   Hi HN! We’re Abhilash Chowdhary, Chris Pisarski and Manmohit Grewal. We built Crustdata (YC F24). Today we’re launching our web search API for AI agents, which not only returns the most relevant documents from the web but also maps them to the correct entity (person, company or event). Demo video here https://youtu.be/IouWW97hBN8 If you run agents at scale, tokens become a line item. The web data is the worst input: long pages, repeated content, mixed entities, stale claims. The usual web search -> scrape -> summarize + structure forces the agent to spend tokens doing…

   Hello, My name is Yahia, I've been working on scraping products for a long time and maintain a couple of free sites in my spare time (E.g. knifegeek.io) What prompted this is i've rebuilt scraping infra at every company I've started and finally just made it a product. Pass a URL, get clean markdown, html, images, sitemap or pass a domain, get logos, colors, socials, industry data. Goal is to offer a better service than VC funded competitors at a fraction of the cost. Stealth is included and automatic at no additional cost (normally an upcharge by alternatives). Would love your honest thoughts.

    APIRank.dev – We crawled and ranked public APIs from the internet▲176

    tl;dr we at Escape (YC W23), we scanned 5651+ public APIs on the internet with our in house feedback driven API exploration tech, and ranked them using security, performance, reliability, and design criteria. The results are public on https://apirank.dev. You can request that we index your own API to the list for free and see how it compares to others. Why we did that? During a YC meetup I spoke with a fellow founder that told me how hard it was to pick the right external APIs to use within your own projects. I realized that most of what we build relies on public APIs from external…
