## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delaware-business-license-search-d4aa7b3e
```

Example prompt: Can you look up the Delaware business license for 'DuPont' — I want to see their license number, category, current validity dates, and registered address in Wilmington?

## When to prefer this

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).

## Known failure modes

- 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

## 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.
