Sedis PartnerAPI v2 — Developer Guide

The Sedis Partner API v2 is a REST + JSON API giving programmatic access to two Sedis products: Bolagsanalys (listed-company valuation data) and Fastighetsbenchmark (real-estate benchmarking data — your property units, collections, comparison zones, time-series, and geometry). v2 is designed to be machine- and LLM-friendly: a bare JSON envelope, camelCase fields, named query filters, sparse fieldsets, RFC 7807 errors, and X-Api-Key authentication.

API version: 2.0.0 · Base URL: https://api.sedis.se/v2 · OpenAPI spec: https://api.sedis.se/openapi/v2.json

Existing v1 partners: your v1 integration continues to work, unchanged. v2 is a brand-new, parallel surface with no v1 deprecation date — adopt it when you are ready (see Migrating from v1).
