Quickstart
Make your first Marvin2 API calls in a few minutes.
Before you start
You need an organization API key. Production keys start with r6-. Test keys start with r6-test-. Send the full key on every request:
x-api-key: r6-yourKeyId.yourSecret
Test keys charge a separate Marvin2 quota. With a test key you can also send X-R6-Fixture: default to receive a canned classification without consuming quota — see Environments.
