Const

Constants for the Proxy app.

smarter.apps.proxy.const.BUILTIN_PROXY_PATH = '/Users/mcdaniel/Desktop/gh/smarter-sh/smarter/smarter/smarter/apps/proxy/data/proxy': The built-in Proxy manifests, which manage.py add_builtin_proxies applies.

smarter.apps.proxy.const.CREDENTIAL_HEADERS = ('authorization', 'x-api-key', 'x-goog-api-key', 'api-key')

The request headers in which callers may send their Smarter API key, in the order in which.

they are checked. Each is how a popular SDK sends its API key, so that callers can use the provider’s own SDK, with a Smarter API key:

Authorization: Bearer <key>: OpenAI, and OpenAI-compatible SDKs. Authorization: Token <key>, as for the rest of the Smarter API, also works.
x-api-key: Anthropic.
x-goog-api-key: Google Gemini.
api-key: Azure OpenAI.

None of them is forwarded to the provider.

smarter.apps.proxy.const.DEFAULT_TIMEOUT = 120

Seconds.

LLM responses, especially long completions, can be slow.

hop-by-hop headers, the caller’s.

credentials, Smarter’s cookies, and the caller’s address. accept-encoding is dropped so that the provider’s response is decoded before it is returned, which lets Smarter read its token usage.
