Build on the Venture Decision OS.

Startup Screener exposes a REST API surface for screening, Scout, evidence graph, decisions, exports, and the 14-module Venture OS. Provider-neutral records are live now; external adapters stay governed by source license, scope, entitlement, and audit metadata.

Venture Decision OSVenture OS previewOpenAPI docs

Evidence contract

Every claim, score, and signal includes source ID, confidence score, permission scope, model origin, and captured timestamp.

Session authentication

API access uses HTTP-only session cookies. Call /auth/login to obtain a session, then include credentials on subsequent requests.

Webhook-ready governance

Marketplace records define future webhook and adapter scopes before third-party systems receive operational events.

Rate limiting

Quick screen uploads are rate-limited per IP. Authenticated endpoints have higher throughput limits per organization.

Provider-neutral imports

Venture OS modules accept governed CSV/JSON records now, while licensed CRM and data-provider adapters remain pluggable through scoped marketplace records.

Venture OS API rules

Production contracts are live, but data access remains governed.

13 OS paths

All authenticated Venture OS endpoints require the same HttpOnly session cookie flow as the workspace.

Every factual object must carry source type, captured timestamp, permission scope, origin, attribution, freshness, and confidence.

Tenant isolation is mandatory: users only see authorized organization, cohort, reviewer, or participant scope.

Valuation and predictive outputs must expose confidence, sample size, calibration status, limitations, and no-investment-advice wording.

External provider, CRM, webhook, and marketplace integrations remain governed adapter records until license terms and scopes are configured.
