required for a watch; report may be broad (leave empty for all states). Up to 10.

Type:string[]

Max. items:10

IRS subsection

subsection

Optional

Which 501(c) subsection to watch, matched against the IRS SUBSECTION column. The default and primary use case is 501(c)(3). Choose 'all' to watch every subsection.

Type:string

Default:03

Options:

03040619all

NTEE mission codes (optional)

nteeCodes

Optional

NTEE prefixes matched against the IRS NTEE_CD column. A single letter like P (Human Services) or E (Health Care) matches the whole major group; a longer prefix like B82 narrows further. Leave empty to watch all missions.

Type:array

Max prospects per month

maxAlertRowsPerMonth

Optional

Per-account monthly ceiling on delivered prospects. Past it the run withholds the rest and delivers an uncharged notice instead, so a broad all-mission state filter cannot surprise-bill you. Withheld prospects redeliver next month.

Type:integer

Minimum:500

Maximum:100000

Default:1000

Max monthly volume spend (USD)

maxMonthlySpendUsd

Optional

A money cap on cumulative volume-tier ($0.02) charges per filter-month. Whichever monthly cap trips first (this or Max prospects per month) stops charging. Does not include the $9 watch fee.

Type:integer

Minimum:0

Maximum:100000

Default:40

Max prospects per run

maxAlertsPerRun

Optional

Hard cap on prospects delivered in a single run. Any overflow is not marked seen and redelivers on the next run, with a truncation notice naming how many were withheld. Bounds a long-gap catch-up run.

Type:integer

Minimum:1

Maximum:2000

Default:1000

Webhook URL (optional)

webhookUrl

Optional

Optional https URL that receives a POST with the new prospects after each run. Best-effort alerting only: the dataset is the durable record. If you need to verify the caller, put a secret token in the URL yourself.

Type:string

Filter name

filterName

Optional

Names this filter within your account so its deduplication memory persists across scheduled runs. Lowercased, letters/digits/hyphens only (1 to 40 characters). Widening a saved filter under the same name re-baselines it (no back-catalog charge).

Type:string

Default:default

Report period (report mode)

period

Optional

Report mode only. The RULING (determination) month window for the cohort, as YYYY-MM (a single month) or YYYY-MM..YYYY-MM (an inclusive range), for example 2026-04..2026-06.

Type:string

Dry run (preview, no PPE charge)

dryRun

Optional

When true, stream, filter and diff but return at most 5 preview rows. It charges no PPE event and writes no saved filter, billing or event-history state, but the preview rows are still written to your dataset/OUTPUT. Use it to sanity check your filter before scheduling. A dry run still downloads and streams the full extract (about 343 MB, 327 MiB; measured at 342,745,263 bytes), so ordinary Apify platform compute, storage and egress usage still applies.

Type:boolean

Default:false
