Coinmate portfolio tracker: connect the API read-only, beside your stocks

Coinmate, the Czech exchange, is supported by few trackers — and most of the tools that name it are crypto tax calculators that do not hold shares. Fortunest connects Coinmate directly with a read-only API key and puts the coins in the same portfolio as your broker accounts, so it is our pick if Coinmate is one account among several. If all you need is a crypto tax report, Coinpanda and CoinLedger both connect Coinmate by API, and CoinTracking reads its CSV.

The short answer

• Coinmate's key comes in three parts. A Client ID, a public key and a private key, made under Account → API. Give it read permissions only — never trading, never withdrawal.
• Our pick for Coinmate beside stocks: Fortunest — a direct read-only connection that brings trades in CZK, EUR or BTC, settled deposits and withdrawals, and today's balances, in one portfolio with your broker accounts. It needs a free Fortunest account; there is no Coinmate CSV route. Pro is €69 a year.
• For a crypto tax report: Coinpanda or CoinLedger — both describe a read-only Coinmate API connection or a CSV upload. Coinpanda's free plan imports and tracks, and you pay to download the report.
• CSV only: CoinTracking — its Coinmate page has you export "CSV all" and upload it; no Coinmate API import is described.
• Czech tax tool: Taxomat — lists Coinmate among its crypto platforms and calculates crypto income including the time test, but does not say how Coinmate data gets in.

How to connect Coinmate

These are the steps the connect form in the app shows, and the requirements listed for Coinmate in every supported platform.

1. Create a key on coinmate.io Open Account → API and create an API key. Tick only the read permissions — Account balance and Transaction history — and leave every trading and withdrawal permission off. (Some other trackers' guides call the read box Account Info; the rule is the same whatever your screen calls it.)
2. Restrict it, if the form allows If Coinmate's key form offers an IP restriction, limit the key to the IP address Fortunest shows you, so a leaked key is useless anywhere else.
3. Paste the three values into Fortunest Signed in to the app, open ⚙ Settings → Data → Connect an account, pick Coinmate and paste the Client ID, public key and private key. The balance and the trade history are both tested before anything is kept, and nothing is stored unless it works.

The first sync walks your trade history and your deposits and withdrawals from the beginning; later ones are incremental and run in the background. The key is encrypted at rest, never sent to your browser and never logged, and the connected row shows only the public half. The app has no code that places an order or moves money.

What comes in, and what it becomes

Coinmate's trade history is broker-shaped: each row carries the amount, the price and a fee charged in the quote currency, so a buy for crowns is one trade that costs exactly the crowns that left your account, fee included. Pairs quoted in CZK or EUR come in priced; a pair quoted in BTC moves no cash, so the trade is valued through the bitcoin it was swapped against. Deposits and withdrawals of crowns and euros become cash movements, those of coins change the coin balance — and only settled ones count, so a pending withdrawal waits until it completes. Today's balances come in too: CZK and EUR as cash, coins as holdings.

Then it is one portfolio with the rest of what you own: Patria Finance in Excel, a Czech-locale DEGIRO file, an XTB export, a Trading 212 or Interactive Brokers connection — every supported platform — in one display currency converted at each day's rate, with TWR and IRR across the lot, transfers between your own accounts matched rather than double-counted, and the assistant answering about the actual holdings.

Czech tax and the time test

Most Coinmate clients are Czech or Slovak, and for Czech tax the question is usually which coins have passed the three-year time test. Fortunest's Taxes tab (Pro) pairs every sale with the lots it consumed and, on its Czech default rulebook, includes crypto in the time test for sales from 15 February 2025, with the 100,000 CZK annual small-sale limit counted for crypto separately from securities. It is orientation, not a filing. For the rules themselves in Czech, read our Czech guide to taxes and the time test.

The tools that read a Coinmate account

Each cell is what the vendor's own pages say, checked in October 2026. Not described means the page we read does not mention it. A green ✓ marks whichever product leads a row on that row's own terms.

Cells were checked against the sources below in October 2026. Prices are list prices before promotions and, for Fortunest, before VAT. "Not described" and "not checked" are statements about those pages on that date, not about the product.

The verdicts

Koinly, and the trackers that do not name Coinmate

Koinly's Coinmate guide, as returned by search, describes both an API key and a CSV upload; its site refused our direct fetch, so it is not in the table. CoinStats, which connects Kraken, has no Coinmate connection page. If you hold Kraken or Binance too, the Kraken guide and the stocks-and-crypto guide compare the trackers for those.

How we compared

We searched for every tool that names Coinmate and read each one's own Coinmate, home and pricing pages rather than a review site. Where a page says nothing about a row, the cell says so. We build Fortunest, so we are not neutral: the table is meant to be checkable rather than impartial, and every product's limits are in its verdict, ours included.
