Ask HN: Recommended technographic API?

Does anyone know of any good technographic APIs? I run a dev consultancy and basically want to know what tech stack they currently use (ie what they use for CI/CD or security), so it can help me prepare when i talk to a prospect. I know Builtwith is the leader in this space but i feel its lacking a bit when it comes to finding tech that isnt front end or JS focused.

I’ve tried using the Anthropic API but most of the time it seems to give me hallucinated results (based on the results for companies I know their tech stack)

Ideally something that doesnt cost an arm and an leg :)
