x402
Elevation Samples — Two-Measure Correlation + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-02).
Computes Pearson/rank correlation between elevation_m and sample_weight, plus a weighted mean of sample_weight, for up to 200 supplied elevation sample rows — no external data fetched.

How this service works
Elevation samples — Two-measure correlation + Secondary-measure weighted mean: Two-measure correlation + 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 correlation coefficient measuring the linear relationship between elevation_m and sample_weight across all supplied rows, and (2) a weighted mean of the secondary measure (sample_weight), computed locally without any external data fetch or prediction.
Example use cases
Elevation-weight relationship check
“I have 150 weather station elevation readings with sample weights — can you compute the correlation between elevation_m and sample_weight and give me the weighted mean of the sample_weight column?”
Station group data quality validation
“Run a correlation and weighted mean analysis on these 80 elevation sample records across my two station groups (group-a and group-b) so I can see if elevation and weight are related.”
Temporal elevation sampling summary
“I collected daily elevation samples from October 2026 across four sites — please compute the two-measure correlation between elevation_m and sample_weight, and the secondary-measure weighted mean, for all 200 rows.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-weather-13-181?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have tabular elevation sample data with associated weights and need both a correlation statistic and a weighted mean in a single API call, without requiring external data sources, predictions, or live lookups. It is especially useful for offline or batch analytical pipelines where two statistical reports are needed cheaply ($0.01 per call) on small datasets up to 200 rows.
Side effects
- Rows array empty or missing — validation error returned
- More than 200 rows submitted — request rejected with max-items error
- Non-numeric or null values in elevation_m or sample_weight may reduce report accuracy or return nulls
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Payment not included or insufficient USDC — x402 payment required error
