```

Example prompt: Can you calculate the ROI and payback period for adding a Tesla Powerwall to my home solar system in California, factoring in the IRA 30% federal tax credit and any state incentives?

## When to prefer this

Choose this endpoint when a user wants a homeowner-focused financial analysis of battery storage investment, specifically needing IRA tax credit calculations and state incentive stacking, and when comparing Powerwall against competing battery products. Best for solar agents and homeowner assistants needing ROI and payback data rather than raw electricity pricing.

## Known failure modes

- Unsupported or unrecognized state code returns error or empty incentive data
- Missing required parameters (state, usage) returns 400 Bad Request
- No state incentives available for the specified location returns zero state incentive value
- Battery product not recognized returns comparison with only available alternatives
- Payment not processed (x402 flow failure) returns 402 Payment Required
