B2B Food Intelligence API

The world's
dietary pulse

Anonymised, aggregated food intelligence derived from real dining behaviour. Allergen trends, intolerance prevalence, diet adoption, cuisine popularity — all via a single REST API.

Privacy by design

k-Anonymity enforced in every row

No personal data ever enters the Chez Vous database. Every ETL job applies strict k-anonymity (k ≥ 10): cohorts below the threshold are silently dropped before writing. Cohort sizes are bucketed in API responses — you know the signal is real without knowing who generated it.

  • ✓No PII — ever. Enforced at ETL, not just at query time.
  • ✓Cohort sizes bucketed: 10–49, 50–99, 100–499, 500+
  • ✓City-level data suppressed for small cohorts
  • ✓Read-only connection to source data — no write-back possible
