I've been building a certification intelligence tool for hardware teams (markready.io) and needed a good test lab directory. The FCC publishes accreditation data through a Socrata API but it's pretty bare - names, addresses, designation numbers, and expiration dates that are often years stale. No websites, no capabilities, nothing to tell you whether a lab is a two-person shop or an Intertek subsidiary.

The first thing I did was build an LLM-maintained wiki about the hardware certification universe - FCC rule parts, equipment authorization types, test standards, the TCB system, international equivalents, all of it. About 30 pages of structured knowledge that Claude could reference when doing the actual enrichment work. Then I ran a loop of subagents over multiple days to enrich the labs - pulling from the Socrata API, cross-referencing TCB registrations to see which labs can certify (not just test), hitting Google Places for websites and coordinates, crawling accreditation body directories to figure out which labs are actually still active. The FCC's own expiration dates are useless for this - tons of labs show 2022 or 2023 dates but are clearly still operating. Claude synthesized the descriptions and capabilities from all the scraped data into structured records, using the wiki as context.

The directory is at markready.io/labs. You can browse by country, US state, and TCB status.

Today's an interesting day to launch this because the FCC is voting to ban all 126 test labs in China and Hong Kong. Not just the government-controlled ones they banned last year - all of them. 21% of the global total gone. 27 of those 126 are Western firms (Intertek, SGS, TUV, UL) operating China offices. I wrote up the full impact analysis at markready.io/blog/fcc-bad-labs-vote.

Full disclosure: I've never actually gotten a device through FCC certification myself. I've been building RF hardware since I was a kid but always on the hobby side. What pulled me into this was the data problem - the FCC publishes all this information but nobody had stitched it together into anything usable, and it felt like a genuinely interesting dataset to enrich and a real gap in understanding the hardware product space.

Built with Next.js + Cloudflare. The enriched dataset covers 28 countries.

Does this increase or decrease demand for your tool? Less fragmentation would be expected to decrease demand from insiders. But more regulatory scrutiny would raise the stakes for outsiders getting it wrong.
