The Data score on cached tech stack APIs

This score, from 0 to 100, shows how many of a company's technologies the provider lists. For each company we called, we count the technologies the provider listed that a live API also listed. We divide that count by the most technologies any live API listed for that company. The result tops out at 100%. A technology no live API listed doesn't count, so a long list can't raise the score. We count a technology from a live API only if the company's website shows it or a second live API lists it. We leave out every other technology a live API lists. Sometimes only one live API finds a company. Then every technology a provider lists for that company counts. We divide by the most technologies any provider listed for it. When only one live API finds a company, we also score how many listed technologies come with details, like the date the company started using each one. A provider scores 0 on a company it didn't find. We count the technologies a company uses, but we don't score each technology's category or description. Each provider here answers from data it stored earlier. If a provider ran on fewer companies, we compare it with how the others did on those same companies. That way, easy companies can't raise its score.
