How this service works
Stop scraping Japanese government and public-data sites. Call clean Japan payroll, company, and grant APIs over one host. Preview free; one public marketplace listing covers all current products; x402 direct is available for agent-native buyers.
Output
A JSON response containing enriched structured records for each submitted entity, including clean Japanese government-sourced data fields such as payroll figures, company details, and grant information.
Example use cases
Verify supplier credentials across Japan
“I have a list of 15 Japanese suppliers we're considering. Can you batch-check them against government records using kasanegi to confirm their payroll size, company registration, and any public grant history?”
Identify Japanese grant-eligible companies
“We're looking to recommend government grants to our Japanese startup portfolio. Can you enrich our 20 portfolio companies with their public grant data and payroll info from kasanegi so we know which ones qualify?”
Audit Japanese contractor compliance
“Pull structured government data on these 8 Japanese contractors we work with — I need their current payroll records, company details, and any public grant information all in one batch using kasanegi instead of searching each site manually.”
Technical details
Endpoint
POSThttps://kasanegi.com/v1/enrich/batchWhen to prefer
Choose this endpoint when you need to enrich multiple Japanese entities in a single call rather than one at a time, saving on per-call costs and latency. Ideal when you have a list of Japanese companies, payroll queries, or grant lookups and want clean structured JSON without building scrapers against Japanese government websites. Prefer over single-entity endpoints when processing lists of 2 or more items.
