One API key per request, in the Authorization header.
Create keys on the API keys page of your dashboard. A new key is shown once; copy it then. Revoking a key stops it at once. Each workspace can have 5 active keys. All keys share the workspace’s allowance.
Send the key as a bearer token on every request to https://api.entropyapi.io:
curl 'https://api.entropyapi.io/v1/drugs/19711' \ -H "Authorization: Bearer $ENTROPY_API_KEY"The quickstart says where a key may live. If a key was shared anywhere, revoke it and create a new one. A request without a valid key answers 401; see errors and limits.
Keys belong to one workspace, and the workspace’s plan sets the allowance every key shares. Usage counts against the workspace, so the dashboard shows one total however many keys made the requests.
Send any request from the API Playground on your dashboard. Paste a key and the page holds it only until you leave; we never store it. Make a key named Playground on your API keys page for this and revoke it any time. Its requests count against that key’s workspace like any other.
