How this service works
Commercial proposal comparisons — Adjacent row changes + Base-100 series: Adjacent row changes + Base-100 series for supplied commercial proposal comparisons records (quoted_amount, delivery_days). 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 for the supplied rows: (1) an adjacent row change report showing the numeric difference between each consecutive row for the selected field, and (2) a base-100 series report normalizing all row values relative to the chosen base index row. Both reports operate locally on the supplied data with no external lookups.
Example use cases
Vendor quote drift analysis
“I've got 15 commercial proposals from two suppliers over the past month — can you calculate the row-by-row changes in quoted_amount and also index them all to base 100 starting from row 0 so I can see which vendor's prices are drifting more?”
Delivery time trend indexing
“Can you run the adjacent row changes and base-100 series reports on delivery_days for these 20 proposal records across three vendor groups, using row index 0 as the baseline? I want to see how delivery commitments are shifting over time.”
Procurement bid comparison over rounds
“We received bids in multiple rounds from two companies — please analyze the quoted_amount field across all 50 rows with both the sequential delta report and the base-100 index starting at row 0, so I can compare how each company's pricing evolved round to round.”

Choose this endpoint when you have a structured list of commercial proposal records (with quoted amounts and/or delivery days) and need both a sequential row-change report and a base-100 indexed series in a single API call for under $0.01. Ideal for procurement analytics, vendor bid comparison, or any scenario requiring normalized trend analysis across proposal rows without external data dependencies.
Side effects
- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, date, company_group) cause validation errors
- base_index out of range (>= number of rows) causes indexing failure
- Null values in quoted_amount or delivery_days may produce null deltas in row change report
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Field enum value not 'quoted_amount' or 'delivery_days' causes rejection
