Authentication uses Auth0 (Bearer JWT or OAuth2 client_credentials). All endpoints are versioned via the `API-Version` header (Stripe-style date-based versioning). contact: name: Dealroom API support email: support@dealroom.co url: https://dealroom.co termsOfService: https://dealroom.co/terms license: name: Proprietary — Dealroom commercial license url: https://dealroom.co/terms servers: - url: https://api-next.dealroom.co description: Production - url: https://api-next.beta.dealroom.co description: Beta - url: https://api-next.staging.dealroom.dev description: Staging security: - bearerAuth: [] - oauth2: [] tags: - name: Discovery description: API root discovery and functional namespaces. - name: Entities description: >- Companies, investors, people, universities, and other organisations. Filter, sort, and paginate the unified entity index. The term `investor` refers to the investment firm; `fund` refers to the capital vehicle it raises. - name: Companies description: >- Company profiles — the `organization_subtype = company` subset of entities (excludes investors, universities, and gov/NGOs). Same response shape as the entity index, scoped to companies. - name: Universities description: >- University profiles — the `organization_subtype = university` subset of entities. The `university` sub-object carries alumni metrics. - name: Government & NGO description: >- Government bodies and NGOs — the `organization_subtype = gov_ngo` subset of entities. - name: Transactions description: >- Funding rounds, equity events, debt, grants, exits, and other company-level financial events. - name: Valuations description: Company valuation history by year and month. - name: Investors description: >- Investor profiles (VCs, corporates, angels, family offices, governments). Subset of entities where `is_investor = true`. An investor is the firm that makes investments; the capital vehicles it raises are funds available via `/investors/{id}/funds`. - name: Funds description: >- Funds — the capital vehicles investor firms raise (e.g. "Fund III", $200M, 2024). Browse/filter by manager, type, size, and vintage; each fund links to its manager (GP). Fund size (`amount`) converts to the requested `?currency=` (default USD); `amount_source` carries the original native-currency amount. - name: People description: >- Person profiles (founders, executives, angels, and others). Subset of entities where `entity_type = 'person'`. Same response shape as founders, with company associations, education, and backgrounds. - name: Founders description: >- Founder profiles with company associations and education history. Subset of entities where `is_founder = true`. - name: News description: Curated news articles about companies, funds, deals, sectors, and events. - name: Jobs description: Active job openings posted by companies, with hiring-trend signals. - name: Aggregate description: >- Composable single- and multi-metric aggregations across companies, funding rounds, valuations, founders, and investors. - name: Funding Analytics description: 'Purpose-built analytics: 2D heatmaps, round transitions, capital funnels.' - name: Timeseries description: Yearly entity metrics (employees, revenue, valuation). - name: Matching description: >- Investor matching tool: ranked investor recommendations for a given deal profile. - name: Filters description: >- Filter registry discovery and value lookup. Use `/api/reference/filters` to discover available filters per scope and `/api/reference/filters/:key/values` to look up valid values. - name: Account description: User profile, authentication introspection, and account settings. - name: API Keys description: >- Self-service API key management. Programmatic (M2M) keys for server-side and Application (PKCE) keys for browser SPAs. - name: Teams description: Team membership and invitation management. - name: Usage description: Request-count usage analytics per API key for billing and introspection. - name: Metrics description: >- Service observability metrics (OpenTelemetry configuration and runtime counters). - name: Health description: Liveness probe (public, unauthenticated). - name: Search description: >- Cross-resource fuzzy search across companies, investors, people, universities, and government & NGO bodies. - name: Ecosystems description: >- Curated entity collections that can be filtered, navigated, and compared.
