best_opportunitiesRanked funding-rate arbitrage pairs (long one market, short another) with the net result after taker fees and order-book slippage at your size, max size, breakeven, settled 7-day replay, tier (actionable / watch) and reasons.
coin_overviewFunding rate of one coin on every exchange (rate, interval, APR, predicted, OI, volume, settled 7-day sum) plus its best pairs, net after fees and slippage at your size.
pair_breakdownFull calculation of one pair: funding per leg and settlement count, taker fees, order-book VWAP and slippage per trade, carry, net, net if rates halve, breakeven, capacity, settled 7/30-day replay. pair_key comes from best_opportunities or coin_overview. Needs a Pro API token (Au
funding_ratesCurrent perpetual funding rates (gross, before costs). With base: that coin on every exchange, highest first. Without: the top N markets by absolute APR (OI filter applies).
borrow_ratesMargin borrow rates per coin and exchange (VIP0, current and 24 h / 7 d averages, limits, inventory) with the most negative perp funding: the two halves of a reverse spot-perp carry.
fixed_vs_floatingPendle Boros markets: the fixed funding rate you can lock (net of Boros fees and fill at your size) against the term-matched floating benchmark, advantage, win rate, capacity. side=short locks an income, side=long locks a cost.
execution_costTaker fee + order-book slippage to buy or sell a given USD size of one coin on every exchange (perps and spot), cheapest first.
basis_tradesSpot or perp against a dated future held to delivery, on one exchange or across two (perp on one, future on another), and two same-day futures on different exchanges: net to expiry after fees and slippage at your size, net APR, basis APR, max size, tier and reasons.
transfer_routesBuy a coin on one exchange, withdraw it on a network both exchanges share (same chain and contract, never matched by ticker), sell on another: real-transfer net after taker fees, order-book slippage and the withdrawal fee at your size, pre-funded net, capacity at net >= 0 / 0.3%
pair_historyFunding actually settled on both legs over 7 / 30 / 90 / 180 / 365 days, applied to today's orientation at your size: net after the four trading costs, max drawdown, negative days, daily sign flips, how far back each exchange's history reaches. Ranges beyond 7 days need Pro.
term_structureAnnualised basis of every delivery future of one coin on every exchange we cover, next to perp funding.
venue_execution_costTaker fee plus order-book slippage to enter $10k / $100k / $1M long and short on one exchange's biggest markets, in basis points.
service_statusWhether AfterFees data is live right now, which exchange feeds are down, and availability over 1 / 7 / 30 / 90 days.
order_checklistThe two orders to place by hand for one pair: action, exchange, symbol, quantity in the exchange's own unit (contracts where one contract is not one coin), notional, assumed leverage and a link to each contract's trading page (no referral parameters). AfterFees never trades.
holding_scenariosNet after fees and slippage of one live pair held 8 h, 1 d, 3 d, 7 d and 30 d, optionally with your own assumed funding rate per leg (percent per funding period, keyed by instrument_id).
manual_calculatorNet, net APR, breakeven and funding-halved case for two legs you describe (no live data): each leg {side: long|short, rate_pct per period, interval_hours, taker_bps, first_in_hours?}.
boros_lock_calculatorLocked net (income) or cost APR on Pendle Boros at an implied APR you give, after the taker and settlement fees and the entry cost, its advantage over a floating APR you expect and the break-even floating rate. Percent inputs.
transfer_calculatorBuy on exchange A, withdraw, sell on exchange B at prices you give: real-transfer and prefunded net, break-even premium. Fees in percent, withdrawal fee in coins.
boros_marketDetail of one Boros market (id from fixed_vs_floating): fixed rate at your size net of fees, floating benchmarks, advantage, win rate, capacity, reasons.
boros_futures_basisLock funding on Boros against a delivery future of the same maturity: implied APR vs basis APR, net after fees and slippage at your size.
exchangesEvery exchange AfterFees reads: kind, fully calculated or watch-only, status, markets, taker / maker fee, open interest, 24 h volume.
exchange_overviewOne exchange: fees and their source, funding intervals, open interest, volume, highest and lowest funding and its best after-fee pairs.
coinsCoins with a perp on two or more exchanges: exchange count, open interest, highest and lowest funding APR and the best after-fee pair.
track_recordHow AfterFees' daily top picks actually did: predicted net vs net realised from settled funding over the hold, hit rate, mean error, latest picks.
dex_scanTokens our exchanges list with a verified contract on Ethereum, BNB Chain, Base, Arbitrum or Solana whose DEX price is more than 1% away: net at $1k / $5k / $10k after aggregator price impact, swap gas, the token transfer gas and the exchange's withdrawal fee, status and reasons.
spread_chartCandles of (A − B) / B between any two instruments (book mids where stored, else marks). Free: 1 h candles and longer over up to 7 days; Pro: 1 m and up, up to 365 days.
my_positionsYour positions across the read-only exchange keys connected to your AfterFees account, grouped into hedges: delta drift, distance to liquidation, funding received, issues. Needs a Pro account token; AfterFees only accepts read-only keys. Needs a Pro API token (Authorization: Bear
spread_convergenceThe same coin priced differently on two exchanges' perpetuals: long the cheaper, short the dearer, close when the gap returns to its 7-day median. Net at your size after four taker fees, slippage on live order books and stablecoin conversion; how often the gap came back over 7 da

Crypto funding-rate arbitrage for AI assistants, with every number net of fees and order-book slippage.
AfterFees prices ~75,000 long/short pairs across 50 exchanges (CEX, perp DEXs, Hyperliquid HIP-3) and tells you what a trade would actually earn at your size: funding minus taker fees on all four fills, slippage walked on the live order books, borrow interest, stablecoin conversion and holding period. Most screeners show the gross rate spread; once costs and real order-book depth are counted, often only a handful of the tens of thousands of pairs can be opened at $10,000 per side. This server gives your assistant the same numbers as afterfees.xyz.
