Prediction Market and Crypto Options Data Providers Compared

If you've searched for an alternative to Tardis.dev, Amberdata, Lychee, PolymarketData.co, or CoinAPI, you've probably noticed something odd: none of them compete with each other directly. Tardis and CoinAPI won't show you a single Kalshi contract. Lychee won't show you a Deribit options chain. They're not really substitutes for one another — they're split across a line most people don't notice until they need data from both sides of it.

This compares all five on what they actually cover, what they cost, and how you access the data. Then it covers where that leaves you if your research spans both crypto derivatives and prediction markets.

The five providers, compared

Read across that table and the split is exact. Three providers do crypto derivatives and nothing else. Two do prediction markets and nothing else. There's no row where both columns are checked.

Tardis.dev: deep crypto tick data, no prediction markets

Tardis is built for people who need raw market microstructure, not summarized bars. It covers order book snapshots and incremental L2/L3 updates, individual trades, liquidations, options chains, funding rates, and open interest across more than 50 exchanges including Deribit, Binance, OKX, and BitMEX, with over 7 years of history and better than 99.9% completeness on its own numbers.

That depth comes at a price that puts it out of reach for a lot of independent researchers: four tiers running from roughly $350 to $6,000 a month depending on which data plan you need, with no free tier to test against. It's built for teams that already know they need tick-level crypto data and have budget for it. Kalshi, Polymarket, and every other prediction market are simply absent from the product.

Amberdata: institutional crypto and DeFi, no prediction markets

Amberdata covers spot, derivatives, and DeFi across more than 1,000 centralized and decentralized exchanges, plus wallet intelligence and lending-protocol data. Its client list, Citi, Coinbase, Nasdaq, Franklin Templeton, Nomura, tells you who it's built for: large institutions that need compliance-grade infrastructure, not an indie quant running a personal backtest.

There's a free tier for its derivatives analytics product, which is more than Tardis offers, but full pricing isn't published; getting a real number means talking to sales. Like Tardis, prediction markets don't appear anywhere in its coverage.

Lychee: Kalshi and Polymarket, no crypto derivatives

Lychee flips the gap the other way. It covers Kalshi and Polymarket, both historical and live, plus a set of reference and alternative data: Chainlink, Binance spot prices, CoinGecko, social signals from Twitter and Hacker News, and traditional sources like SEC filings and Treasury data. What it doesn't have is any crypto-derivatives coverage; Deribit and options data aren't part of the product.

It's priced for accessibility, $19.99 to $79.99 a month across three paid tiers plus a limited free demo, and built around a no-code experience: SQL builder, dashboards, charts. An API exists, but the product's actual center of gravity is querying without writing code, not integrating into a pipeline.

PolymarketData.co: Polymarket only, API-first

PolymarketData.co narrows the prediction-market side further: Polymarket only, no Kalshi. What it does cover, it covers deep — full time series back to August 2025, L2 order book snapshots, market metrics, across more than a million markets, with a genuinely API-first design: REST endpoints, a Python SDK, S3 bulk exports for anyone who wants to pull everything at once rather than query incrementally.

Pricing is tiered by request volume with an enterprise option for bulk access, though exact numbers sit behind a separate pricing page rather than the homepage. If Polymarket alone is your whole scope, this is a more programmatic option than Lychee. If you need Kalshi too, it's not here.

CoinAPI: broad crypto coverage including options, no prediction markets

CoinAPI is the most general-purpose of the three crypto-side providers: spot, futures, options, and derivatives data from more than 350 exchanges, with options coverage on Deribit, Binance, OKX, Bybit and others, delivered with normalized Greeks and IV so you're not remapping every exchange's own quirks by hand.

It's also the cheapest entry point of the crypto-derivatives group by a wide margin: plans starting around $79 a month, plus usage-based and one-off purchase options for lighter needs. Broad coverage, low floor, still zero prediction-market data.

Where that leaves you

If your research or product sits entirely on one side, crypto derivatives or prediction markets, any of these five is a reasonable, mature option, and the table above should tell you which one fits your budget and access style. The gap only matters if your work actually spans both: comparing implied-probability pricing on Kalshi against implied volatility on Deribit, building a strategy that touches Polymarket and Binance options in the same pipeline, or just not wanting to stitch two vendors' schemas together by hand.

Convex Lake exists specifically for that overlap. One API, one schema, covering Kalshi, Polymarket, Predict.fun, and Limitless on the prediction-market side, plus Deribit and Binance options on the crypto-derivatives side, batch and real-time. Not a replacement for Tardis's tick-level depth or Amberdata's institutional tooling if that's specifically what you need. But if you're currently paying for one crypto-derivatives provider and one prediction-market provider just to cover both halves of your own research, that's the exact redundancy this removes.
