# Fenris API Documentation

> Fenris provides insurance prefill APIs covering Auto Insurance, Property, Commercial Insights, Customer Insights, Analytics, Lead Score, and Scores. The API suite returns pre-filled applicant data and risk scores to streamline quoting and underwriting workflows. All endpoints require OAuth2 bearer token authentication.

Fenris APIs are consumed by carriers and MGAs to reduce form-fill friction, validate risk data, and improve conversion rates. The documentation below covers authentication setup, all available endpoints with request/response schemas, and the raw OpenAPI definition for direct machine consumption.
