fix(minimax): fetch real quota via Bearer API key - #448
Merged
Conversation
MiniMax redesigned the console: /console/usage and /console/plan are now client-rendered Next.js pages loaded with `ssr:false`, so the server never emits real numbers in the initial HTML — not even with a valid, authenticated cookie. Every cookie/HTML-scraping path is structurally unable to read this data, so MiniMax usage fell through to the always-0% "configured" stub whenever cookie scraping failed. The coding-plan `remains` endpoint the HTML scraper already falls back to also accepts a plain `Authorization: Bearer <api_key>` with no cookie at all, and returns the exact `model_remains` JSON shape the existing parser (coding_plan.rs) already understands. Add a Bearer-authenticated path that tries this endpoint first, using an API key from Settings or `MINIMAX_API_KEY`, before falling back to the legacy group_id+api_key billing endpoint. Also register MiniMax in `get_api_key_providers()` so the API key can be entered through Settings/`config set-api-key` like other providers — previously there was no supported way to configure just an API key (only a paired group_id+api_key via env vars or a local `minimax`-CLI-style config file).

📝 WalkthroughWalkthroughMiniMax now resolves plain API keys from fetch context or environment, queries coding-plan remains endpoints with Bearer authentication, and falls back to legacy group-ID billing only after parse failures. ChangesMiniMax quota retrieval
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to MiniMax quota retrieval can report misleading zero usage when an API key is invalid or the service is unavailable, and some valid alternate-endpoint responses may never be tried. These issues should be corrected before merge. Sequence Diagram(s)sequenceDiagram

Do not convert remains API failures into a successful CLI result.
In SourceMode::Auto, line 1048 discards AuthRequired and Network errors from the new plain-key remains request. probe_cli then returns a configured 0% snapshot when MINIMAX_API_KEY exists. An invalid key or service outage is therefore reported as successful usage data.
Preserve errors after a plain API key was attempted. Use the CLI fallback only when no plain key was available or another fallback succeeds.

Keep conversion parse failures inside the URL fallback loop.
When to_usage_snapshot returns ProviderError::Parse for a parsed but empty snapshot, ? exits fetch_remains_via_api_key before it tries the www remains endpoint. Handle this error like the existing Err(ProviderError::Parse(_)) branch so the loop continues.

Maintainer replacement for #431 because the original head is in an external fork. Includes the reviewed MiniMax Bearer remains fix, isolates it in a provider-local module, preserves auth/transport failures, and removes process-global env mutation from tests.\r\n\r\nSupersedes #431.\r\n
