Force-sorted by score; supports the full investor filter DSL to narrow the candidate pool. Offset pagination, capped at offset+limit ≤ 1000. ## OpenAPI ````yaml /mintlify/openapi.yaml get /api/data/investors/{id}/similar openapi: 3.1.0 info: title: Dealroom API version: '2026-07-06' description: >- REST API for the Dealroom platform — companies, funds, founders, investors, funding rounds, valuations, taxonomy, news, and aggregate analytics across all of them.
