How this service works
Sampling observations — Base-100 series + Equal-width histogram: Base-100 series + Equal-width histogram 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 analytical reports: (1) a Base-100 indexed series where each observation's value is expressed relative to the chosen base row (set to 100), showing relative change over time; and (2) an equal-width histogram dividing the specified numeric field into the requested number of bins, with counts or weighted counts per bin. Both reports are computed locally from the supplied data with no external lookups.
Example use cases
Environmental monitoring baseline comparison
“I have 20 weekly soil-contamination readings with sample weights from our site — can you index them to a Base-100 series starting from week 1 and also bucket the values into 8 equal-width histogram bins so I can see the distribution?”
Survey response distribution analysis
“Here are 150 survey responses with numeric scores and respondent weights by demographic group. Give me a Base-100 trend series starting from row 0 and a 10-bin histogram of the score field so I can see how scores are spread out.”
Quality control sample trending
“We took 50 product weight samples across two production lines over the past month. Can you normalize them to a Base-100 series from the first sample date and show me a 6-bin histogram of the sample_weight field to check for anomalies?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-163?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have up to 200 weighted sampling observations and need both a Base-100 normalized trend series and an equal-width histogram in a single cheap ($0.01 USDC) API call. Prefer it over general-purpose statistics libraries when you want a hosted, payment-gated analytical computation with no setup, or when your agent workflow needs a stateless analytical step that returns structured distribution and indexing reports together. Not suitable for real-time data feeds, forecasting, or datasets larger than 200 rows.
Side effects
- More than 200 rows submitted — exceeds maximum row limit
- Invalid date format (must be YYYY-MM-DD) causes row rejection
- base_index out of range for the number of rows supplied
- bins parameter outside 1–30 range
- sample_value or sample_weight outside allowed numeric bounds (±1 trillion)
- All values null for chosen field — histogram cannot be computed
- Missing required row fields (row_id, dataset_group, date, sample_value, sample_weight)
- Payment failure via x402 protocol — endpoint returns 402 without processing
