Open data
Public machine-readable datasets for researchers, reporters, partners, and AI systems. These feeds only include what we actually publish or explicitly map, and they intentionally keep suppressed rows out.
Published open-data feeds are available under CC BY 4.0.
Contractor profiles dataset
30074 public profiles with 390104 suppressed rows kept out of the feed.
License evidence dataset
16396 licensable public profiles with state-linked vs. lookup-required evidence states.
License-verification coverage dataset
382,870 contractors with a verified-active state-board license across 25 ingested states (423,346 matched incl. expired/suspended), plus the official license-lookup directory for all 51 jurisdictions. "Verified-active" applies only to the rostered states — the directory is where to verify yourself, not a verified roster. Computed live.
City taxonomy dataset
150 public city pages plus 40 observed service-area cities.
Permit offices dataset
14 permit offices and trade-level permit notes for the Ohio footprint we publish today.
Real Cost Index dataset
3,411,397 real building permits across 50 metros and 31 states → median + interquartile (P25–P75) cost benchmarks for 25 trades (computed live). A declared-value median, not a pure price index.
Cost Trends dataset
53 fixed-panel permit-value trend series across 12 metros for 2018–2025 (computed live).
By the Numbers (directory self-stats)
The directory's own aggregate statistics — vetted pros, board-verified-active licenses, Real Cost Index coverage, computed studies, and agent-callable tools — each computed live and cited to its loader.
Usage terms
Every published feed is free to use — commercial use included — under CC BY 4.0, which requires attribution to ProFix Directory with a link back to the source page. Numbers are computed live from real public records and refreshed as the underlying boards and permit datasets update. Provided as-is, with no warranty: a license or permit record is a point-in-time snapshot, so confirm current status at the official source before relying on it.
