Example use cases
Multi-SKU contribution margin audit
“I have a list of 50 products with their unit prices and variable costs — can you batch calculate the unit contribution for all of them and flag any rows with bad data?”
Pricing scenario comparison
“Run a batch unit contribution calculation for these five pricing scenarios: unit prices of $15, $18, $20, $25, $30 with corresponding variable costs of $9, $11, $13, $16, $20.”
Product line profitability check
“Calculate unit contribution for our three product lines — Line A: price $45, variable cost $28; Line B: price $60, variable cost $41; Line C: price $30, variable cost $19 — and return the formula and any limitations.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-finance-unit-contribution-batch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to process multiple unit contribution calculations in a single call (up to 200 rows), especially when you also need automatic validation of bad rows and a structured JSON report with the formula and units. Prefer this over a single-record calculator when working with product catalogs, pricing grids, or scenario tables.
Side effects
- Rows missing required fields (unit_price or variable_cost_per_unit) are flagged as invalid rather than causing a full failure
- Batch exceeds 200 rows — request rejected with maxItems validation error
- Values outside allowed range (0 to 1,000,000,000,000) will be flagged or rejected
- Payment not completed — endpoint returns 402 before processing
- Malformed JSON body — returns parse error
