Reqistry - Find the right API.

What it does

Reqistry helps developers find the right API faster. Discover, compare, monitor, and organize 1,400+ APIs across 50+ categories with quality insights, reviews, and project collections. With Reqistry MCP, coding agents can also search and evaluate APIs directly while you build.

Discover, compare, monitor, and connect APIs, MCP servers, and agent tools. 1,500+ APIs across 50+ categories with trusted, continuously updated intelligence.

Reqistry helps teams and AI agents choose production-safe APIs, compare alternatives, track changes, and keep every project API stack fresh. The same trust-scored data everywhere you work — browse on the web, monitor from your phone, let agents query it, or build on the raw JSON. Search and compare every API with full trust signals — no install needed. Save APIs into project stacks and get downtime alerts on the go. 49 tools so coding agents can research, vet, and swap APIs in-session. Search the catalog, inspect trust signals, save APIs into projects, and track changes without opening a dozen docs tabs. Filter 3,548 APIs by category, auth, pricing, CORS, and live health — on the web, in…from reqistry.dev

  Sourcerer – MCP for semantic code search that reduces token waste2025 · github.com · ▲9

  I built this because I got tired of watching Claude Code read through massive files just to find a few functions. Sourcerer lets AI agents search code semantically and grab exactly the code chunks they need instead of burning tokens on whole files. It uses tree-sitter to parse your codebase and creates a searchable index. So instead of "read auth.py (538 lines)", an agent can search for "user authentication logic" and get back just the relevant functions.

  Keenable – A different web search API for AI agentsAug 2026 · keenable.ai · ▲12

  Hey HN! We built https:&#x2F;&#x2F;keenable.ai, a different web search API for AI agents. Keenable searches our own 100B+ page index. We are focused on low cost and latency (p95 <250ms from us-east). We don’t believe in benchmaxxing, so we open-sourced our internal benchmarking suite, NEEDLE (available at https:&#x2F;&#x2F;keenableai.github.io&#x2F;needle): a live benchmark that compares Keenable with other search APIs on fresh agent-like queries. I spent seven years at Amazon as a scientist working on web grounding for Alexa&#x2F;AGI, and my co-founder Andrey previously led search at…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
