How this service works
The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.
Output
Returns structured company data sourced from the Polish KRS registry, including legal name, registration status (active/inactive), legal form, registered address, names and roles of directors or authorized representatives, share capital, date of incorporation, and PKD business activity codes. Each call also includes a cryptographically hashed audit record for compliance traceability.
Example use cases
Vendor due diligence for procurement
“Before we sign a contract with this Polish supplier, can you look up their KRS number 0000544220 and confirm they're an active registered company with their current registered address and legal representatives?”
Onboarding a Polish business client
“We're onboarding a new B2B client in Poland — their KRS number is 0000217580. Can you fetch their official company details from the KRS registry so we can verify their legal name, status, and directors?”
Compliance check on Polish counterparty
“I need to run a quick compliance check on a Polish company — KRS number 0000039761. Pull their KYB essentials so I can see their legal form, registration status, and registered office address.”

Endpoint
POSThttps://api.strale.io/x402/v2/solutions/kyb-essentials-plWhen to prefer
Choose this endpoint when you need structured, authoritative KYB data specifically for Polish companies registered in the KRS (Krajowy Rejestr Sądowy). Prefer it over generic business search APIs when you have a specific KRS number and need official registry data with a verifiable audit trail. It is distinct from Austrian Firmenbuch or other country-specific endpoints on the same platform.
Side effects
- Invalid KRS number format — returns validation error
- KRS number not found in registry — returns 404 or empty result
- Registry temporarily unavailable — upstream timeout error
- Malformed request body — returns 400 bad request
- Insufficient payment or x402 payment failure — returns 402
