How this service works
Bundle contribution - Sequential input-change attribution: Sequential input-change attribution for Bundle contribution. Supplied retail figures only. Local calculation and scenario analysis; no live inventory, account access, platform fee lookup or order execution. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded sequential input-change attribution deliverable.
Output
A sequential (waterfall) attribution breakdown showing how each input change — bundle price, item costs, packing cost, and fulfilment cost — individually contributed to the total change in bundle contribution margin between the before and after states, calculated locally from the supplied retail figures.
Example use cases
Diagnosing a margin squeeze on a retail bundle
“Our premium gift bundle contribution dropped this quarter — price went from $150 to $145, item costs rose from $70 to $80, packing stayed at $8, and fulfilment went from $12 to $15. Run a sequential waterfall so I can see which input change hit the margin hardest.”
Evaluating a bundle repricing decision
“We're raising our bundle price from $200 to $220 while item costs stay at $90, packing at $10, and fulfilment at $18. Can you do a sequential attribution to show how much of the contribution change comes purely from the price increase versus any cost movement?”
Scenario planning before a cost restructure
“Before we renegotiate supplier contracts, I want to model the impact: current state is $120 bundle price, $60 item costs, $6 packing, $14 fulfilment; new state would be $120 price, $52 item costs, $6 packing, $14 fulfilment. Run the sequential waterfall to quantify the contribution improvement attributable to the item cost reduction.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-sector-retail-bundle-contribution-waterfall?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to understand the sequential, step-by-step attribution of how specific cost and price changes drove a shift in retail bundle contribution margin. It is ideal for scenario analysis and explaining margin variances without needing live inventory, platform fee, or account data. Prefer it over generic margin calculators when you specifically want a waterfall decomposition that isolates each input's individual contribution to the total change.
Side effects
- Missing required fields (bundle_price, item_costs, packing_cost, fulfilment_cost) in before or after objects returns a validation error
- Negative values or values exceeding 1,000,000,000,000 are rejected by schema constraints
- Payment of 0.01 USDC not completed via x402 protocol results in 402 Payment Required response
- Malformed JSON body returns a 400 Bad Request error
