The one rule, keep the owl

Free forever, in exchange for a visible credit.

Wherever you show OwlChart data, display a visible Powered by OwlChart link back to https://owlchart.com (the owl mark is welcome too). That is the whole deal: you get free live data, the owl gets seen. Every response carries a brand block with the exact text and link to use.

Notes

No API key needed. Endpoints are CORS-open so you can call them straight from a browser or an AI agent. Please cache on your side and avoid hammering (the data updates about once a minute). These endpoints are free and computed from public market data, so they cost nothing to run and stay free. Higher volume, webhooks, alerts and historical data will come as a paid tier later. Analytics only, never financial advice.
