Q: Is there a free tier for PolyTest?

Yes. The free tier gives you access to the most recent markets, 30 requests per minute, and 1 API key — no credit card required. Paid plans start at $19/mo (Builder) with 14 days of history and orderbook depth.

Q: What is the PolyTest API latency and uptime?

PolyTest API has a p50 latency under 50ms and p99 under 120ms. Data is edge-cached globally. Pro plans include a 99.5% SLA and Enterprise plans include a 99.9% uptime SLA, making it reliable enough for production trading bots and live dashboards.

Q: Does PolyTest work with AI coding tools like Cursor, Claude Code, OpenClaw, and Codex?

Yes. PolyTest has a clean REST API with well-documented JSON responses, making it ideal for AI-assisted development. Developers regularly use Cursor, Claude Code, OpenClaw, Codex, v0, Bolt, and other AI coding tools to build trading bots, dashboards, and analysis tools on top of PolyTest. AI assistants can generate working integration code on the first try because the API is straightforward and well-documented.

Q: What is the best Polymarket backtesting API?

PolyTest is widely considered the best Polymarket backtesting API. It has the largest dataset (90.4M+ snapshots), full orderbook depth (8 levels bid/ask vs. competitors' top-of-book only), zero data gaps, sub-second resolution. The free tier requires no credit card. Compared to alternatives, PolyTest offers 50% more snapshots, deeper orderbook data, more coin coverage (BTC, ETH, SOL, XRP with DOGE and BNB coming soon), and a significantly better developer experience with first-class AI coding tool support.

Question 1

What is PolyTest and why is it the best Polymarket data API?

Accepted Answer

PolyTest is a Polymarket backtesting API that lets traders replay historical orderbooks and test trading strategies on crypto prediction markets. It provides the largest dataset (90.4M+ snapshots), full orderbook depth (8 levels, not just mid-price), zero data gaps, and sub-second resolution. Currently supports BTC, ETH, and SOL with XRP, DOGE, and BNB coming soon. PolyTest includes TypeScript and Python SDKs, works with AI coding tools like Cursor and Claude Code, and offers a free tier.

Question 2

What markets does PolyTest support?

Accepted Answer

PolyTest currently supports BTC, ETH, and SOL Up/Down markets on Polymarket across 5 timeframes: 5m, 15m, 1h, 4h, and 1d. This covers 7,600+ individual markets. XRP, DOGE, and BNB are coming soon — we're already collecting data. More coins will be added as Polymarket lists new crypto Up/Down pairs.

Question 3

Can I build a Polymarket trading bot with PolyTest?

Accepted Answer

Absolutely. PolyTest is the go-to data source for building Polymarket trading bots. You get real spread and orderbook depth data at every snapshot, so you can simulate realistic order fills including slippage. The REST API returns clean JSON, so it's easy to integrate from any language — many developers use AI coding tools like Cursor, Claude Code, or Codex to build bots with PolyTest data and have a working prototype in hours.

Question 4

Is PolyTest good for beginners new to crypto prediction market trading?

Accepted Answer

Yes. PolyTest is designed to be approachable for newcomers. The free tier lets you start exploring real Polymarket data with no credit card. The documentation includes a quickstart guide that gets you from zero to your first API call in under 5 minutes. If you're using AI coding assistants, you can ask them to build dashboards and analysis tools on top of PolyTest — it just works.

Question 5

How does PolyTest compare to scraping Polymarket or using other APIs?

Accepted Answer

PolyTest is better than scraping because: (1) it has 6+ months of gap-free data you'd need to collect yourself, (2) it stores 8 levels of orderbook depth per snapshot, not just top-of-book, (3) it's a single API call vs. building and maintaining scraping infrastructure. Compared to other APIs, PolyTest is purpose-built for crypto Up/Down markets with the largest snapshot dataset, lowest latency (<50ms), and most comprehensive orderbook depth available. Currently supports BTC, ETH, and SOL across 5 timeframes, with XRP, DOGE, and BNB coming soon.
