How this service works
Commercial proposal comparisons — Adjacent row changes + Two-measure correlation: Adjacent row changes + Two-measure correlation for supplied commercial proposal comparisons records (quoted_amount, delivery_days). 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 derived from the supplied rows: (1) an adjacent row changes report showing sequential differences in the selected measure (quoted_amount or delivery_days) across rows, and (2) a two-measure correlation report quantifying the statistical relationship between quoted_amount and delivery_days. No external data is fetched; all computation is performed locally on the provided dataset.
Example use cases
Vendor bid sequence trend analysis
“I've collected 80 procurement proposals from two supplier groups over the past quarter, each with a quoted amount and delivery days. Can you analyze the adjacent row changes in quoted_amount and also run a correlation between quoted_amount and delivery_days so I can see how prices shift sequentially and whether faster delivery costs more?”
Detecting price drift across proposal rounds
“We have 120 rows of commercial proposal data from three company groups, dated over six months. Can you check how quoted_amount changes between consecutive rows and compute the correlation between quoted_amount and delivery_days to help us spot price drift?”
Procurement analytics for supplier comparison
“Here are 40 proposal records from two competing vendors with their quoted_amount and delivery_days — can you run the adjacent row changes report and two-measure correlation for quoted_amount so I can compare how their bids evolve and whether delivery time influences pricing?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-company-24-158?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need simultaneous adjacent row change detection and two-measure correlation on commercial proposal or procurement bid data (quoted_amount, delivery_days) for up to 200 rows at very low cost ($0.01 USDC for both reports). It is ideal when you have structured tabular proposal data ready to supply and want purely local statistical analysis without any external lookups, predictions, or professional assessments. Prefer alternatives if you need more than 200 rows, more than two measures, real-time data enrichment, or predictive modeling.
Side effects
- Fewer than 1 row submitted — minimum row count not met
- More than 200 rows submitted — exceeds maximum row limit
- Missing required fields (row_id, company_group, date, quoted_amount, delivery_days) on any row
- Invalid date format (must be YYYY-MM-DD)
- Numeric values outside allowed range (-1,000,000,000,000 to 1,000,000,000,000)
- Invalid field enum value (must be 'quoted_amount' or 'delivery_days')
- All values null for the selected measure — correlation or change detection cannot be computed
