Real rows from run VZYCoU4hfHPSqRpey on build 0.0.5 (2026-09-25), unedited apart from masked emails/phones and shortened long text; fields the source does not publish are empty.

⚙️ Sample inputs

This is the Store example input — the same input Apify's automated check runs — so it is proven to return rows on the current build. Paste it into the input form, or send it through the API, CLI or a schedule:

{
  "service_code": "WS",
  "license_class": "any",
  "event_type": "any",
  "days_back": 30,
  "max_events": 100
}

🔧 Input reference

Field	Type	Default	What it does
service_code	string	""	FCC ULS service code to filter by. Examples: HA (Amateur), IG/PW/YG (Land Mobile Business & Public Safety), CL (Cellular), PC (PCS), AW (AWS), WS (Wireless Communications), PG (Pa…
state_filter	string	""	Two-letter US state code to filter licensee addresses (e.g. 'CA', 'TX', 'NY'). Leave empty for all states.
license_class	string (common_carrier, private_radio, broadcast, any)	"any"	License classification family. 'common_carrier' = Part 22/24/27 cellular/PCS/AWS carriers; 'private_radio' = Part 90 land-mobile/business radio; 'broadcast' = Part 73/74 broadcast…
event_type	string (new_license, renewal, cancellation, modification, any)	"any"	ULS license-event type filter. 'new_license' = newly granted; 'renewal' = renewed call sign; 'cancellation' = canceled/terminated/expired; 'modification' = license modification (e…
days_back	integer	30	Look-back window in days. The FCC keeps seven days of daily ULS transaction files online, so the live window is capped at 7 days; larger values are accepted and reported honestly…
max_events	integer	100	Maximum number of license events to emit. Hard ceiling — actor stops scanning after this many records are pushed. Lower this for cost control on large service codes.

🧾 JSON sample record

One real record from run VZYCoU4hfHPSqRpey (emails/phones masked, long text shortened):

{
  "license_id": "KG5OMB",
  "licensee_name": "Simpson Jr, Robert D",
  "frn": "0025734815",
  "license_status": "ACTIVE",
  "event_type": "new_license",
  "event_date": "2026-09-18",
  "service_code": "HA",
  "service_name": "Amateur Radio",
  "frequency_range": "1.8 MHz – 250 GHz (multiple bands)",
  "location_state": "NM",
  "license_expiration": "2036-07-13",
  "_source": "uls_daily"
}

💰 Pricing

Event	Price (USD)	When it is charged
Actor Start (apify-actor-start)	$0.005	Charged when the Actor starts running. Number of events charged depends on Actor memory (one event per GB, minimum one event).
License event (license-event)	$0.08	Per FCC ULS new license, renewal, cancellation, or modification event

Pay-per-event: you pay only for what the run delivers. A run that delivers nothing bills no result events (only the actor-start event, when the actor defines one). Example: a run that delivers 100 results costs 100 × $0.08 = $8.00 plus the start fee.

📊 What you get

Clean JSON, one record per license event (11 fields):

• license_id — call sign (or ULS unique system id when no call sign is assigned)
• licensee_name — licensee entity name
• frn — FCC Registration Number
• license_status — ACTIVE / EXPIRED / CANCELLED / TERMINATED …
• event_type — new_license, renewal, cancellation, modification
• event_date — ULS last-action date (ISO)
• service_code — ULS radio service code (e.g. HA, PW, PC)
• service_name — human-readable service name
• frequency_range — representative band for that service
• location_state — licensee state
• license_expiration — license expiration date (ISO)

🗓 Coverage

The FCC publishes one daily transaction file per service group and keeps the last seven days online, so this actor's live window is the last 7 days of license activity. Ask for a longer days_back and the run states the window it actually covered in its status message.

💵 Pricing

Pay-per-event: $0.08 per license event delivered (license-event), plus the platform's Actor-start charge of $0.005 per GB of run memory. Rows are charged only when a real FCC record is delivered — a run that finds no matching events charges nothing, and a run that cannot reach the FCC fails instead of delivering filler.

🤖 Use with AI agents

Point Claude, the OpenAI Agents SDK, an n8n flow or any MCP-aware client at it and pull official records on demand.

Agentic payments (x402): Supports agentic payment via x402 — agents can call this actor with USDC, no API key required.
