Capabilities

Tools 8

check_solar_quote

Where a solar quote's price falls among what homeowners in the same city paid for a system of the same size (Berkeley Lab records, homeowner-owned systems, no battery, before incentives): a percentile, the local typical price and range, and the quote's price per watt.

Discovered
find_contractors

Contractors ranked by how many jobs of this kind their city permit record shows. Returns name, license where the state publishes one, job count, typical stated job value, the ZIP codes they work in most, and a profile URL. Ranking is by volume on the public record, not quality or reviews.

Discovered
generator_size

The smallest common home standby generator size, with 10% to spare, for the things that must run in an outage: running watts plus the biggest motor's start. Also what generator permits stated as job value, by size, where a city has enough of them. Typical appliance figures; an electrician's load calculation beats them.

Discovered
list_coverage

Which cities and kinds of work contractors.fyi covers, with the dates each list covers. Call this before the other tools to get valid city and kind_of_work values.

Discovered
permit_timeline

Days from permit application to issue, and from issue to final inspection, from the dates on city permits, with the number of permits and the dates they cover. Final-inspection times count finished jobs only.

Discovered
project_cost

What city permits for this kind of work stated as the job value: median and middle half, with the number of permits and their dates. Give a ZIP to get that ZIP's figure where the site publishes one. The value stated on the city permit, not the price paid.

Discovered
search_contractor_records

Look a contractor up by business name across every city covered: the city, how many permitted jobs are on its record there, and its profile URL. This searches the permit record; it does not verify a license today.

Discovered
solar_estimate

Size a home solar system from the monthly electric bill (or its kWh, or, with neither, the home and what runs on electricity), plus anything the home plans to add such as electric cars, then give the price range homeowners in that city paid for a system that size (Berkeley Lab records, before any tax credit, no battery), yearly savings and payback. Output per kW, heating and cooling use and the default price per kWh are rough city figures.
