How this service works
Elevation samples — Base-100 series + Secondary-measure weighted mean: Base-100 series + 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
Returns two analytical reports: (1) a base-100 indexed series showing how each elevation_m value relates proportionally to the baseline row, and (2) a sample_weight-based weighted mean of the specified field — all computed locally with no external lookups, covering up to 200 input rows.
Example use cases
Baseline elevation normalization for survey stations
“I have 10 elevation readings from different survey stations with sample weights — can you generate a base-100 index series anchored to the first row and compute the weighted mean elevation across all of them?”
Weighted mean elevation for environmental study
“For my environmental study I have 50 elevation sample records each tagged with a date, station group, and sample weight — please compute the sample-weight weighted mean of elevation_m and the base-100 indexed series starting from row index 0.”
Multi-group elevation comparison with indexed series
“I've got elevation measurements split across two station groups over a month, each row has a weight — can you run the base-100 series and weighted mean reports on all 80 rows using elevation_m as the primary field and base index at row 0?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-weather-13-166?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have up to 200 elevation sample records with associated weights and need both a base-100 normalized index series and a weighted mean in a single $0.01 call, without requiring live data lookup, external APIs, or professional assessment — ideal for offline batch analytics on already-collected elevation or sensor data.
Side effects
- More than 200 rows submitted — request rejected due to maxItems constraint
- Missing required fields (row_id, station_group, date, elevation_m, sample_weight) — validation error
- Invalid date format (not YYYY-MM-DD) — schema pattern mismatch error
- base_index value out of range (0–199) — validation error
- Null values in elevation_m or sample_weight may affect weighted mean calculation
- Payment of 0.01 USDC not fulfilled — 402 Payment Required response
