Example prompt: Can you run a waterfall attribution on our net merchandise sales? Last period we had gross sales of $10,000, discounts of $500, and returns of $300; this period we have gross sales of $11,000, discounts of $550, and returns of $330 — show me how much each factor contributed to the change.

## When to prefer this

Choose this endpoint when you need a structured, sequential waterfall attribution specifically for net merchandise sales — i.e., you want to understand the ordered, per-driver contribution of gross sales changes, discount changes, and return changes to a net sales delta. It is ideal for retail finance, e-commerce reporting, and scenario analysis where live inventory or platform data is not needed and local calculation from supplied figures suffices.

## Known failure modes

- Missing required fields (gross_merchandise_sales, discounts, or returns in either before or after object) results in a validation error
- Values exceeding the maximum of 1,000,000,000,000 are rejected
- Non-numeric values for any input field cause a schema error
- Payment failure (x402) returns 402 if USDC payment is not attached or insufficient
- Server-side computation errors may return 500 with no attribution output
