Example use cases
Blended campaign performance summary
“I have five marketing campaigns with different spend and revenue attribution — can you calculate the weighted mean marketing contribution return using weights 1, 3, 2, 3, 1 for campaigns with spends of $4,000, $6,000, $5,500, $7,000, $4,500 and attributed contributions of $6,500, $10,200, $8,800, $12,000, $7,100? I need the formula and units too.”
Quarterly channel performance aggregation
“Aggregate our Q3 marketing contribution return across three channels — digital ($20,000 spend, $34,000 attributed; weight 3), print ($8,000 spend, $11,000 attributed; weight 1), and events ($15,000 spend, $27,000 attributed; weight 2) — and give me the weighted mean with limitations noted.”
Year-over-year weighted return comparison
“Can you compute the weighted mean marketing contribution return for two consecutive years? Year 1: $50,000 spend with $80,000 attributed (weight 1), Year 2: $55,000 spend with $95,000 attributed (weight 2). Include the formula and any caveats in the output.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-finance-marketing-return-weighted-mean?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a statistically weighted aggregate of marketing contribution return across multiple campaigns, periods, or channels, and you want to assign non-equal importance weights to each data point. It is ideal for blended reporting where different campaigns have different sample sizes or strategic priorities. Prefer it over a simple mean when equal weighting would misrepresent your data.
Side effects
- Weights array length does not match rows array length — mismatch error returned
- Fewer than 2 rows supplied — minimum items validation failure
- Marketing spend of zero or negative — excluded by exclusiveMinimum constraint
- Weight values are negative — validation error since weights must be non-negative
- More than 200 rows submitted — maxItems constraint violation
- Non-numeric values in spend, contribution, or weight fields — schema type error
