How this service works
Pay-per-call company registry, government, legal and B2B data tools for AI agents, from official registers and public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.
Output
A JSON object containing the company's KRS number, NIP tax number, official name, legal form, registered seat city, full registered address (street, number, city, postcode), registration date, last entry date, extract state date, and the source URL from the Polish Ministry of Justice KRS API. Returns 404 if the KRS number is not found.
Example use cases
Due diligence on Polish supplier
“I'm vetting a Polish supplier before signing a contract — can you look up their company in the KRS register using number 0000777777 and tell me their legal form, registered address, and NIP tax number?”
Verify Polish business registration
“Can you confirm whether the Polish company with KRS number 0000123456 is currently registered, and when it was first registered and last updated in the court register?”
Enrich CRM with Polish company data
“We have a Polish client whose KRS number is 0000654321 — please fetch their official company name, registered seat, and NIP from the KRS register so I can update our records.”
Technical details
Endpoint
GEThttps://api.companyrecords-api.workers.dev/api/gov/krs-poland?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have a specific 10-digit KRS number for a Polish legal entity and need authoritative, current official data directly from the Polish national court register. Prefer this over generic business search tools when you need the official NIP, legal form, and registered address for compliance, due diligence, or data enrichment purposes. Not suitable for searching by company name — a KRS number is required.
Side effects
- KRS number not found or not registered returns HTTP 404
- Invalid KRS number format (not 10 digits) may return an error
- KRS API upstream unavailability may cause timeouts or 5xx errors
- Company in liquidation is still returned but name may reflect liquidation status
