What quality standards do you require?

We only accept data feeds that are professional-grade. Professional-grade means:

  • Accurate, precise and consistent; free of gaps and errors.
  • Perfectly documented with rich metadata and solid methodology.
  • Always up-to-date and reliable.
  • Supported by genuine domain experts.

Exceptional data feeds do not have to be big. A data feed with 100 error-free, well-documented, reliably up-to-date time-series data is way better than a data feed with 10,000 time-series that falls short on any of these measures.
