Example prompt: Can you run a full WACC build for FBIO using their SEC filings for the fiscal year ending December 31 2025 — I want the CAPM cost of equity, tranche-level cost of debt, capital structure weights, and the filing citations, returned as JSON.

## When to prefer this

Use this endpoint when you need a reproducible, auditable WACC for FBIO specifically anchored to fiscal year-end 2025-12-31, with every assumption traceable to a specific SEC filing line item. Prefer this over generic financial data APIs when citation quality, determinism, and tranche-level debt granularity matter — e.g. for DCF models, fairness opinions, or due diligence workflows.

## Known failure modes

- FBIO ticker not found or no matching 10-K filing for the specified FYE — returns 404 or error JSON
- Insufficient filing data to construct full WACC (e.g. missing debt schedule) — returns partial result with warning
- Payment not confirmed (x402 protocol failure) — request rejected before computation
- Invalid or malformed fiscal year-end date parameter — returns 400 validation error
- Filing data not yet available for the requested period — returns data-unavailable error
