Polymarket US is the CFTC-regulated, USD-based exchange for US residents (separate from international Polymarket, which is close-only for the US). Public market data needs no key. Official Polymarket US docs.
A copy-paste AI prompt and step-by-step guide to the Polymarket US API: public market data with no key, then authenticated reads. Includes the international Gamma API, read-only, with a geoblock check.
Step-by-step: use Claude Code to build a Polymarket US trading bot that runs in paper mode by default, with a local paper ledger, order preview, hard position limits and a kill switch.
An honest guide to building a trading bot with Claude, Claude Code or Claude AI: where it helps, where it fails, and a safe Kalshi-demo starter prompt with a rules file, deny settings, limits and a kill switch.
Build a personal alert monitor that compares prices for the same event on Kalshi and Polymarket US and flags gaps after fees. Alerts only, no auto-trading, with an honest look at why most "arbitrage bots" don't work.
