 The SDK supports providing provider options for multiple providers simultaneously.
 The value is only checked for valid JSON at startup and will fail at runtime if it contains invalid options.
 
+#### PROVIDER_USER_AGENT
+
+If BASE_URL, MODEL, and PROVIDER_API_KEY are not set (Default Zen), a custom header is set:
+
+```text
+User-Agent: opencode/version
+```
+
+This header increases the rate limit for request for the free OpenCode Zen endpoint.
+
+To disable this without changing one of the above variables, you can set an empty value:
+
+```text
+PROVIDER_USER_AGENT=
+```
+
+Otherwise, you can set a custom User-Agent (prefix) to anything you choose:
+
+```text
+PROVIDER_USER_AGENT='my-app/1.0'
