Top fintech startups

The shortest end-to-end query you can run against the Dealroom API. It authenticates with your API key, fetches the 10 most-funded companies tagged fintech, and prints them. Adapt it by swapping the industry, sort key, or limit. The same primitives apply across the API. The Dealroom API filters industries by numeric tag ID. Each example first looks up the current ID for Fintech, then uses it to query Dealroom-classified startups through /data/companies.

To reuse this recipe for another industry, change the value of q in the /reference/filters/taxonomy_id/values request. The response includes the accepted numeric IDs.

Prerequisites

Complete the Quickstart to create an API key and make your first request.
DEALROOM_CLIENT_ID and DEALROOM_CLIENT_SECRET exported as environment variables.
jq for the cURL and Command Prompt snippets (token extraction and output formatting). The PowerShell, Node.js, and Python variants don’t require it.

Where to go from here

Swap the tag ID for any other industry — use /reference/filters/taxonomy_id/values?type=industry to discover tag IDs. See the Filters reference for the full operator list.
Combine filters with and() / or() — see Filtering.
Compute totals or rankings server-side instead of paging — see Aggregates.
