The honour system
Like Troy's list: if you're just poking at it, it's free. If you're building a product on it, embedding it in CI for a paying employer, or reselling the answers — buy a key. The free tier genuinely covers anyone playing around. The paid tier covers everyone pretending they weren't going to use it commercially anyway.
Specimen catalog content is curated from public postmortems and remains freely browsable. Paying for a key buys throughput and our goodwill, not access to the exhibits — the museum doors stay open.
