How this service works
Sampling observations — Base-100 series + Keyed dataset comparison: Base-100 series + Keyed dataset comparison for supplied sampling observations records (sample_value, sample_weight). 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 analytical reports for the supplied rows: (1) a Base-100 indexed time series where values are rebased relative to a baseline period, and (2) a keyed dataset comparison aligning the primary and secondary datasets by row ID and group to highlight differences — all computed locally with no external data lookup.
Example use cases
Cohort index trend comparison
“I have weekly measurement readings split into two groups — treatment and control — with sample weights. Can you normalize both to a base-100 series starting from the first week and compare them side by side across the same row keys?”
Survey wave rebase analysis
“I ran two survey waves, each with up to 150 respondents tagged by date and group, and I need a base-100 reindex of the first wave plus a keyed comparison to the second wave using the sample_value field.”
Sales sampling panel benchmark
“I've got two panels of monthly sales samples, each row has a date, a group label, a sample value, and a weight — please produce a base-100 indexed series for the primary panel and a keyed dataset comparison against the benchmark panel.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-168?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a base-100 normalized time series and a cross-dataset keyed comparison in a single paid call, using your own supplied observation data (up to 200 rows) without requiring any external data lookup, prediction, or live enrichment. It is well-suited for researchers, analysts, or automated pipelines that already have structured sampling data with weights and need reproducible index and comparison analytics cheaply at $0.01 USDC per call.
Side effects
- Fewer than 1 row supplied — minItems constraint violation
- More than 200 rows submitted — maxItems constraint exceeded
- Invalid date format (not YYYY-MM-DD) on any row
- Missing required fields (row_id, dataset_group, date, sample_value, sample_weight) on any row
- sample_value or sample_weight outside the ±1,000,000,000,000 range
- Invalid field enum value (must be 'sample_value' or 'sample_weight')
- Payment of 0.01 USDC not completed — x402 payment required
