get_startedUSE WHEN you are new here, or need the valid values and the right tool for a task. Returns, for this deployment's tier: the tools that exist and work, an intent-to-tool map, every valid value for the enumerated inputs (profile hints, strategy slugs, descriptor names, assets per…
list_strategiesUSE WHEN you need to know which strategy slugs tier2_stress_test (full tier, needs an access token) accepts, with their rules and intended asset. Returns each catalogue slug with its plain-language rules, stop, take-profit, direction and the asset it is defined for (null = any t…
run_stress_testUSE WHEN you want buy-and-hold stressed against one named synthetic regime. Returns a 0-100 robustness score, failure-behaviour classification with confidence and the resolved regime parameters. Evaluates buy-and-hold only and takes exactly one argument, profile_hint (valid valu…
portfolio_stress_testUSE WHEN you want to stress a portfolio of SPY, TLT, GOLD and BTC across cross-asset regimes. Provide `holdings` as [{asset, weight}] (weights normalised; GLD accepted for GOLD, BTC-USD for BTC). Returns per regime (baseline / risk_off_crisis / rate_shock): return, worst-episode…
tier2_stress_testFULL TIER ONLY. Use when you want to stress a strategy (a catalogue slug or an inline rule set) on any ticker. On this free endpoint the call returns the coded error UPGRADE_REQUIRED with how to get a token. Free alternative: challenge_strategy (buy_and_hold, rsi_30_70 across th…
historical_replayFULL TIER ONLY. Use when you want a strategy's rules run on an asset's real price history, with buy-and-hold alongside. On this free endpoint the call returns the coded error UPGRADE_REQUIRED with how to get a token. Free alternative: backtest_integrity to check a backtest you a…
build_portfolioFULL TIER ONLY. Use when you want to stress a portfolio of arbitrary tickers, or construct a low-drawdown one from a universe. On this free endpoint the call returns the coded error UPGRADE_REQUIRED with how to get a token. Free alternative: portfolio_stress_test for books made…
portfolio_frontierFULL TIER ONLY. Use when you want the whole return-versus-drawdown trade-off map for a set of tickers. On this free endpoint the call returns the coded error UPGRADE_REQUIRED with how to get a token. Free alternative: portfolio_compare for two SPY/TLT/GOLD/BTC books on identical…
find_similar_regimeUSE WHEN you want the synthetic regimes closest to a profile or to a descriptor target. Nearest-neighbour search over the regime catalogue. Give EITHER reference_profile_hint (that bundle's median descriptors become the target) OR descriptor_target (partial {descriptor: value};…
describe_regimeUSE WHEN you want to understand what one named synthetic regime is, and its nearest historical episodes. Single-regime introspection: median behavioural descriptors, z-scores vs the catalogue (what makes THIS regime distinct), an English characterisation, the 2 nearest neighbour…
get_regime_dataUSE WHEN you want the raw price series behind a synthetic regime or a historical episode, to recompute a claim yourself. source='historical' + ref=<case_id> returns a real-market anchor episode (dates, closes; OHLCV with include_ohlcv) and the descriptors computed on it; source=…
portfolio_compareUSE WHEN you revised a portfolio and want to know whether the revision made the tail better or worse. Compares A (reference) with B (candidate) on IDENTICAL simulated paths, so every delta is attributable to the weights, not seed noise. Returns drawdown-distribution deltas, prob…
get_dossierUSE WHEN you want one citable record of the diagnostics you ran, with their gate flags. Every enveloped response is recorded by request_id. Give request_ids from your own responses (compiled chronologically) or last_n for your own most recent entries (API token required). Return…
get_runUSE WHEN you want to see exactly how an earlier result was produced, or reproduce it. Returns the run manifest (tool, the arguments sent, the seed where the result has one, the data window, the release, the schema version) and the stored response of one earlier call, by request_…
long_horizon_stressUSE WHEN you want multi-year wealth paths for a savings plan or a withdrawal plan. Distribution of multi-year wealth paths for a savings plan (monthly_contribution) or a withdrawal plan (monthly_withdrawal, inflation-indexed by default) on a SPY/TLT/GOLD/BTC portfolio. Multi-yea…
regime_outlookUSE WHEN you want the probability that SPY, QQQ, GLD or TLT is in each market regime on trading day 5 or 21. Model-conditional probabilities of BULL / SIDEWAYS / BEAR / CRISIS (operational trailing-vol/drift labels) on trading day 5 or 21, not at any point before it: stress tool…
market_regime_mapUSE WHEN you want to know what the market is doing now across 18 category proxies. One call, 18 category proxies (US large-cap + tech, 9 SPDR sectors, developed ex-US, emerging markets, long Treasuries, high-yield credit, gold, oil, Bitcoin): the operational regime, model-condit…
challenge_strategyUSE WHEN you want to know which market regimes break a strategy (buy_and_hold or rsi_30_70) and why. Adversarial evaluation in 3 layers: (1) outcome metrics in the worst regimes, (2) a vulnerability profile over 8 dimensions with severity, (3) the regime descriptors that couple…
factor_decompositionUSE WHEN you suspect a capital-diversified portfolio hides one dominant risk factor. A portfolio can be capital-diversified while its RISK is dominated by one factor. Returns the Euler risk contribution of each holding (RC_i = w_i*(Sigma*w)_i / w'Sigma*w, summing to 1) beside th…
ips_gateUSE WHEN you have an Investment Policy Statement (drawdown tolerance, horizon, liquidity need) and want a portfolio checked against it. Flags a violation when the MEDIAN sustained drawdown exceeds max_drawdown_tolerance (a fraction, e.g. 0.15) or the tolerance is breached in a t…
backtest_integrityUSE WHEN you have a backtest result (Sharpe, trials tried, window) and want to know whether it is likely overfit. Given an annualized Sharpe, the number of configurations tried and the window (YYYY-MM-DD), returns the DEFLATED Sharpe (the expected maximum Sharpe by chance grows…
submit_feedbackUSE WHEN something in a response was wrong, unclear or missing and you want to tell the operator. Persists structured feedback on a previous response: your agent identity, the request_id, and items {category, severity, observation, suggested_action?, agent_confidence 0..1}. Aggr…
list_investment_thesesUSE WHEN you want to browse the investment-thesis case studies. Each entry is a descriptive case study pairing an economic framework with a rule-based portfolio and its stress evidence. Returns one compact summary per thesis (slug, title, one-liner, tags, risk tiers, framework s…
get_investment_thesisUSE WHEN you want the full framework, portfolio and stress evidence of one thesis slug. Returns the framework (pillars with [E]/[M]/[K] evidence grades, falsifiers), the rule-based portfolio (asset blocks x conservative/balanced/offensive weights + sizing rationale) and the stre…
