Use this endpoint when an agent needs a quick, on-demand tax estimate without requiring a full tax-filing integration or jurisdiction-specific tax API. Best for rough estimates based on described financial scenarios like freelance income, crypto gains, or capital gains.
Side effects
- Vague or ambiguous query yields generic or unhelpful estimate
- Missing income or jurisdiction details may reduce accuracy
- Overly broad query string returns partial or placeholder data
- Payment failure (402) if USDC balance is insufficient
- Service unavailability returns 5xx error
