How this service works
Transport ridership — Category frequencies + Equal-width histogram: Category frequencies + Equal-width histogram for supplied transport ridership records (passenger_count, service_count). 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) category frequencies showing how often each region (or category value) appears in the dataset, and (2) an equal-width histogram dividing the selected numeric field (passenger_count or service_count) into the specified number of bins with counts per bin. Both reports are computed locally against the supplied rows with no external data lookups.
Example use cases
Regional ridership frequency audit
“I have 50 rows of daily transit data with region, date, passenger_count, and service_count. Can you give me the category frequencies by region and a 10-bin histogram of passenger_count so I can see which regions are busiest?”
Service count distribution for planning
“Here are 120 records of bus service data with row_id, region, date, passenger_count, and service_count fields. Generate a category frequency table and a 5-bin equal-width histogram for service_count so I can understand the distribution.”
Ridership histogram for weekly report
“I need to summarize this week's transit ridership — I have 30 rows with passenger counts and service counts by region. Give me the category frequencies and a 7-bin histogram of passenger_count for the report.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-economics-05-106?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have raw transport ridership records (up to 200 rows) and need two quick statistical summaries — category frequencies and a numeric histogram — in a single call without any external data lookup or prediction. It is ideal for lightweight, local analytics on pre-collected transit datasets where you want both a categorical breakdown by region and a distribution view of passenger or service counts simultaneously.
Side effects
- More than 200 rows submitted — request will be rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes row validation failure
- Missing required fields (row_id, region, date, passenger_count, service_count) cause schema rejection
- bins value outside 1–30 range causes parameter error
- All values null for selected field produces empty or degenerate histogram
- Payment of 0.01 USDC not included causes 402 response
