docs(providers): add the SCX.ai provider page

[bhuvan2134686]

Adds the provider page for the scx-ai route, which BerriAI/litellm#34752 registers as a JSON-configured OpenAI-compatible provider

The page covers the two chat models on the route, scx-ai/GLM-5.2 and scx-ai/Qwen3.8-Max, with their context and output limits, and shows SDK plus proxy usage for streaming, function calling, structured output and image input. Every capability listed was checked against the live endpoint rather than taken from a model listing

It also records two behaviours a caller would otherwise hit by surprise: max_completion_tokens is sent upstream as max_tokens, and temperature is accepted in [0.0, 2.0) with 2.0 itself rejected, so LiteLLM clamps to 1.99

This is also a prerequisite for the main PR. The documentation and code-quality jobs there run tests/documentation_tests/test_env_keys.py, which checks this repo out and fails on SCX_API_KEY being read under ./litellm but mentioned nowhere in the docs. Verified locally that the page clears the gate:

$ python ./tests/documentation_tests/test_env_keys.py
Every environment variable read under ./litellm is documented

I work at SCX.ai

Note

Low Risk
Documentation-only: new provider page, sidebar entry, and env-var listings. No runtime or security logic.

Overview
Adds a provider page for the scx-ai/ route covering scx-ai/GLM-5.2 and scx-ai/Qwen3.8-Max, with SDK and proxy examples for streaming, tools, JSON schema, and vision.

Documents SCX_API_KEY / SCX_API_BASE (also listed in proxy env-var reference) and two upstream quirks: max_completion_tokens is sent as max_tokens, and temperature is clamped to 1.99 because SCX rejects 2.0.

Links the page from the providers sidebar.

This is the docs half of BerriAI/litellm#34752, and it is currently what gates that PR from going green. The code-quality and documentation jobs on #34752 check out litellm-docs main into docs/my-website, so test_env_keys.py cannot see the SCX.ai page until this merges, and it fails on SCX_API_KEY being undocumented.

Latest push adds SCX_API_KEY and SCX_API_BASE to the environment variables reference table in docs/proxy/config_settings.md, so the credentials appear there alongside the other providers rather than only on the provider page. Verified locally by running tests/documentation_tests/test_env_keys.py from the litellm repo with docs/my-website pointed at this branch; it reports every environment variable documented, and the same run against main reproduces the failure.

Could someone take a look when there is a chance. Happy to adjust anything on the page.

@mubashir1osmani @ryan-crabbe-berri @tin-berri bumping this one, it is small and it is a hard gate on another PR. Three files, 238 additions, no deletions, a single provider page plus the sidebar and index entries.

BerriAI/litellm#34752 cannot go green until this merges. .github/workflows/test-code-quality.yml in the code repo checks out BerriAI/litellm-docs into docs/my-website with no ref:, so it always reads litellm-docs main, and tests/documentation_tests/test_env_keys.py then fails on SCX_API_KEY because the page documenting it only exists on this branch. That makes the code-quality and documentation jobs on #34752 fail for a reason no commit on #34752 can fix. Everything else there is green, 77 of 79 checks pass.

I cannot request a reviewer from a fork, the API returns 404, so this comment is the only ping available. Happy to rebase or trim if anything here needs changing.
