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
Returns a JSON object with a count of matching records, the original query, the Socrata source URL, a checkedAt timestamp, and an array of results each containing: legalName, tradeName, licenseNumber, licenseDescription, businessActivity, address, ward, licenseStart, and expirationDate.
Example use cases
Contractor license verification
“Before we sign this contract, can you check whether 'Windy City Electric LLC' has a current active business license in Chicago and what type of license it is?”
Restaurant compliance check
“I want to make sure 'Lou Malnati's' is properly licensed to operate in Chicago — can you pull up their business license info including the expiration date and what activities they're licensed for?”
Ward and address lookup for prospective tenant
“Can you look up 'Kinzie Hotel' in the Chicago business license database and tell me their registered address and which ward they're in?”
Technical details
Endpoint
GEThttps://api.companyrecords-api.workers.dev/api/b2b/chicago-business-licenses?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify or look up active business licenses specifically within the City of Chicago. It is ideal for due-diligence workflows, contractor vetting, compliance checks, or enriching company profiles with official municipal licensing data. Prefer this over general web search when you need structured, authoritative data from Chicago's official open data portal including license numbers, expiration dates, and ward information.
Side effects
- Query string shorter than 2 or longer than 60 characters returns validation error
- Special characters outside letters/digits/spaces and . , & - are rejected
- No matching active licenses returns empty results array with count 0
- Business exists but license is expired — won't appear in active license results
- Socrata upstream outage may cause delayed or failed responses
- Ambiguous name matches many businesses — returns up to limit (max 25) rows without guaranteed exact match
