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, pagination offset, the source URL used to query data.delaware.gov, a checkedAt timestamp, and an array of business objects — each containing business name, trade name, license number, license category, valid-from and valid-to dates, street address, city, state, ZIP, country, and optional geolocation coordinates.
Example use cases
Verify contractor license before hiring
“Before I hire this contractor, can you check if 'Brandywine Construction LLC' holds a valid contractor license in Delaware? I need their license number and whether it's currently active.”
Due diligence on a Delaware vendor
“I'm vetting a new supplier called 'Atlantic Trade Supply' — can you pull their Delaware business license record so I can confirm they're a licensed retailer and get their registered address?”
Find licensed businesses by city and category
“Can you find up to 20 businesses in Newark, Delaware that are licensed as general retailers? I want their names, trade names, and license validity periods.”
Technical details
Endpoint
GEThttps://api.companyrecords-api.workers.dev/api/gov/delaware-business-search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify or look up Delaware state business licenses issued by the Division of Revenue — specifically for businesses, retailers, contractors, and commercial lessors operating in Delaware. Prefer this over general business databases when you need official government data including license number, validity period, and license category. Note: this does not cover Delaware corporate entity filings (e.g. LLCs, corporations registered with the Division of Corporations).
Side effects
- No results returned if the business name spelling doesn't match the official filing (try partial name)
- Location coordinates may be null for some records
- Only revenue-licensed businesses are included — corporate entity filings from the Division of Corporations are not present
- Pagination may be needed for common name searches that exceed the default 20-record limit
- Daily data refresh means very recently issued licenses may not appear immediately
