PolyHistorical vs PolyOrderbooks

• PolyHistorical — BTC Up/Down at 5m, 15m, 1h, 4h, 24h; ETH and SOL at 5m, 15m, 1h. 13,000+ resolved markets; archive kept after resolution.
• PolyHistorical Pro adds historical Binance BTC/USDT spot and USD-M futures depth for cross-market analysis.
• PolyOrderbooks — the full crypto Up/Down archive (5m, 15m, 4h anchors plus thresholds and event-linked) and 700k+ sports markets across 226 series, with prices and metrics in the same archive.
• PolyOrderbooks keeps resolved markets queryable as well; coverage stretches back years before either service's newer competitors began recording.

PolyHistorical documents 300ms L2 snapshots and sub-50ms responses on its public site, oriented to execution-aware replay of BTC/ETH/SOL markets. It is a strong spec for that lane.

PolyOrderbooks captures and serves at 250ms on every plan, including free Starter; measured server-side history reads (~1ms), with end-to-end <50ms on well-connected networks, and does not rely on a competitor's rolling window: paid access reaches 30–120 days of history for crypto and 30 days for sports, with resolved markets remaining queryable.

Both are fine enough to see the settlement-minute moves a 1-minute grid hides. If you work BTC-only, PolyHistorical is competitive; if your research spans other assets, sports, or metrics in the same rows, PolyOrderbooks carries them.

• PolyHistorical Starter — free, no card; limited to recent BTC markets by count (last 50 five-minute and fifteen-minute, last 24 hourly and four-hour, last 5 twenty-four-hour), 60 req/min, 1,000 req/day.
• PolyHistorical Pro — $17/month; 31 days of covered BTC/ETH/SOL markets, Binance depth, Strategy Replay, 300 req/min.
• PolyHistorical AI — $29/month; Pro data plus ~100 AI strategy backtests.
• PolyHistorical Suite — $37/month; 60-day history plus the AI backtests.
• PolyOrderbooks Pro — $19/month at the time of writing; 250ms L2, prices, and metrics with a full multi-day window, resolved markets queryable (catalog 1.31M markets, 2.987B book snapshots).
• Both offer enterprise contact for the long archive; PolyOrderbooks also ships S3 delivery on enterprise.

If your strategy universe is BTC Up/Down only (with ETH and SOL secondary) and you want the narrowest, cheapest execution-aware depth feed with an integrated Strategy Replay, PolyHistorical's Pro tier is a credible, cheaper lane than broader platforms.

If you need the wider archive — altcoins, sports, metrics, thresholds — or a 12-month-plus history window for research that competes with published settlement studies, that is PolyOrderbooks' lane. The honest product advice: price alone is covered by the free official API; depth below 1 minute is a recorded-archive problem either way.

Take one concrete job: stress-test a BTC Up/Down strategy against the settlement minute. PolyHistorical&#39;s 300ms BTC depth with Binance spot and USD-M futures crossing is precisely built for this lane, and its $17 lane for BTC-only work is a strong value. The 250ms PolyOrderbooks grid serves the same BTC minute too, alongside ETH, SOL, and the rest of the crypto family in the same query.

Now widen to a research question that crosses assets: compare final-minute behavior across crypto and a sports event, or rerun a published settlement study that counts resolved contracts across an eighth-month window (298 in the BTC corpus alone). That is not a BTC-only lane; the wider archive covers it in one place, while the narrower product would need per-asset accounts.

Both products keep resolved markets queryable, so neither loses your study when the market settles. The real signature is the window: thousands of contracts over many months versus the last few weeks of paid browsing, and the free tier that reaches multi-year coverage only on the wider archive.

Choose PolyHistorical when the universe is BTC Up/Down first, ETH and SOL second, and the integrated Strategy Replay is your daily tool. Choose PolyOrderbooks when altcoins, sports, thresholds, or a years-spanning history window enter the question.

The honest tiebreaker is the free tier: start on the PolyOrderbooks Starter for one replay, narrate the settlement-minute behavior, and then check whether the narrow $17 product is actually your workflow. Most multi-asset work stays on the wider archive; the narrow lane is a real but smaller population.
