How this service works
Event attendance - Base-100 series: Base-100 series for Event attendance. Up to 200 supplied typed records. Local numeric and data-quality processing; no external enrichment or forecasting. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded base-100 series deliverable.
Output
Returns a base-100 indexed series derived from the supplied event attendance or registration data, where each row's value is expressed relative to the selected base row (base_index). Output includes normalized index values per row, enabling direct comparison of relative trends across event types and dates without external enrichment or forecasting.
Example use cases
Conference attendance trend indexing
“I have 50 rows of weekly conference attendance data with dates, event types, and attendee counts from Jan to Dec 2023. Can you generate a base-100 index series on the 'attendees' field, using row 0 as the base, so I can see how attendance grew relative to the first event?”
Comparing webinar vs in-person registration growth
“I've got registration numbers for both webinar and in-person events across 2024. Can you normalize the 'registrations' field into a base-100 index starting from row 0 so I can compare how each event type's sign-ups grew on the same scale?”
Quarterly event performance benchmarking
“I need to benchmark event performance across quarters — I have 80 rows of event data with dates, event types, and both registrations and attendee counts. Please index the 'registrations' field to base-100 from row 0 so I can measure relative growth each quarter.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-sector-analytics-event-attendance-index?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have raw event attendance or registration data (up to 200 rows) and need to normalize it to a base-100 indexed series for trend comparison — particularly when you want local, deterministic numeric processing with no external dependencies. Ideal for dashboards, reports, or agent workflows that need to compare attendance trajectories across different event types on a common scale without forecasting or enrichment.
Side effects
- Missing required fields (row_id, event_type, date, registrations, attendees) cause validation errors
- base_index out of range (exceeds number of rows supplied) returns an error
- More than 200 rows submitted exceeds the maxItems limit and is rejected
- Null values in the selected field (registrations or attendees) at the base row may cause division errors or undefined output
- Malformed date strings not matching YYYY-MM-DD pattern are rejected
