How this service works
Specification traceability — Category frequencies + Two-measure correlation: Category frequencies + Two-measure correlation for supplied specification traceability records (mapped_requirements, total_requirements). 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
Two analytical reports: (1) a frequency count of records per document_group category, and (2) a Pearson or equivalent correlation coefficient between the mapped_requirements and total_requirements numeric columns, computed locally on the supplied rows without any external lookups.
Example use cases
Requirements coverage audit across document groups
“I have our traceability export with rows for each spec document — each row has a document_group, a date, and counts for mapped_requirements and total_requirements. Can you tell me how many rows fall into each document group and whether there's a strong correlation between mapped and total requirements?”
Sprint traceability health check
“Here are our sprint's specification traceability records with document groups and requirement counts. Run category frequencies on the document groups and compute the correlation between mapped_requirements and total_requirements so I can see how well we're tracking coverage.”
Compliance traceability statistical summary
“We need a statistical summary of our compliance traceability dataset — it has up to 150 rows with fields for document_group, date, mapped_requirements, and total_requirements. Give me the frequency of each document category and the correlation between the two requirement measures.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-writing-21-108?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have specification traceability records with numeric requirement counts and categorical document groupings and need both a distribution summary (frequencies) and a linear relationship measure (correlation) in a single low-cost call. Ideal for compliance teams, QA engineers, and requirements analysts who want a quick statistical snapshot without standing up their own analytics pipeline.
Side effects
- Missing required fields (row_id, document_group, date, mapped_requirements, or total_requirements) cause row rejection or error
- Exceeding 200 rows returns an error or truncation
- Invalid date format (not YYYY-MM-DD) fails schema validation
- All-null values for either measure prevents correlation computation
- Fewer than 2 rows may make correlation undefined or meaningless
