Available Datasets
Bitcoin price (real-time and historical), Irish property prices, global M2 liquidity, central bank balance sheets, national debt by country, salary purchasing power, and chart catalog. All endpoints return JSON with documented schemas.
Rate Limits
Public endpoints: 60 requests per minute, 10,000 per day per IP. Authenticated endpoints (with optional API key): 600 per minute, 100,000 per day. Generous enough for personal use, dashboards, and research.
Embeddable Charts
Beyond the JSON API, every chart can be embedded as a responsive iframe. Interactive embed configurator available on the API page.
Frequently Asked Questions
Do I need an API key?
No. Public endpoints work without authentication. Optional API keys raise your rate limits and unlock additional endpoints.
Is the API free?
Yes. The public tier is free forever for non-commercial use. Commercial users with high-volume needs can request a higher-tier key by contacting hnewell@sharpdraw.org.
Can I use the data commercially?
Yes, with attribution. Charts and data are licensed CC-BY 4.0 — credit Irish Hodler with a link to irishhodler.com.
