Yolodex – real-time customer enrichment API
hey hn, i’ve been working on an api to make it easy to know who your customers are, i would love your feedback. what it does send an email address, the api returns a json profile built from public data, things like: name, country, age, occupation, company, social handles and interests. It’s a single endpoint (you can hit this endpoint without auth to get a demo of what it looks like): curl https://api.yolodex.ai/api/v1/email-enrichment \ --request POST \ --header 'Content-Type: application/json' \ --data '{"email": "[email protected]"}' everyone gets 100…
In plain words
Yolodex is an API that enriches customer data by accepting an email address and returning a JSON profile built from public information, including name, country, age, occupation, company, social handles, and interests. Designed for developers and businesses needing quick customer intelligence, it offers a single endpoint with straightforward integration. Users receive 100 free enrichments monthly, with additional lookups charged at approximately $0.03 per successfully enriched profile; failed searches incur no cost.

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
