Show HN: Things to Do API
I built an api/mcp for local events: pop-ups, one-off events, concerts, etc. currently covering the SF bay area.I've been building a bunch of consumer apps lately around personalization and recommendation and have had a hard time finding this data in one spot. agents can find useful stuff through tool calls / web search, but slow.you can scrape on demand too, but i wanted a faster data set and couldn't find an existing provider for the mix of event types I was searching for.the methodology for it is to find influential accounts/posters/etc. and do a fan out across things that they co-post with.mcp: `claude mcp add --transport http thingstodo https://api.thingstodoapi.com/mcp`I'm considering adding other cities. If you're building something that needs local event data, would something like this be useful and where would you want coverage?

Show HN: 500 clocks in one 6.3 MB HTML file by Opus 5.5
Lately I've been testing frontier models by having them create self-contained web pages that display clocks--sort of my personal version of Simon Willison’s pelican-on-a-bicycle metric.I have been particularly impressed by the variety, interest, and quality of the clocks created by Claude Opus 5.5. Over the course of several sessions in the Claude chat interface, I had it build a total of 500 clocks.Claude’s summary of the prompting process and page design is here:https://github.com/tkgally/500-clocks/tree/main
