A CoinGlass alternative, compared row by row.

1. Funding and open interest: the overlap

Both products serve code that compares perpetuals across exchanges.

CoinGlass documents exchange-level funding rates, funding history, open interest, historical open-interest series and derived indicators. Its funding exchange list returns the exchange, the funding interval, the current rate and the next funding time [3]. The open-interest exchange list is cached for 10 seconds; the funding list for 20 [3][4].

DEBYKO returns funding and open interest per venue, as published, with the interval the venue uses and the same rate over eight hours for comparison. DQL lets you ask across venues in one query instead of fetching every instrument and filtering in your code [9].

count(venues where funding < 0) >= 2

Instruments where at least two venues publish negative funding, evaluated with the query's freshness rules.

Neither product's funding numbers are a trade. Settlement schedules, contract specs, fees, liquidity and execution still decide.

2. A market value needs a clock

A price, a funding rate or an open-interest figure can be a valid number and no longer current.

CoinGlass publishes update intervals per endpoint, for example 20 seconds for the funding exchange list and 10 seconds for the open-interest exchange list [3][4]. Those describe the API's cache, not when the exchange produced the value.

DEBYKO puts the timing into the value itself.

{
  "status": "present",
  "venue_ts": "2026-10-09T18:51:04.113Z",
  "received_at": "2026-10-09T18:51:04.152Z",
  "age_ms": 82,
  "valid_until": "2026-10-09T19:01:04.113Z",
  "horizon_source": "connection",
  "values": {
    "mark": 82570.41442652237,
    "index": 82563.32,
    "basis": 0.000085927098
  }
}

The venue's own timestamp, the time DEBYKO received it, the age counted from the venue's time, and until when the value counts as current. DEBYKO also records where the horizon comes from: measured, documented, assumed, venue_declared (the venue says when the next value comes) or connection.

This is not a claim that DEBYKO is faster. It is a different measurement: how old a value is by the venue's clock, not how often an API refreshes.

3. When the feed stops

When a value is past its horizon, DEBYKO does not keep showing the old number as current.

This answer did not include that example. Nothing is shown in its place.

The status and the reason stay; the number leaves the value field. With allow_stale the old number comes back separately under withheld, never as a current value.

Four states that are not the same thing: a value you can use; a value that exists but is stale; a value the venue did not publish; a value whose freshness cannot be established. A stale value shown as current distorts a cross-venue comparison; a missing value shown as zero distorts it the other way.

CoinGlass documents update intervals and response shapes. The reviewed documentation does not describe a per-value validity or withheld-value contract. That is a documentation boundary, not a claim that CoinGlass hides or invents anything.

4. History: a series versus a state

CoinGlass sells history by interval and plan. On the pricing page as of 2026-10-09: 1-minute data 6 days on Standard and 12 on Professional, nothing shorter than 4-hour data on Hobbyist, 1-day data all-time on every plan [1].

DEBYKO answers point-in-time questions: what was known about this instrument at this instant, and was it still valid then. History has three modes [9]. at is the state at named instants. interval is a range sampled at a chosen step. raw is the recorded rows as they arrived. The answer carries the status of that moment, including an expired horizon or a collector outage.

Two honest limits. DEBYKO's history starts in September 2026, when collection began; CoinGlass goes back years for daily data. And point-in-time state is not tick-level reconstruction: check DEBYKO's retention and sampling per dataset before using it for microstructure research.

For long daily lookbacks, CoinGlass. For the state of a value at a moment, DEBYKO.

5. Indicators versus queries

CoinGlass ships indicators: long/short ratios, liquidation analytics, funding aggregates, options data [2]. Less to build.

DEBYKO ships a query language. You write the condition over the data and inspect the values, their timestamps and their statuses. More control, and no library of prepared metrics. If the metric you need exists in CoinGlass, their endpoint is the shortest route. If your question combines venue-specific conditions with the state of the underlying values, start with DQL [9].
