Budget-Friendly Stock Market Data API for Startups and Developers

Published on 06/30/2025Marketing Opportunities

The post hits the nail on the head: many startups struggle with the high cost of essential tools, like a commercial stock data API. The founder needs this data to build their SaaS but can't afford the steep $2,000 monthly fee from established providers. The fact that they're willing to accept delayed data (15+ minutes) for a lower price highlights a clear market gap.

Opportunity: A budget-friendly financial data provider tailored for startups and indie hackers.

Product Form (SaaS): The product would be a financial data API specifically designed for early-stage companies.

  • Core Offering: Provide delayed (15-minute or EOD) stock market data, which is much cheaper to source than real-time data.
  • Pricing Model: A freemium model. A generous free tier allows developers to build and test their applications without any cost. Paid tiers would start at an accessible price point (e.g., $20-$50/month) for commercial use, with pricing that scales based on API call volume or additional features.
  • Key Differentiator: The business model is built on affordability and a "grow with your customers" ethos, directly contrasting with the high-cost, enterprise-first approach of competitors.

Expected Revenue: The business model focuses on volume rather than high individual contract value. The primary goal is to acquire a large base of developers on the free tier. Even a conservative conversion rate to paid plans could yield significant revenue. For example, if 500 startups pay an average of $50/month, that would generate $25,000 in Monthly Recurring Revenue (MRR). The model targets a large and growing market of developers entering the fintech space.

Hi all, I’m building a stock-focused SaaS tool and I’ve hit a wall when it comes to data APIs. I initially looked into Polygon.io, which looks solid but starts at $2,000/month for commercial

I think 15 minutes should be fine but if the price is right and it fits what I need I wouldn’t mind a little more for the time being until I see some traction and can invest more in it
