How this service works
Elevation samples — Category frequencies + Secondary-measure weighted mean: Category frequencies + Secondary-measure weighted mean for supplied elevation samples records (elevation_m, sample_weight). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.
Output
Two analytical reports: (1) category frequencies showing how often each elevation category appears across the supplied rows, and (2) a weighted mean of the selected numeric field (elevation_m or sample_weight) computed using the sample_weight values as weights. Results are derived entirely from the supplied data with no external lookups.
Example use cases
Station group elevation frequency audit
“I have 50 elevation readings from two weather station groups collected this month — can you compute the category frequencies and sample-weight weighted mean for the elevation_m values so I can see how the readings are distributed across groups?”
Terrain survey weighted average analysis
“I've got 120 terrain survey samples with elevation in meters and a reliability weight for each row — please run the category frequency report and the weighted mean report on the elevation_m field using those reliability weights.”
Environmental monitoring data summary
“Here are 80 elevation sample records from our environmental monitoring network with dates, station groups, elevation in meters, and sample weights — give me two reports: the category frequencies and the secondary-measure weighted mean for elevation_m.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-weather-13-109?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have up to 200 elevation sample records and need both a category frequency distribution and a sample-weight-based weighted mean in a single call for $0.01 USDC. It is ideal for offline analytical summarization of geospatial or environmental survey data where no live lookup, external data enrichment, or prediction is required — just fast, local statistical computation on supplied rows.
Side effects
- More than 200 rows submitted — request exceeds the row limit and will be rejected
- Missing required fields (row_id, station_group, date, elevation_m, sample_weight) cause validation errors
- Invalid date format (must match YYYY-MM-DD pattern) triggers schema rejection
- All sample_weight values are null or zero — weighted mean computation may be undefined
- Malformed JSON body returns a 400-level error
- Insufficient USDC balance or failed x402 payment prevents processing
