x402
API Contracts — 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 2026-10-29).
Computes Pearson/rank correlation between fields_checked and incompatible_fields, plus a weighted mean of a chosen secondary measure, across up to 200 API contract records.

How this service works
API contracts — Two-measure correlation + Secondary-measure weighted mean: Two-measure correlation + Secondary-measure weighted mean for supplied api contracts records (fields_checked, incompatible_fields). 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 (and supporting stats) between fields_checked and incompatible_fields across the supplied rows, and (2) a weighted mean of the selected secondary measure (fields_checked or incompatible_fields) across the same dataset. Both reports are computed locally from the supplied data with no external lookups.
Example use cases
API compatibility audit statistical review
“I've got a set of API contract audit records — each row has a component name, date, number of fields checked, and number of incompatible fields. Can you run a correlation between fields_checked and incompatible_fields and also compute the weighted mean of incompatible_fields across all 150 rows?”
Schema change impact analysis
“After our last API version bump I have 80 contract check records tagged by component and date. Can you tell me how strongly fields_checked correlates with incompatible_fields, and what the weighted mean of fields_checked looks like across those records?”
Multi-team API health comparison
“I have contract data for two groups — group-a and group-b — across 60 rows, each with fields_checked and incompatible_fields counts. Please compute the correlation between those two measures and give me the weighted mean of incompatible_fields so I can compare team quality.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-software-19-181?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have up to 200 rows of API contract records with numeric fields_checked and incompatible_fields columns and need two statistical outputs — a correlation and a weighted mean — in a single low-cost call ($0.01 USDC). Ideal for lightweight offline analytics on contract audit exports without needing a full data warehouse or external computation service.
Side effects
- Fewer than 1 row supplied — request rejected due to minItems:1 constraint
- More than 200 rows supplied — request rejected due to maxItems:200 constraint
- Missing required fields (row_id, fields_checked, incompatible_fields, date, component) — validation error
- Invalid date format (not YYYY-MM-DD) — schema pattern mismatch
- Numeric values outside ±1,000,000,000,000 range — schema validation error
- Null values for both measures across all rows — correlation undefined or NaN result
