How this service works
Proposal preparation — Daily sum series + Two-measure correlation: Daily sum series + Two-measure correlation for supplied proposal preparation records (completed_sections, planned_sections). 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 daily sum time series aggregating the selected field (completed_sections or planned_sections) by date, and (2) a two-measure correlation between completed_sections and planned_sections across the supplied rows. Both reports are computed locally on up to 200 input rows with no external lookups or predictions.
Example use cases
Proposal completion trend analysis
“I have 4 weeks of daily proposal writing data with completed_sections and planned_sections for two document groups — can you give me the daily sum series and show me how strongly these two measures correlate?”
Cross-team document progress comparison
“We track planned_sections and completed_sections for proposals across multiple groups each day. Can you aggregate the daily totals and run a two-measure correlation on that data for the last 30 rows?”
Proposal planning accuracy assessment
“I want to check how well our planning aligns with actual completion on proposals — run a daily sum series on completed_sections and correlate it with planned_sections using this dataset of about 100 rows.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-writing-08-141?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have tabular proposal preparation records with daily timestamps and two numeric measures (completed_sections, planned_sections) and need both a time-aggregated daily sum series and a statistical correlation between those two measures in a single low-cost call. It is ideal for lightweight, self-contained analytics on up to 200 rows without requiring an external analytics platform or data warehouse.
Side effects
- Input array exceeds 200 rows — request will be rejected or truncated
- Missing required fields (row_id, date, document_group, completed_sections, planned_sections) cause validation errors
- Invalid date format (must be YYYY-MM-DD) causes schema rejection
- Null values in numeric fields may affect correlation computation
- Empty input array (minItems: 1 not met) returns an error
- Insufficient date variation for meaningful time series if all rows share the same date
