Public records, easier to use

These tools help people and their AI assistants check public records, with sources and dates alongside the results.

The services are in beta and currently free to use. Features, access and pricing may change as they develop. Each site describes its current coverage; privacy and terms are shared across all of them.

Plumbline

Check a contractor's license before you hire, from state licensing records.

CounterScript

Drug-price benchmarks from federal records, to help you compare a cash price.

GroundTruth

What's near an address: Superfund sites, toxic releases, enforcement-flagged facilities, drinking-water violations, from federal records.

GreenLight

Whether plug-in balcony solar is legal where you live, in plain language, with a signup for a certification alert.

Overassessed

Whether a Maryland property assessment is fair compared with genuinely similar homes, with appeal windows if it isn't.

GroundRules

Which federal, state, county and city laws apply at an address, with the text of the law and its citation.

For developers and AI assistants

Every product serves /llms.txt, a JSON API under /v1/, and an MCP endpoint at /mcp (registry namespace ai.agentlookups/*). A paid historical-weather API lives at weather.agentlookups.ai.

Using these with Claude, ChatGPT and other assistants: how to connect each service, read its answers and fix problems.
