How this service works
Trade observations — Equal-width histogram + Two-measure correlation: Equal-width histogram + Two-measure correlation for supplied trade observations records (export_amount, import_amount). 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) an equal-width histogram breaking the selected field (export_amount or import_amount) into the specified number of bins with frequency counts per bin, and (2) a two-measure correlation report quantifying the statistical relationship between export_amount and import_amount across all supplied rows. Both reports are computed locally with no external data lookups.
Example use cases
Regional export distribution analysis
“I have 80 trade records across several regions with export_amount and import_amount values. Can you bucket the export_amount into 8 equal-width bins and also tell me how correlated exports and imports are across all those records?”
Import volume spread check for quarterly data
“Here are 200 rows of quarterly trade observations. Please run an equal-width histogram on import_amount using 5 bins and compute the two-measure correlation between export_amount and import_amount so I can see if they track each other.”
Trade balance correlation for policy briefing
“I need a quick statistical summary for a policy briefing — I've got 60 trade observation rows covering different dates and regions. Run a 10-bin histogram on export_amount and show me the correlation coefficient between exports and imports.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-economics-06-171?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a histogram distribution report and a pairwise correlation between export and import trade amounts in a single $0.01 call, without needing live data lookups, predictions, or external enrichment. Ideal for offline or batch analytical workflows on pre-collected trade observation datasets of up to 200 rows.
Side effects
- Fewer than 1 row supplied — validation error
- More than 200 rows supplied — exceeds maximum, request rejected
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Bins parameter outside 1–30 range — rejected by schema
- Null values in both numeric fields for all rows — correlation cannot be computed
- Field enum value not matching 'export_amount' or 'import_amount' — validation error
- Missing required row_id field — schema validation failure
- Payment not completed (x402) — endpoint returns 402 Payment Required
