Full Level-2 order book, trades and derivatives topics for Binance USDT-M and Binance Spot over a plain WebSocket in JSON or SBE — captured at the venue in Tokyo and delivered at our London endpoint over a dedicated line. You buy whole UTC calendar days and connect with one API key.
Latency is one-way, including Binance exchange latency — measured against the Binance transaction timestamp "T", not the event timestamp "E".
Every topic below is the same stream our own systems consume — the historical files in the shop are recordings of it, so a backtest maps 1:1 onto production.
| Topic | What you receive | Binance USDT-M port 14004 | Binance Spot port 14003 |
|---|---|---|---|
| Order book | Full-depth snapshot on subscribe, then changed levels only; every event chained by prevEventId/eventId, matching-engine timestamps. | ✓ | ✓ |
| Top of book | Best bid and ask as its own stream; optional coalescing for slow consumers. | ✓ | ✓ |
| Trades | Every public trade: aggressor side, price, quantity, trade id, matching-engine timestamp. | ✓ | ✓ |
| Mark price | The venue's mark price as it is republished. | ✓ | — |
| Index price | The underlying index price. | ✓ | — |
| Funding rate | Current rate, next settlement time and the venue's predicted next rate. | ✓ | — |
| Liquidations · opt-in | Liquidation orders as the venue publishes them: side, price, quantity, exchange timestamp — off by default, opt in per subscribe. | ✓ | — |
Mark price, Index price, Funding rate, Liquidations do not exist on Binance Spot — the venue never publishes them there.
One day or thirty — paid days start at the next 00:00 UTC and the rest of the purchase day is included free, so access begins the moment the order clears. Extend any time from your account, invoice on checkout.
A market day unlocks every instrument of that market; an instrument day unlocks exactly the instruments you pick. €39.20 per instrument-day or €79.20 per market-day (public-beta price, 20 % off the list price of €49 / €99 for every day bought during the beta).
The key is created with your first purchase and shown in your account together with the endpoints. It authenticates the feed and the master-data export, and you can rotate it whenever you want.
WebSocket in JSON or SBE, the same protocol and subscribe flow as our documented market-data API: Binance USDT-M (port 14004) and Binance Spot (port 14003). Instrument master data is a free export from the shop.

Public beta: every day bought while the beta runs is 20 % below the list price (€49 / €99 per day). The feed and the protocol are our production platform; the self-serve path is new — tell us what you need.
Captured at the venue in Tokyo and delivered at our London endpoint over a dedicated line — that low-latency path is what the per-day price pays for. London is the first self-serve location; more will follow, and enterprise subscriptions already cover further locations and venues. See the enterprise tiers for order entry, T+1 history and monthly API swaps.
