Example use cases
Campaign lift measurement
“I ran a marketing campaign last quarter — before it my marketing spend was $10,000 and attributed contribution was $14,000, and after the campaign spend was $12,000 and contribution was $19,200. Can you compare the marketing contribution return before and after and tell me the absolute and relative change?”
Budget cut impact assessment
“We cut our marketing budget — before the cut we spent $80,000 with an attributed contribution of $120,000, and after the cut spend dropped to $60,000 with attributed contribution of $85,000. Show me how the marketing contribution return changed, including the formula and any limitations.”
Channel reallocation comparison
“We shifted spend to a new channel: previously marketing spend was $25,000 with attributed contribution of $30,000, and now spend is $25,000 with attributed contribution of $37,500. Compare the marketing contribution return before and after and give me the absolute and relative difference.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-finance-marketing-return-compare?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have exactly two data points — a before and after snapshot — and need a structured, formula-backed comparison of marketing contribution return with absolute and relative change. It is purpose-built for period-over-period or scenario-based marketing return comparisons, not for batch ranking, distribution analysis, or rolling averages (use sibling endpoints for those).
Side effects
- marketing_spend of zero or negative causes validation error (exclusiveMinimum:0)
- missing required fields (marketing_spend or attributed_contribution) in either before or after object returns error
- values exceeding max bounds (1,000,000,000,000) rejected
- mismatched currencies or periods not detected — garbage-in garbage-out
- network or payment failure returns no result
