Coinbase prices without a public API

Coinbase doesn't publish a public data API. Coinbase lists Kalshi sports contracts, so every Coinbase price is in Betstamp's Kalshi feed (book ID 194), pre-game and live, matched to the same events as 200+ sportsbooks with a fair-value line beside every market.

Know where Coinbase sits against the market.

Coinbase's prices mean more next to everyone else's. Betstamp puts them there.

Fair value per market

Where to quote, from sharp-book consensus: Betstamp's True Line, a no-vig price, sits next to every Coinbase price.

One call. Every venue.

The /api/markets endpoint takes a book_ids parameter — comma-separate Coinbase alongside Polymarket, Kalshi, ProphetX, Novig, bet365, FanDuel and any other book in your subscription. One call returns all of them in one normalized schema.

Matched events, not just prices

Coinbase markets are already matched to the sportsbook event and market, so you're comparing like with like.

Historical analysis

Every Coinbase record arrives in one stable schema, so you can store it from the day you subscribe and build your own historical Coinbase data for backtesting. In the PRO Odds Screen, see how each Coinbase price has moved on every market.

Same Coinbase data, screen or API

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

SLA and support

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

How Coinbase prices convert to odds

A contract at 62¢ implies a 62% probability. Decimal odds = 1 / 0.62 = 1.61. American odds = −(62 / 38) × 100 = −163. Before comparing with a sportsbook, strip the book's vig so both sides are fair probabilities — that's what Betstamp's True Line does for every market. Try it with the no-vig fair odds calculator.

FAQ

Coinbase API questions.

Does Coinbase have an API?

Coinbase lists Kalshi contracts, and Betstamp covers every one of them under Kalshi's book ID (194): live and pre-game prices, normalized next to 200+ sportsbooks, with cross-venue event matching and a fair-value line.

Can I get historical Coinbase data?

Yes, and every record is yours to keep. From the day you subscribe, every Coinbase price arrives in the same schema as live, so you can store it and build a complete historical Coinbase record. The PRO Odds Screen also shows how each Coinbase price has moved on every market. Betstamp doesn't provide backfills from before your subscription starts.

How do Coinbase prices convert to American odds?

Divide the contract price in cents by 100 for implied probability. For a 62¢ contract: 62% → decimal 1.61 → American −163. Betstamp returns decimal and American odds in every record.

Does Betstamp's Coinbase feed include sports only?

Betstamp's Coinbase feed is built for sports: moneyline, spread, total, player props, game props across 21 leagues, pre-game and live, with 1.4M+ market selections priced in the last 30 days and every one matched to the same event as 200+ sportsbooks.

Can I compare Coinbase to Polymarket / Novig?

Yes. Every venue is matched to the same events, so Coinbase, Polymarket and Novig prices sit in one response alongside the sportsbook line.
