🧾 JSON sample record

One real record from run RFG6OkcyObcOVfpiS (emails/phones masked, long text shortened):

{
  "guidance": true,
  "data_source": "guidance",
  "message": "Live Japan 法人番号 (Corporate Number) registry data requires a FREE NTA Web-API application ID. Register at https://www.houjin-bangou.nta.go.jp/webapi/ and pass it as `nta_api_key`. No charge is made for this guidance row.",

💰 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).
Corporate record (corporate-record)	$0.03	Per NTA Houjin Bangou corporate registry record

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 × $0.03 = $3.00 plus the start fee.
