Read-onlyIdempotent

Calculate option prices, Greeks, and implied volatility using Black-Scholes, binomial, Monte Carlo, and exotic option models for any ticker.

Instructions

Option pricing and Greeks (Black-Scholes model, binomial tree, delta, gamma, theta, vega, rho, implied volatility). Requires tickers='AAPL' — use comma-separated values for multiple tickers.

Available indicators: get_asian_option, get_barrier_option, get_binary_option, get_binomial_model, get_bjerksund_stensland, get_black_scholes_model, get_charm, get_color, get_delta, get_dual_delta, get_dual_gamma, get_epsilon, get_gamma, get_garman_kohlhagen, get_implied_volatility, get_lambda, get_monte_carlo_option_price, get_option_chains, get_partial_derivative, get_put_call_parity, get_rho, get_risk_neutral_density, get_speed, get_stock_price_simulation, get_strategy_payoff, get_theta, get_ultima, get_vanna, get_vega, get_vera, get_veta, get_volatility_surface, get_vomma, get_zomma.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
legsNoValue for legs. Leave unset to use the default of the indicator you selected. Required by: get_strategy_payoff.
seedNoValue for seed.
rebateNoValue for rebate.
tickersNoComma-separated ticker symbols, e.g. 'AAPL,MSFT,GOOGL'.
end_dateNoEnd of the date range in YYYY-MM-DD format.2026-08-19
indicatorYesName of the specific metric to calculate, e.g. 'get_asset_turnover_ratio'. Required — omitting it returns the list of available indicators.
quarterlyNoReturn quarterly data instead of annual when True.
timestepsNoValue for timesteps.
knock_typeNoValue for knock_type.out
put_optionNoValue for put_option.
start_dateNoStart of the date range in YYYY-MM-DD format.2021-08-20
time_stepsNoValue for time_steps.
cash_payoutNoValue for cash_payout.
option_typeNoValue for option_type.cash-or-nothing
simulationsNoValue for simulations.
standardizeNoReturn the Z-Score (standard score) instead of the raw values, i.e. how many standard deviations each value is from the mean of its own series. When combined with growth=True, the growth values are standardized instead of the raw values.
show_columnsNoComma-separated names to filter the output. For historical data use the key names visible in any response record (e.g. 'Close,Volume,Return'). For financial statements use the 'metric' field values from the response (e.g. 'Revenue,Net Income,EBITDA'). Call the tool once without this parameter to see all available names, then repeat with show_columns to reduce response size and token usage.
dividend_yieldNoValue for dividend_yield.
risk_free_rateNoValue for risk_free_rate.
american_optionNoValue for american_option.
expiration_dateNoValue for expiration_date.
show_input_infoNoValue for show_input_info.

expiration_datesNoValue for expiration_dates.
strike_step_sizeNoValue for strike_step_size.
barrier_directionNoValue for barrier_direction.down
number_of_strikesNoValue for number_of_strikes.
outlier_thresholdNoValue for outlier_threshold.
stock_price_rangeNoValue for stock_price_range.
barrier_percentageNoValue for barrier_percentage.
strike_price_rangeNoValue for strike_price_range. Leave unset to use the default of the indicator you selected. Defaults differ between indicators.
time_to_expirationNoValue for time_to_expiration.
show_standard_errorNoValue for show_standard_error.
expiration_time_rangeNoValue for expiration_time_range.
number_of_expirationsNoValue for number_of_expirations.

  6. Addedv0.1.1

TDQS

B3.3/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, so the safety profile is established. The description adds only the tickers requirement and indicator list, but no deeper behavior like error handling, return format, or rate limits, so it meets but doesn't exceed expectations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The first sentence is front-loaded and informative, but the long list of indicators duplicates the enum in the input schema, creating redundancy and length. This list adds bulk without explaining each indicator or its parameters.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 39 parameters and 34 possible indicators, the description should explain which parameters apply to which indicator. It only provides a flat list of indicators and a ticker requirement; parameter-indicator mapping is left entirely to the schema, which has many tautological descriptions. An output schema exists but return semantics are not described.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema provides 100% description coverage, so the baseline is 3. The description adds guidance on tickers ("Requires tickers='AAPL'") and lists indicators, but most parameters remain poorly explained with generic "Value for X" schema descriptions; the description does not compensate for the 30+ parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description explicitly states "Option pricing and Greeks (Black-Scholes model, binomial tree, delta, gamma, theta, vega, rho, implied volatility)", which clearly identifies the tool's domain and distinguishes it from broader siblings like volatility or models. It also enumerates 34 available indicators, making the scope concrete. However, it lacks an explicit verb, so it's not a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives clear usage context with "Requires tickers='AAPL' — use comma-separated values for multiple tickers," and lists the available indicators to choose from. It does not explicitly name alternatives or when-not-to-use, but the context is sufficient for a domain-specific tool.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
