ACTIVITY reports how often a respondent (identified by token) has been seen across the Research Defender ecosystem in a time window. It is hosted on https://prod.resdefio.com and authenticates with an x-api-key header.

Core Functionality

  • Cross-platform respondent activity tracking
  • Statistical analysis of survey participation patterns
  • Professional survey taker identification through behavioral metrics
  • Ecosystem-wide intelligence spanning multiple research platforms
  • Configurable time-range analysis (1, 3, 8, 12, 24, 168, or 730 hours)
  • Advanced statistical modeling including averages, medians, and standard deviations

Key Features

  • Ecosystem Intelligence: Leverages data from millions of respondents across multiple platforms
  • Statistical Analysis: Provides count, average, ratio, median, and standard deviation metrics
  • Configurable Time Windows: Allows analysis across different time periods
