Scale Plan Required

The Fundup AI API

Build with our database of companies, funding events, and market intelligence.

Base URL https://fundup.ai/api/v1

Built for fresh signals, not bulk archives. Poll the API for newly funded companies as they happen. Access is capped at 500 records (50 per request), so it's for tracking what's new, not exporting the full history. For one-off bulk pulls, use Discover export in the dashboard.

Company Data

Detailed company profiles, funding history, key contacts, and market positioning.

Funding Events

Funding rounds, investment amounts, investor information, and market trends.

Advanced Search

Powerful filtering and search across companies, industries, and funding data.

Recommended: pair the API with webhooks

The API works best as a webhook + endpoint combination. A webhook notifies you the moment a company raises funding (no polling, no scanning) and you call the API on demand only for the companies that matter (contacts, full profile). Used this way you stay comfortably within rate limits, and it's the setup we recommend for tracking fresh signals. Read the webhooks guide →

Quick example

A single call to retrieve recently funded companies.

Available endpoints

GET /health Health check endpoint to verify API status GET /companies Retrieve a list of companies with advanced filtering and optimized server-side pagination. Uses hybrid database filtering for improved performance. GET /companies/{company_id} Get detailed information about a specific company. The contacts field follows the same availability rules as GET /companies/{id}/contacts: contacts are included during the 30-day fresh window after funding, or if you have previously revealed this company via the Fundup AI dashboard. GET /companies/{company_id}/tech-stack Get tech stack for a specific company. Returns 404 if tech stack is not available (e.g., website down, not yet analyzed). GET /companies/{company_id}/fundings Get all funding rounds for a specific company, including investor details. GET /companies/{company_id}/contacts Get key decision-maker contacts for a company. Contacts are returned under two conditions: (1) the company was funded within the last 30 days (free fresh window, same as the dashboard), or (2) you have previously revealed this company via the Fundup AI dashboard. The API never triggers Hunter lookups or consumes Reveal Credits, it reads from your existing reveal cache only. GET /companies/{company_id}/open-roles Get open job postings for a company with optional department/seniority filtering and pagination. GET /companies/{company_id}/highlights Get AI-extracted key business highlights for a company. GET /companies/{company_id}/news Get funding news articles associated with a company. GET /fundings Retrieve recent funding events with advanced filtering and optimized server-side pagination. Uses hybrid database filtering for improved performance. GET /filters Get available filter values for API endpoints (countries, industries, stages, company sizes, tech stack categories, technologies) GET /stats Get API usage statistics and real-time rate limit usage for the authenticated user. The rate_limits object includes per_minute, daily, monthly, monthly_export, daily_company_detail, and monthly_pagination, each with limit, used, remaining, and reset_unix. All keys (live and test) share the same account-wide budgets.
