Insurance underwriting

Use Overwatch risk intelligence to inform marine insurance underwriting decisions. These endpoints combine vessel risk scores, PSC inspection history, dark fleet activity, and sanctions exposure into actuarial-grade outputs.

`GET` `/api/v1/insurance/claims-prediction`

Requires API key.

Predict the claims probability for a vessel based on its risk profile, age, inspection history, and dark fleet involvement. Returns a probability score and the contributing risk factors. Parameters

`GET` `/api/v1/insurance/premium-adjustment`

Requires API key.

Calculate a premium adjustment factor for a vessel. The factor is based on the vessel’s risk score, sanctions exposure, PSC inspection history, and dark fleet activity. A factor above 1.0 suggests a premium increase; below 1.0 suggests a discount. Parameters
