TradeCheck

TC Contractor license checks for Oregon and Washington, with one verdict per check.

TradeCheck copies the open license data of each state every night and answers from that copy, so a check is one fast lookup, not a scrape of a state portal. Each record carries the days until the license, bond and insurance expire, plain flags, and a link to the state's own lookup. TradeCheck answers only keys that certified the FCRA terms (section 6.1 of the API Terms of Service): check the TradeCheck box at sign-up, or certify an existing key on Manage your key.

What it answers

Is this contractor's license active, restricted, inactive, not found or ambiguous?
When do the license, the bond and the insurance expire?
Did the state stop listing a license type, or suspend or revoke one?
Which contractors match a name, a city or a ZIP code?
