optionsahoy-openai-agents

OpenAI Agents SDK tools for the OptionsAhoy equity-compensation calculators. One FunctionTool per OptionsAhoy REST endpoint, built on the keyless optionsahoy client. No OptionsAhoy account, no application programming interface (API) key, full federal tax code plus all 50 states and the District of Columbia (DC).

Why not just ask the model?

We benchmarked five frontier large language models (LLMs), 3 runs each, 15 trials total, on the same multi-year incentive stock option (ISO) exercise problem. Every trial overshot the true after-tax outcome, by 2x to 20x. See the benchmark, updated for the latest models, at https://optionsahoy.com/benchmark. Multi-year scheduling has a search space larger than an LLM can reason through in-context; these tools return the verifiable answer instead.

Raw responses and scoring: llm-iso-benchmark. Full write-up: But can it do taxes though?.

Verified

Beyond determinism, the tax math is independently verified, every release: every 2026 federal constant matches its IRS Rev. Proc. 2025-32 value, worked federal cases reproduce to the cent against the independently-maintained PSL Tax-Calculator, and state tax reproduces to the cent against OpenTaxSolver across CA, NY, NJ, PA, and MA, with the headline answer recomputed live in your browser.

What it provides

get_optionsahoy_tools() returns seven FunctionTools, each with a JSON schema mirroring its endpoint:

• optionsahoy_amt_iso_optimize - multi-year ISO exercise optimizer under the alternative minimum tax (AMT)
• optionsahoy_nso_calculate - non-qualified stock option (NSO) exercise tax, sell-at-exercise versus hold
• optionsahoy_rsu_sell_vs_hold - restricted stock unit (RSU) sell at vest versus hold for long-term capital gains
• optionsahoy_concentration_analyze - single-stock concentration risk and the after-tax cost of diversifying
• optionsahoy_protective_put_price - protective put, zero-cost collar, and put spread pricing
• optionsahoy_qsbs_check - qualified small business stock (QSBS) Section 1202 eligibility and exclusion
• optionsahoy_equity_funding_plan - multi-year plan to fund a cash goal from equity by a target date

Each tool returns an independent calculation for one decision. They are not a single joint optimization across your whole equity portfolio; the integrated, cross-asset optimizer is the OptionsAhoy product, currently in invite-only beta.

Coverage spans the full federal tax code plus all 50 states and DC. The adapter pulls in the keyless optionsahoy client automatically. No API key is read, stored, or sent anywhere.

Install

pip install optionsahoy-openai-agents

This pulls in openai-agents and the keyless optionsahoy client.

Quickstart

Attach the tools to an Agent and run it. The Agents SDK calls the tools; you bring your own model key (for example OPENAI_API_KEY).

import asyncio

from agents import Agent, Runner

from optionsahoy_openai_agents import get_optionsahoy_tools

agent = Agent(
    name="Equity assistant",
    instructions=(
        "You are an equity-compensation assistant. Use the OptionsAhoy tools to "
        "compute exact tax-aware answers; do not estimate the math yourself."
    ),
    tools=get_optionsahoy_tools(),
)

prompt = (
    "I have 8000 ISOs at a $3 strike, current fair market value $40, granted "
    "2022-03-01, still employed. I file single in California with $250000 of "
    "ordinary income, no AMT carryforward, 4% cash return, 5-year horizon, and "
    "expect 12% annual growth at 50% volatility. How many shares should I "
    "exercise each year?"
)

result = asyncio.run(Runner.run(agent, prompt))
print(result.final_output)

Pass your own configured client with get_optionsahoy_tools(client=OptionsAhoyClient(...)).

The seven endpoints accept forward-looking fields (such as expectedSalePrice or volatility) that the schema marks optional but the API requires at call time; set a covered ticker (for example "NVDA") to let the API derive them, or pass explicit values. Omitting both returns a clear 400 explaining which field is needed.

To read the full input schema for any tool, inspect tools[0].params_json_schema (substitute the tool you want). The authoritative request schemas are the OpenAPI spec at https://optionsahoy.com/openapi.json and the agent docs at https://optionsahoy.com/for-agents.
