Real-time licensed feeds cost €4–10 per user per exchange. That math kills any indie-friendly price point. 15-minute delayed prices cover portfolio tracking, research dashboards, EOD analytics, and paper-trading sims — that's 99% of fintech apps you'd want to build. If you need tick-level execution data, you're our wrong fit. We'll tell you to your face — see the scope notes in our terms.

Frequently asked questions
Why is the data delayed by 15 minutes?
Real-time licensed feeds cost €4–10 per user per exchange — that math destroys any sub-€100 price point. 15-minute delayed data is the same data, just slightly behind, and it covers 99% of what indie apps actually do: portfolio tracking, research dashboards, end-of-day analytics, paper-trading simulators. If you need tick-level execution feeds we are upfront — we are not your fit. Use a broker API or a SIP feed.
Is there a free plan?
Yes. 800 requests per day, 8 per minute, no credit card. Enough to ship a side project, build a portfolio tracker MVP, or evaluate the API. We don't expire your free tier or demand a card after 30 days. We just expect you to upgrade when you start growing.
How do you compare to the budget incumbent at $29/mo?
Three things. (1) Our entry plan is €19/mo, not $29 — that is roughly 35% cheaper at typical FX. (2) We invoice in EUR with proper VAT IDs, which matters for European indie devs. (3) We don't paywall fundamentals or split history at the cheapest tier, because every portfolio tracker on earth needs them.
What exchanges do you cover?
70+ equity exchanges including NYSE, NASDAQ, LSE, Euronext (Paris, Amsterdam, Brussels, Lisbon, Dublin), Xetra, SIX, Borsa Italiana, OMX Stockholm/Helsinki/Copenhagen, ASX, TSX, TSE, HKEX, BSE, NSE, JSE, B3 — full matrix on the coverage page. ETFs and mutual funds globally. 30+ crypto exchanges via aggregated pairs.
Can I use this for a commercial product?
Yes. Every paid plan includes a commercial-use license for end-user-facing apps. There is no per-seat tax for the apps you build with our data. The only restriction: you cannot redistribute raw data or build a competing data API. The full carve-out is in the Terms.
Do you support European VAT, invoices, and SEPA?
Yes. We're a European company (Ireland), invoices include your VAT ID, and we charge EUR via Stripe with both card and SEPA Direct Debit on annual plans. Reverse charge applies for B2B EU customers outside Ireland.
What about historical data depth?
Default depth is 10 years on the Indie plan, 20+ years on Pro and Business. EOD daily for equities and ETFs back to 1990 for major US tickers, 2000+ for European, on a best-effort basis. Bulk historical exports (Parquet/CSV) are a Business-plan feature.
Can I self-host or run this on-prem?
Custom plan only. We can ship a containerized worker that calls our gateway from your VPC for compliance-sensitive workloads (banks, fund admins). Talk to us — we say yes to weird requests.
What happens if I exceed my rate limit?
Soft cap. We return a 429 with a Retry-After header. We don't auto-bill overage; we email you so you can decide to upgrade or back off. No surprise invoices.
How is this priced — by request, by symbol, by datapoint?
By request, full stop. One API call = one request. No data-point mathematics, no per-symbol bundles, no "streams" math. We hate that pricing model as much as you do.
