How to Use the Startup Signals API

A complete guide to integrating GitDealFlow's free startup momentum API.

Getting started

The API is free and requires no authentication. Start with GET /api/signals.json for the full dataset.

Available endpoints

JSON API, CSV export, OpenAPI spec, MCP server, A2A endpoint, NLWeb, pick the surface that fits your stack.

Rate limits and fair use

No hard rate limits but please cache responses. The dataset updates weekly so hourly polling is overkill.
