A live crypto price ticker on a static site, three ways

12+ hour, 12+ min ago   (635+ words) I run a small static site on Netlify and wanted a scrolling price ticker across the top. No build step, no server, and ideally no signup. Here is what I tried and where each one hurt. The shortest path is…...

Holdout Ledgers Keep Agent Scores Honest

19+ hour, 16+ min ago   (1654+ words) A headline agent percentage is not a measurement until the task ledger, metrics, and controls can be re-run by a stranger. Teams that skip that freeze often publish marketing numbers dressed as evaluation, then discover they cannot reproduce the run....

9 Free Endpoints I Built Into a Financial Data API — With Curl/Python Examples

2+ day, 2+ hour ago   (453+ words) I've been building XFINLAB, a financial intelligence API — market events, sentiment, technical analysis, macro data — with an MCP server for AI agents on top. Along the way I also built a handful of free, no-key tools directly into the site....

One rounding, not many: why a provably-fair verifier must match the server bit for bit

2+ day, 8+ hour ago   (420+ words) Originally published on the Betkyo Journal, where every figure is read from the game engine's source. A hash is thirty-two bytes. A game needs a number between 0 and 1. The obvious way to get one is to read some of the…...

How I Built a Free Real-Time Solana Token Scanner with Next.js

4+ day, 21+ hour ago   (297+ words) Every time I found a promising new Solana token, it was already too late. By the time I discovered it manually on DexScreener, early buyers had already made 5–10x. I needed a way to see new tokens the moment they launched…...

Building a Polymarket TWAP State Machine for Trading Bots

4+ day, 22+ hour ago   (709+ words) Learn why a Polymarket TWAP state machine should model resolution, oracle observations, market time, and execution as separate states.

Networking Needs a Protocol: Build a Consent-First Community Introduction Flow

4+ day, 22+ hour ago   (800+ words) Networking advice often assumes the difficult part is finding the right words. In a community product, the harder problem is usually uncertainty: That ambiguity can feel like a confidence problem, but part of it is a protocol problem. A better…...

I made an API that has no signup, because the payment is the login

5+ day, 10+ hour ago   (490+ words) I wanted an agent of mine to resolve an Australian company by its ABN. That is a solved problem. There are several APIs that do it and they are cheap. The agent could not use the ones I found. So…...
