Ready for your first request
Set OPENSTOCK_API_KEY in your environment. Copy a request from a recipe and replace the example idempotency key with your own session key. The live demo uses its server-side credential; you can try it without entering yours.
Response examples are illustrative unless labelled as a synthetic fixture. They preserve the API envelope but do not represent current availability, measured performance or checkout verification. Example codes cannot be redeemed; example links omit live attribution. Use the URLs returned by your real request.
All recipes and examples are readable without JavaScript. Live execution is available in the demo.
