How this service works
Market survey observations — String normalisation + Two-measure correlation: String normalisation + Two-measure correlation for supplied market survey observations records (respondent_count, 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
Two analytical reports: (1) a string normalisation report covering the company_group and related string fields across submitted rows, and (2) a Pearson or equivalent correlation report between respondent_count and sample_weight, computed locally without any external lookup or live data.
Example use cases
Survey panel quality check
“I have 50 rows of market survey data with company groups, dates, respondent counts, and sample weights — can you normalise the string fields and tell me if there's a meaningful correlation between respondent count and sample weight?”
Cross-group survey comparison
“We ran a brand survey across group-a and group-b over Q4 2026 — can you clean up the group label strings and compute the correlation between how many respondents we had versus their sample weights for all 120 rows?”
Weighted response analysis
“Before I present my survey findings, can you normalise the company group names and run a two-measure correlation between respondent_count and sample_weight on my 80 observation rows so I can check if weighting is aligned with sample size?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-company-06-033?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have market survey tabular data and need both string field normalisation and a statistical correlation between respondent count and sample weight in a single low-cost call. Ideal for preprocessing survey exports before reporting, validating weighting schemes, or quickly checking measure relationships without setting up a local analytics environment. At $0.01 USDC for two reports on up to 200 rows, it is cost-effective for routine survey QA pipelines.
Side effects
- Exceeds 200 rows limit — request rejected
- Missing required fields (row_id, date, respondent_count, sample_weight) — validation error
- Null values in both numeric measures preventing correlation computation
- Invalid date format not matching YYYY-MM-DD pattern
- Empty rows array — minimum 1 row required
