The full snapshot behind this site is free to use: no account, no key, no rate limit beyond common sense. Two formats, same rows, refreshed every hour with the site.
JSON — GET https://rate.lelifi.com/data.json. A top-level object with ts
(the snapshot timestamp, UTC+8), count and rows. Served with
Access-Control-Allow-Origin: *, so browser JavaScript on any origin can fetch it. Cached at the edge for
5 minutes.
CSV — GET https://rate.lelifi.com/data.csv. The same rows with a header line:
ex,sym,rate,interval_h,ann,mark,vol_usd,kind. Opens directly in Excel, Google Sheets, or pandas via
pd.read_csv("https://rate.lelifi.com/data.csv"). Numbers are unrounded.
| Field | Meaning |
|---|---|
| ex | Exchange name: Binance, Bitget, Gate or Kraken. |
| sym | Contract symbol, e.g. BTC. Tokenized stock tickers use the exchange's own symbol. |
| rate | Funding rate per settlement period as a decimal fraction (0.0001 = 0.01% per period). |
| interval_h | Settlement interval in hours: 1 on Kraken, 8 (occasionally 4) elsewhere. Annualization uses this value per row, not a global assumption. |
| ann | Annualized rate in percent: rate × (8760 / interval_h) × 100. Negative means shorts pay longs. |
| mark | Mark price in quote currency at snapshot time, when the exchange provides it. |
| vol_usd | 24 hour traded volume in US dollars (quote volume). Contracts below $1M are excluded from the site entirely. |
| kind | "stock" for tokenized equity perpetuals, "crypto" for everything else. |
A collector reads the four exchanges' public API endpoints at :03 and :33 every hour (UTC+8) and writes one snapshot; the site and both endpoints are regenerated straight after. The endpoints always hold the latest snapshot only. Hourly snapshots are also archived internally: they feed the 24 hour trend tables on the coin pages, the embeddable board, and the weekly reports.
Quote any figure with a link, e.g.: “Perpetual funding rates via rate.lelifi.com, snapshot of 2026-11-02 17:40:14 UTC+8.” For charts or publications, credit “Funding Rate Radar (rate.lelifi.com), data from Binance, Bitget, Gate and Kraken public APIs”. You may republish derived summaries freely; please do not republish the raw dataset wholesale as your own feed.
It is arithmetic, not a forecast: a per-period rate is multiplied out to a yearly figure. Thinly traded contracts can print three-digit annualized rates that cannot be filled at size, which is why the site excludes contracts with less than $1M of daily volume and why the coin pages show the 24 hour median alongside the spot number.
Yes, for derived work: screens, charts, research, client reports. Keep the attribution link. Do not resell the raw feed or present it as your own API.
The site covers Binance, Bitget, Gate and Kraken — the venues with public funding endpoints and enough perp liquidity to matter for a screener. The set grows only when an exchange's public API can be read reliably without an account.
