How this service works
Proposal preparation — Equal-width histogram + Explicit missing-value fill: Equal-width histogram + Explicit missing-value fill 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) an equal-width histogram showing bin boundaries and row counts for the selected numeric field (completed_sections or planned_sections), and (2) a missing-value fill report showing how null values in that field were replaced using the chosen strategy (zero, mean, or median). Both reports are computed locally with no external lookups.
Example use cases
Proposal completion distribution analysis
“I have 120 proposal records with completed_sections and planned_sections values — some are null. Can you bucket the completed_sections into 8 equal-width bins and fill the missing values using the mean so I can see the distribution?”
Grant writing progress audit
“Here are 60 rows of grant proposal tracking data with dates, document groups, row IDs, and section counts. Fill any missing planned_sections values using zero and give me a 10-bin histogram so I can spot where most proposals are concentrated.”
Multi-group proposal milestone review
“I need to review section completion across two proposal groups — group-alpha and group-beta. Can you run a histogram with 5 bins and median fill on the completed_sections field for these 80 records?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-writing-08-175?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have proposal preparation records with completed_sections and/or planned_sections fields and need both a frequency distribution (histogram) and missing-value imputation in a single call for up to 200 rows. It is ideal for lightweight, local statistical summarization without needing a full analytics platform or live data connection.
Side effects
- Exceeding 200 rows returns a validation error
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Numeric values outside ±1,000,000,000,000 are rejected
- Missing required fields (row_id, date, document_group) cause row-level errors
- bins value below 1 or above 30 is rejected
- Payment failure or insufficient USDC balance blocks the call
