How this service works
API usage - Secondary-measure weighted mean: Secondary-measure weighted mean for API usage. Up to 200 supplied typed records. Local numeric and data-quality processing; no external enrichment or forecasting. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded secondary-measure weighted mean deliverable.
Output
Returns a single weighted mean value computed by using one numeric field (e.g. latency_ms) as the measure and the other (e.g. requests) as the weight, across all supplied API usage records. The calculation is performed locally with no external enrichment.
Example use cases
Latency weighted by traffic volume
“I have daily API usage logs for two endpoints over the past week — each row has the date, endpoint name, request count, and average latency in milliseconds. Can you compute the weighted mean latency using request count as the weight so I know the true traffic-adjusted average response time? The field I care about is latency_ms.”
Request volume weighted average across endpoints
“Here are 50 rows of API usage data with endpoint names, dates, and request counts. Can you calculate the weighted mean of the requests field using latency_ms as the secondary weight? I want to understand which endpoints dominate by weighted volume.”
API performance summary for weekly report
“I'm putting together a weekly API performance report and need the secondary-measure weighted mean of latency_ms weighted by requests for these 12 data points across my three production endpoints. Can you run that calculation for me?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-sector-analytics-api-usage-weighted-average?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have tabular API usage data with request counts and latency values and need a statistically correct weighted mean rather than a simple arithmetic average. It is purpose-built for API analytics datasets with up to 200 records, processed locally without external dependencies. Prefer it over generic statistics APIs when your data matches the endpoint/date/requests/latency_ms schema exactly.
Side effects
- Empty or missing rows array returns validation error
- More than 200 rows submitted exceeds maxItems limit
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Null values in both requests and latency_ms for all rows may produce undefined result
- Invalid field enum value (not 'requests' or 'latency_ms') causes rejection
- row_id missing or empty string triggers required field error
