1. Is there a sandbox environment available for testing?
Yes, we have a free API sandbox environment that you can try out. Refer Sandbox Environment for more details. The sandbox environment gives you access to the Cybersecurity feed and all the companies, funding rounds, acquisitions, investors, sectors (Practice Area/Feed/Business Models) under it.
2. Is there a separate token for sandbox and production environments?
No, you can use the same token for both the environments. You only need to change the endpoint URLs.
