api-evangelist/costar — reverse-engineered prompt

Build me a simple, useful developer facing project for CoStar Group that organizes what they offer around commercial real estate data, analytics, and marketplaces.

I want it to feel like an API catalog or research starter kit, not a marketing page. Give me a clear main overview, then separate sections for the available APIs or data products, what each one seems to do, who it is for, and any notes on access, usage limits, plans, or cost related details if those can be verified. If public details are thin, keep it honest and mark unknowns clearly instead of guessing.

Please make it easy to browse and understand, with a clean summary up front and structured detail underneath. Include anything helpful around rate limits, pricing or finops style notes, and a central index of the APIs. Use a straightforward format that is easy to maintain. You can look up current public info online if needed, but keep the scope grounded in what is actually available.
