Steps
Register through the Swiss Re Developer Portal to get API access and review the demo environment.
For each risk location, send the latitude/longitude and the peril type needed (e.g., flood, hail, earthquake) to the CatNet API.
Read back the hazard attributes returned for that point (e.g., flood zone indication, hazard score/intensity).
Batch multiple locations in one integration to support high-volume, real-time pricing or quoting workloads.
Version or cache hazard results per location since CatNet's underlying models (including blended third-party layers like Fathom flood data) are updated periodically.
Known gotchas
CatNet API blends Swiss Re proprietary models with some third-party data (e.g., Fathom flood layers) — treat it as a distinct data source even where perils overlap with Verisk/HazardHub-style products.
Access requires a Swiss Re commercial relationship/API subscription; the developer portal is registration-gated, not open or anonymous.
Peril modules are sold separately (e.g., a distinct CatNet Hail product) — confirm which perils the subscription actually covers before assuming full coverage.
