Authentication
Include your API key in the x-api-key header. Do not use Bearer token format. The API uses a custom header, not the standard Authorization header. Keep your key in a server-side environment variable or secret store. Never include it in browser or mobile client code, public repositories or logs. Replace <API_VERSION> with the dated version shown on the endpoint page. Use Content-Type: application/json when sending a JSON body.
x-api-key: <MYMOLECULES_API_KEY>
mymolecules-api-version: <API_VERSION>
Content-Type: application/json
