best_opportunities | Ranked 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_overview | Funding 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_breakdown | Full 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 (Authorization: Bearer |
funding_rates | Current 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_rates | Margin 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_floating | Pendle 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_cost | Taker fee + order-book slippage to buy or sell a given USD size of one coin on every exchange (perps and spot), cheapest first. |
basis_trades | Spot 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_routes | Buy 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% / 1%, arrival estima |
pair_history | Funding 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_structure | Annualised basis of every delivery future of one coin on every exchange we cover, next to perp funding. |
venue_execution_cost | Taker fee plus order-book slippage to enter $10k / $100k / $1M long and short on one exchange's biggest markets, in basis points. |
service_status | Whether AfterFees data is live right now, which exchange feeds are down, and availability over 1 / 7 / 30 / 90 days. |
order_checklist | The 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_scenarios | Net 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_calculator | Net, 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_calculator | Locked 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_calculator | Buy 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_market | Detail 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_basis | Lock funding on Boros against a delivery future of the same maturity: implied APR vs basis APR, net after fees and slippage at your size. |
exchanges | Every exchange AfterFees reads: kind, fully calculated or watch-only, status, markets, taker / maker fee, open interest, 24 h volume. |
exchange_overview | One exchange: fees and their source, funding intervals, open interest, volume, highest and lowest funding and its best after-fee pairs. |
coins | Coins with a perp on two or more exchanges: exchange count, open interest, highest and lowest funding APR and the best after-fee pair. |
track_record | How AfterFees' daily top picks actually did: predicted net vs net realised from settled funding over the hold, hit rate, mean error, latest picks. |
dex_scan | Tokens 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.
