analyze_persona ~1,033
当用户描述自己的交易类型/身份（新手小额买入、定投囤币、活跃现货、合约波段、高频刷单、高净值机构、链上无 KYC 玩家）并想知道哪种交易所最适合自己、一年真实总花费多少时使用。Use when the user asks which exchange fits THEIR kind of trading, describes themselves as a beginner/HODLer/swing trader/scalper/institution/no-KYC trader, or wants an all-in annual cost for a trader scenario. Loads a research-anchored persona preset (casual_buyer, hodler_accumulator, active_spot_trader, swing_futures_trader, day_scalper, vip_institutional, dex_native) that bundles monthly volume, maker share, futures holding hours, market-order clip size, withdrawal and fiat on/off-ramp habits, then runs the FULL annual cost stack across every venue allowed in the country — trading fees + funding + spread crossing + on-chain withdrawals + direct fiat deposit/cash-out legs — and returns the ranked venues with cost-mix %, cheapest-venue leader for each cost component, a winner with concrete reasons and trade-offs, and tailored advice (VIP upgrade saving, token-discount hint, live funding/depth suggestions). Every preset parameter can be overridden. Requires persona id and country code.

analyze_token_discount ~555
当用户问持有某个交易所的平台币（BNB/GT/KCS/BGB/MX/HYPE）来抵扣手续费是否划算、多久能回本、能承受币价跌多少时使用。Use when the user asks whether holding an exchange's native token for fee discounts is worth it, how long until the discount pays back the locked capital, or how far the token price can drop before the saving is wiped out. Computes the annual trading fee WITHOUT the native token (zero-balance tier, no fee-deduction toggle) vs. WITH the token (GT/KCS/BNB holdings can lift the VIP tier; BNB/MX/BGB/KCS give a flat fee-deduction; Gate GT and MEXC MX and Hyperliquid HYPE have holding-tier discount ladders; Gate futures maker drops to zero). Returns annual USD saving, the USD opportunity cost of locking the required token balance (2026-09 snapshot price or explicit tokenPriceUsd override), payback in months, and the maximum one-year token price drop the saving can absorb. When tokenBalance is omitted it returns every achievable discount tier as a table with a recommended best-payback tier. Requires exchange, purpose, country, and monthlyVolumeUsd.

Returns per venue: consumer product name + fee model, modeled one-way all-in cost, measured round-trip, hidden markup pp, the PRO maker/taker base, the gap in pp, and — when monthly_volume_usd is passed — the annualized excess of using the consumer app instead of PRO (e.g. Coinbase at $1k/mo ≈ $168/yr); subscription caveats (Kraken+ $4.99/10k waiver, Coinbase One) and the fact that app volume earns NO PRO tier credit. Bitpanda/BISON have no separate PRO interface (the premium IS the fee); Bitstamp Basic is flagged unverified (no third-party measurement). Pass country to apply residency gating (Bitvavo/Bitpanda/BISON are venue-blocked outside their service areas). The same gap is auto-injected as consumer_interface hints into compare_exchange_fees / calculate_savings / compare_total_cost / recommend_exchange rows and as CONSUMER_INTERFACE_MORE_EXPENSIVE warnings on savings/recommendation results.

Runs each persona's full annual all-in stack across every allowed venue, then returns per-persona winner + realistic best_complete pick (every cost leg actually priced — headline winners with no fiat/withdrawal rail are demoted), a persona×venue annual-cost matrix, cross-persona venue win counts, and the single most versatile venue. Requires only the country; optionally restrict personas or force useToken. This is the fastest way to answer "which exchange for which kind of trader".

get_account_fee_tier ~530
当用户想知道"我账户里实际生效的手续费率/我的真实 VIP 档位费率/API 查我的 maker taker/为什么我实际手续费和公开表不一样"时使用。Use a READ-ONLY exchange API key (apiKey + secret, OKX/KuCoin-Futures also need passphrase as password; Hyperliquid needs only the PUBLIC 0x wallet address as apiKey) to fetch the account's ACTUAL maker/taker fee for spot or futures, then compares it against this server's bundled public VIP schedule at the given monthly volume and shows the gap in bps. Credentials are used per request only, never cached, never logged (audit logs redact them). Always generate a READ-ONLY key (no trading/withdrawal permissions). Supported: Binance, OKX, Gate, Bybit, MEXC, Bitget, KuCoin (spot + kucoinfutures), Kraken (spot + krakenfutures), Coinbase (spot), Hyperliquid (wallet address), BingX, Bitstamp (spot); NOT supported by the bundled ccxt connector: Phemex, BloFin, Bitstamp perps.

Returns per-exchange one-way execution cost in bps and USD for a specific order size (default $10,000): full spread, crossing cost (half spread), depth-walk slippage beyond the top level, total one-way cost, levels consumed, and fill status. spreadMode=bundled (default) uses offline typical-spread baselines by venue and pair class (majors/large-cap/mid-alt) instantly; spreadMode=live fetches the real top-100 order book per venue independently via ccxt and VWAP-walks it — failures fall back to bundled baselines (listed in failures), shallow books keep the measured cost with a warning. Spot requests use the spot market (e.g. kucoin rather than kucoinfutures). Requires country for compliance filtering unless exchanges are given explicitly.

recommend_exchange ~1,285
当用户不确定选哪个交易所、希望根据自身情况获得个性化推荐时使用。Use when the user wants a personalized exchange recommendation based on their trading volume, style, and holding habits. Scores available exchanges on weighted fees (maker/taker blend), token discounts, referral discounts, funding cost for futures, and (v0.27) the user's direct fiat deposit/cash-out habit — small monthly card/SEPA on-rampers get ranked on fiat rails too (the fiat weight grows 0.2→0.5 as venue-to-venue fiat-fee differences dominate trading-fee differences, and venues with no direct rail score zero on that leg rather than winning on an unpriced cost). Returns the best option with score, concrete reasons, tradeoffs, and actionable advice, plus ranked alternatives. Requires purpose, country, and volume.

当用户问"月交易量达到 X 手续费多少/如果成交量增长到不同水平呢/再刷多少量能升 VIP 档省钱/各交易所档位跳变点"，或要看一条跨成交量的费率-成本曲线时使用。Use for volume what-if / sensitivity analysis: scans monthly trading volume from zero up through the VIP ladder for spot OR futures across EVERY venue allowed in the country, returning (1) per-volume-point cross-venue ranking with the cheapest venue and its annual trading fee, (2) per-venue sweep curves with tier/maker/taker/weighted fee at each point, (3) the exact tier-crossing list (at which volume each venue moves to which rung), and when baseVolume is given, (4) each venue's next volume rung, how much MORE monthly volume it needs, and the USD/year it would save at the caller's current volume (holding-gated rungs like Binance spot's BNB requirement are explicitly flagged as unreachable by volume alone). Sweep points default to the union of every venue's tier thresholds (sampled if >16); pass explicit volumes for custom points. Applies referral discounts and the optional platform-token toggle exactly like compare_exchange_fees. Trading fees only — funding, spread, withdrawals and fiat are not included (use compare_total_cost for the full stack).
