How this service works
Study recruitment — Daily sum series + Two-measure correlation: Daily sum series + Two-measure correlation for supplied study recruitment records (eligible_candidates, enrolled_candidates). 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 independent statistical reports: (1) a daily sum series aggregating the chosen measure (eligible_candidates or enrolled_candidates) by date, and (2) a correlation analysis between eligible_candidates and enrolled_candidates across all supplied rows. Results are computed locally from the submitted data with no external lookups.
Example use cases
Track enrollment rate trends over time
“I have four weeks of daily recruitment records for my clinical trial with eligible_candidates and enrolled_candidates per day per group — can you compute the daily sum series and tell me how correlated eligibility is with actual enrollment?”
Evaluate recruitment efficiency by course group
“Here's my study recruitment dataset with course groups alpha and beta over October — run the daily sum totals and a two-measure correlation between eligible and enrolled candidates so I can see which group converts better.”
Spot recruitment bottlenecks in academic program
“I've got 150 rows of daily recruitment data for our grad program with eligible_candidates and enrolled_candidates — can you produce the daily sum series focused on enrolled_candidates and also run the correlation between the two measures?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-education-09-141?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have up to 200 rows of study or course recruitment records with date, group, and dual numeric measures, and you need both a time-series daily aggregation and a correlation statistic in a single low-cost call. It is purpose-built for the eligible_candidates / enrolled_candidates schema and cheaper than general-purpose analytics APIs when your data fits this shape.
Side effects
- Missing required fields (row_id, date, eligible_candidates, enrolled_candidates) cause validation errors
- Input exceeding 200 rows is rejected
- Malformed date strings not matching YYYY-MM-DD pattern fail schema validation
- All-null values for a measure prevent correlation computation
- Payment of 0.01 USDC not confirmed blocks request processing
