How this service works
Procurement research — Adjacent row changes + Secondary-measure weighted mean: Adjacent row changes + Secondary-measure weighted mean for supplied procurement research records (quoted_amount, quoted_units). 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) adjacent row changes showing the delta in the selected field (quoted_amount or quoted_units) between each consecutive record, and (2) a secondary-measure weighted mean of the selected field using the other measure as weights — all computed locally against the supplied dataset without any external lookup.
Example use cases
Vendor quote drift analysis
“I've got a list of procurement records from our last 6 months of vendor bids — can you calculate the change in quoted_amount between each consecutive row and also give me the weighted mean of quoted_amount using quoted_units as weights? I want to see how quotes have shifted over time.”
Supplier cost benchmarking
“Here are 150 procurement entries across two company groups with dates, quoted amounts, and quoted units — run the adjacent row changes report and the secondary-measure weighted mean on quoted_amount so I can benchmark how each supplier's pricing evolves row by row.”
Purchase order trend summary
“Can you analyze these purchase order quotes? I need two things: the step-by-step differences between each row's quoted_amount and a weighted average price where quoted_units is the weight — the dataset has about 80 rows with row IDs, company groups, and dates.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-company-11-159?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have a batch of procurement records (up to 200 rows) and need both a sequential row-difference report and a unit-weighted average price in a single call for $0.01 USDC. Ideal for offline/batch procurement analytics where no live market data or external lookups are needed, and where you want deterministic, reproducible computation on your own supplied data.
Side effects
- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, company_group, date, quoted_amount, quoted_units) cause validation errors
- Invalid date format (not YYYY-MM-DD) triggers schema rejection
- Null values in quoted_amount or quoted_units may affect weighted mean computation
- Non-numeric values in amount or units fields cause parsing errors
