Verifiable crypto market infrastructure

Crypto market data, with the evidence attached.

Ask every venue the same question in DQL, see one instrument on every venue side by side, get told when a condition becomes true, and place orders through a Runner on your own infrastructure — without hiding the source, age or absence of the underlying data.

Explore live data

Live market proof

One instrument across the venues that quote it, with three clocks per row.

Ticker, open interest and depth arrive by different calls at different rates, so the table shows an age for each group — never one age per row. Freshness is judged per call against that call's expected cadence.

DQL · DEBYKO Query Language In development

Stop coding the same market checks differently for every exchange.

Write the condition once. DQL handles the rest — across every venue.

What you mean

BTC on Kraken and Hyperliquid more than 35 bps apart, both books holding $100,000 within 25 bps, every price under half a second old, and hourly funding more than 1 bps apart.

You define the market condition. We deal with the exchanges.

One query, every venueNo Binance branch. No Hyperliquid branch. No Bybit branch. One condition against every venue that lists the instrument.

Stale data can’t trigger your botage(funding) < 2s is part of the condition. A venue that stopped answering does not silently keep yesterday’s value alive.

Backtest the same questionAdd as of 2026-09-22T08:00:00Z. The condition is evaluated against only what DEBYKO had actually received by that instant.

Send the result to your botJSON through the API. A webhook on match through Agent. Or let Runner place the order with your own keys — DEBYKO never sees them.

Why did my bot do that at 14:03:07? Ask the API. It answers with what your bot could have known then.

Your market-data layer becomes an HTTP client and a where clause. Every value with its venue, receive time, age and unit; the venue's raw fields next to ours; nothing invented when a venue goes quiet.

Principles

Nothing is shown as more than it is.

Six rules the product is held to. The page above is held to the same rules.

01Every value keeps its source venue and instrument.
02Every value shows when it was received, and its age.
03Missing data stays missing. It is never turned into zero.
04Stale data is never presented as live.
05Derived values say what they were computed from.
06Coverage limits stay visible.

01 / Market data Free · Live Subscription · Pre-launch

Studio

One instrument on every venue that quotes it, side by side.

Live values, history with its gaps left in, and what each venue showed at any past moment. When you act, the order goes to your own Runner and is placed with your keys.

A missing observation is empty, not zero. The age and origin of every value stay visible.

02 / Data for your code v1 · Live v2 · In development

API

The same data as Studio, for your code.

v1 serves facts: coverage, snapshots, order books, candles, trades and a live stream. v2 adds DQL, one query language for screening and point-in-time questions across venues.

One key will cover Studio, API and Agent. Until keys ship, v1 is open.

Three clocks in one row: receivedAt, openInterestAt, depthAt. null means the venue does not provide the field — never 0.

03 / Alerts Planned

Agent

Write what to watch. Hear when it becomes true.

Write a condition in DQL. Agent evaluates it on your schedule and tells you by Telegram or webhook when it becomes true, with the values and their sources attached.

It receives your Runner's execution reports and publishes how often each rule fired — never whether it was right.

04 / Execution In development

Runner

Your orders, placed with your keys, on your infrastructure.

Runner runs on your infrastructure, not ours. It takes a webhook from Agent or Studio, places the order on the exchange with your own API keys and reports the execution back.

DEBYKO never sees your keys or your funds.

05 / Agent board Closed beta

Arena

A public board of agents, built from their execution reports.

Expectancy, drawdown, share of losing trades, venues traded. Every row says whether its figures are self-reported or verified. Opt-in, under a pseudonym.

Today it shows the first two agents, self-reported. Reports from other Runners come with Runner.

For CASPs, brokers and execution teams

Reconstruct what other venues showed when an order was executed.

For a given execution time and instrument, Debyko assembles what it had observed on alternative venues: bid and ask, spread, depth bands, and the age of each observation at that moment — with coverage limits stated in the report.

Method notes
Observations are the last received before the execution time on each venue; their age at that moment is printed, not hidden.

Coverage and gaps
Venues not collected at the time are listed as not covered. Gaps in collection are stated per venue and per call.

Derived values
Spread = (ask − bid) / mid × 10,000 bps. Depth bands measured against the stated reference price.

Methodology

The method is part of the product.

Two timestamps exist. Age is the difference to now.

Venue timeif supplied · 17:15:52.299

→

Receivedalways · 17:15:52.301

→

Agenow − received · 0.2 s

There is no stored "written" or "available" time, so none is shown.

Ticker, open interest and depth arrive by separate calls; each keeps its own received time and age.
A gap inside collection and a period before collection began are named differently. Neither is a zero.
BEST and WORST rank only values that are present, live and from an order book.

Read the methodology Inspect data coverage

Status and quality

Data quality is public system state.

Per venue and per collector, with ages. There is no single "all systems operational" badge: a degraded depth feed on one venue is shown as exactly that.
