If you can hit a REST endpoint, you can pull Kalshi odds. Three steps, no scraping, no captcha headaches, no IP rotation.

01

Get your API key

Request a demo, scope your usage, and we issue a key scoped to Kalshi plus any other books you need. Trial keys available for evaluation.

02

Hit the endpoint

A single GET on /api/markets returns Kalshi markets for the league and periods you specify. Filter by bet_types, is_live, include_alts, and book_ids — same shape as the docs.

Why pull Kalshi via Betstamp

Stop scraping Kalshi. Start trading off it.

Scraping Kalshi is a maintenance tax — captcha walls, IP bans, schema changes, and the constant risk of your scraper breaking the night before an NFL Sunday. We do that for you, at scale.

Free your engineers from Kalshi scraping

Running your own Kalshi scraping infrastructure means engineering headcount tied up in captcha rotation, IP rotation, schema patches, and on-call. Pulling Kalshi via Betstamp moves that cost off your payroll — your engineers spend their time on model work and edge research instead.

True Line benchmark in the Odds Screen

The Betstamp PRO Odds Screen ships with our True Line fair-value side-by-side with every Kalshi price, so traders don't have to compute consensus from scratch. CLV-tested across 5+ seasons.

One call. Every book.

The /api/markets endpoint takes a book_ids parameter — comma-separate Kalshi alongside Bet365, FanDuel, DraftKings, BetMGM, Caesars / William Hill, BetVictor, Ladbrokes, Betway, and any other book in your subscription. One call returns all of them in one normalized schema.

Handles Kalshi's market structure for you

Player names, prop ladder alignment, line types, alternate sets, market grouping — all already normalized. Your model sees a consistent schema regardless of how Kalshi restructures markets.

Same Kalshi data, screen or API

Pull Kalshi into the PRO Odds Screen, the sportsbook API, or both — same pricing, same refresh rate, same normalized schema. Pick the delivery that fits your stack, switch later if it changes.

SLA, support, and zero scraper babysitting

99.99% uptime SLA on the Kalshi feed. Slack channel with our trading desk. Schema changes upstream don't break your pipeline — we handle the maintenance.
