Coinbase portfolio tracker: the read-only API key, the Transaction history CSV, and your stocks

Coinbase can reach a tracker through a read-only CDP API key that keeps the account current, or through the retail Transaction history CSV you download yourself. The file is where trackers go wrong: a retail buy's total includes Coinbase's spread, a Convert names what you received only in a free-text note, and some downloads open with a title block that makes the file unreadable. Fortunest handles all three, takes the key and the file together with a cutover date so nothing is counted twice, and puts Coinbase in the same portfolio as your shares. It is our pick for that; CoinTracking is the specialist if crypto tax is all you need.

The short answer

• Two routes. The API key reads your balances and trade fills and keeps itself up to date; the CSV is a record you re-export by hand, and it is where sends, receives, Converts and rewards are spelled out row by row.
• Our pick: Fortunest — your own read-only CDP key (it needs a free Fortunest account) or the Transaction history CSV (no account at all), imported at the spot price rather than total ÷ quantity, in one portfolio with your broker accounts. Free plan: three accounts, fifty assets; Pro is €69 a year.
• Crypto tax: CoinTracking — Coinbase by API key, CSV or its legacy imports, spot, staking and Earn, worked into a tax report. Crypto only.
• Crypto and DeFi wallets: CoinStats — Coinbase listed with OAuth, API sync and CSV, read-only. Its pages describe crypto, DeFi and NFTs, not shares.
• Shares too: Delta, Kubera and getquin — a phone app, a whole-net-worth tracker and a broker-first app, each with what we could and could not read on its own pages below.

How to connect Coinbase, or export its history

The key steps are the ones the connect form in the app walks you through; the file details are in the Coinbase section of the docs.

1. Create a read-only CDP key On portal.cdp.coinbase.com open API keys → Create API key. Give it the View permission only — no trade, no transfer. Coinbase's own guide says to choose ECDSA as the signature algorithm; Fortunest reads that PEM block, and an Ed25519 secret too.
2. Allowlist one IP Add the address the Fortunest form shows you to the key's IP allowlist, so a leaked key is useless anywhere else. Coinbase calls the allowlist recommended rather than required; take the recommendation.
3. Paste the key name and the private key In the app, signed in, open ⚙ Settings → Data → Connect an account, pick Coinbase and paste the key name (organizations/…/apiKeys/…) and the private key — the whole block, -----BEGIN and -----END lines included. Coinbase no longer downloads the key file automatically, so copy both from the dialog or press its download button before you close it. The key is checked live and nothing is stored unless it works.
4. Or export the history instead Coinbase's help centre puts it under Statements in your account settings: generate a custom statement — every asset, every transaction type, the whole period — as CSV. Statements reach back to when the account was opened.
5. Strip the title block, then drop it in If the file opens with a Transactions title block above the column headings, delete those lines first, or it is refused as unrecognised. Then drag it onto the Portfolio value tile, or onto the Data sources card under ⚙ Settings → Data. No Fortunest account is needed for a file.

Using both is safe. A connection made while a Coinbase file is already loaded starts on files first: the file covers its period and the connection takes over the day after the file's newest transaction, so the same fills are never counted twice. You can switch it to files only or connection only later — the latter turns the overlapping files off rather than deleting them.

What a tracker has to get right with Coinbase

Four details decide whether the numbers come out right, and they are worth testing in whatever you choose.

• The spread. On a retail buy the Total includes fees and Coinbase's spread, so total ÷ quantity is not the price you were quoted. Fortunest imports the trade at the spot price the file states and books the total as the cash that moved, so the spread is a cost you can see rather than a price that never existed.
• Convert rows. The file names only the coin you gave up in its columns; the one you received sits in the note — “Converted 0.5 ETH to 1 200 USDC”. Both legs are read out of that note. It is prose, and only read in English: a localised export still imports the sold leg, and the received one is counted and reported rather than guessed.
• The currency. Amounts are printed with a glyph, and a $ names half a dozen currencies. The currency comes from the file's own Price Currency column; where the glyph disagrees, the column wins and the disagreement is kept for audit.
• Transfers and rewards. Send and Receive are transfers, not trades; staking, rewards, interest, Learning and Earn payouts are income at zero cost, so all of their value counts as profit. Older exports spell four of the columns differently and read the same way.

The key route works differently. It reads your balances and the trade fills Coinbase's Advanced Trade API reports: a fill quoted in euros, dollars or pounds is the cash movement itself, a fill quoted in USDC or another dollar stablecoin is valued 1:1 in US dollars, and a crypto-for-crypto fill is valued at the counter-coin's price that day. Sends, receives and rewards are not part of what the key fetches; the balances still come out exact, because the history is forced to end on what the exchange says you hold, and a coin with no purchase in the record is dated as late as the evidence allows. That is why the file and the key together are the fullest picture.

Coinbase and your stocks, as one portfolio

A Coinbase app already shows your coins. What it cannot show is the broker account beside them, and that is what Fortunest is for — the stocks-and-crypto guide covers it across every source. The Coinbase connection or file lands in the same holdings table as the CSV exports of 29 platforms, 22 brokers through SnapTrade, and direct connections for Trading 212 and Interactive Brokers. Every day is converted at that day's rate into one display currency, and the Portfolio tab reports total P/L, annualized TWR and money-weighted IRR over the whole lot against benchmarks fed your own deposits.

Coins sent from Coinbase to your own wallet are matched as transfers rather than booked as a sale — a Trezor Suite export's on-chain moves are netted against your exchange withdrawals and deposits. The Taxes tab (Pro) pairs every sale with the lots it consumed and applies a holding-period test that includes crypto — one configurable rulebook with Czech defaults, no per-country presets. And the assistant reads the same combined portfolio: ask what share of your return came from crypto, or tell it to sync Coinbase and it pulls fresh data the way the Sync button does.

The trackers people use for Coinbase

Each cell is what the vendor's own pages say, in the vendor's terms, on the date in the footnote. Not described means the page does not mention it; not checked means we did not verify it. A green ✓ marks whichever product leads a row on its own terms.

Cells were checked against the sources below on 8 October 2026. Delta's site and help centre, getquin's help centre and Coinbase's statements help page refused our direct fetch that day, so those details come from their own pages as returned by search — treat them as one step further from the source than the rest; getquin's pricing page was read directly. CoinStats' pricing page gives different portfolio and transaction limits in different sections, so we quote none of them. Prices are list prices before promotions and, for Fortunest, before VAT. Footnote 2 is Coinbase's own documentation, used in the steps above.

The verdicts

How we compared

We read each vendor's own connection, help and pricing pages rather than review sites, and say so where a site refused us. For Fortunest we read the Coinbase connector's and importer's code as well as our docs, so the limits in its verdict are the ones the code has. 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.
