+Authentication
+--------------
+
+All requests to the Modeling API must include authentication credentials.
+
+API access tokens are applied to your requests to protect sensitive PII and are compliant with common privacy and security standards.
+
+A valid token must be included as part of the HTTP ``Authorization`` header, using the `bearer` HTTP authorization scheme. The value of the header will be ``Bearer <token>``, where you replace <token> with a valid token. Valid tokens will be provided to established customers of the API. It is planned to add the ability to rotate tokens and set expiration dates in future releases.

+.. code-block::
+
+  Authorization: Bearer <token>
+
+
+Here is an example using cURL:
+
+.. code-block:: shell
+
+  curl -v 'https://api.radiantlabs.co/v1/timelines' \
+    -H 'Content-Type: application/json' \
+    -H 'Authorization: Bearer <token>' \
+    --data-raw '{"addressFull":"501 RANDALL RD, BALLSTON SPA, NY 12020"}' \
