Summary

Fixes #425.

MiniMax redesigned the console: /console/usage and /console/plan are now Next.js pages loaded via next/dynamic(..., { ssr: false }). The server-rendered HTML never contains real quota numbers — userConfig is always null in __NEXT_DATA__ — regardless of whether the request carries a valid, authenticated cookie. Every cookie/HTML-scraping code path is therefore structurally unable to read usage data on the current site, so MiniMax fell through to probe_cli()'s hardcoded 0% "configured" stub whenever the cookie/HTML path failed (which is now always).

Fix

The coding-plan remains endpoint the HTML scraper already falls back to (/v1/api/openplatform/coding_plan/remains) also accepts a plain Authorization: Bearer <api_key> header, no cookie required, and returns the exact model_remains JSON shape the existing parser (coding_plan.rs) already handles and already has extensive test coverage for. This PR adds a Bearer-authenticated request to that same endpoint, tried first with an API key sourced from Settings (ctx.api_key) or MINIMAX_API_KEY, before falling back to the legacy group_id+api_key billing endpoint.

Also registers MiniMax in get_api_key_providers() so a plain API key can be entered via Settings / codexbar config set-api-key minimax — previously there was no supported way to configure just an API key; the provider only accepted a paired group_id+api_key via env vars or a local minimax-CLI-style config file that most Windows users don't have.

Verified

  • Confirmed via a working third-party scraper (Bearer-only, no cookies) that this exact endpoint currently returns live, correct quota data for the reporter's account.
  • Traced the Next.js webpack chunk for /console/usage and confirmed ssr:!1 on the dynamic import — the client-only rendering is intentional/structural, not a transient bug.
  • With an API key configured, codexbar diagnose -p minimax now returns source: "api" with real percentages and real resets_at timestamps instead of the fixed 0% stub.
  • All 37 existing providers::minimax tests still pass unmodified (the new code reuses the existing JSON parser); added a focused unit test for the new key-resolution helper.

Test plan

cargo test --manifest-path rust/Cargo.toml providers::minimax
cargo clippy --manifest-path rust/Cargo.toml --all-targets -- -D warnings
cargo fmt --manifest-path rust/Cargo.toml -- --check

All pass.

Summary by CodeRabbit

  • New Features
    • Added MiniMax API-key configuration support, including MINIMAX_API_KEY environment variable setup guidance.
    • MiniMax usage data can now be retrieved with API-key authentication.
    • Added fallback handling across supported MiniMax service endpoints.
    • Existing cookie- and configuration-based authentication remains supported.
    • Automatic and web-based usage retrieval now supports the same credential options.

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).

📝 Walkthrough

Walkthrough

MiniMax usage fetching now accepts API keys from FetchContext or MINIMAX_API_KEY, calls coding-plan remains endpoints with regional fallback, and preserves the existing cookie flow. Routing, tests, and provider configuration metadata were updated.

Changes

MiniMax usage flow

Layer / File(s) Summary
API-key remains fetching
rust/src/providers/minimax/mod.rs
The provider resolves and trims API keys, calls platform and www remains endpoints with Bearer authentication, handles responses, and converts JSON into usage results.
Context-aware routing and validation
rust/src/providers/minimax/mod.rs
Auto and Web sources pass FetchContext into API-key fetching. Tests cover credential precedence, blank values, trimming, and environment fallback.
MiniMax provider configuration
rust/src/settings/api_keys.rs
Provider metadata documents the optional API key, MINIMAX_API_KEY, quota retrieval, and the MiniMax dashboard URL.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 14056

MiniMax quota retrieval can temporarily fail when the primary host has a network error even though the fallback host is available. Retry the fallback host before reporting the fetch failure.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Retry the www remains URL after a network error.

Line 337 returns a ProviderError::Network from the platform host immediately. The existing cookie fallback retries the www host for network errors. A transient platform-host failure can therefore make API-key quota retrieval unavailable even when the www endpoint is reachable.

Proposed fix
-                Err(err @ ProviderError::Parse(_)) => {
+                Err(err @ (ProviderError::Parse(_) | ProviderError::Network(_))) => {
                     last_err = Some(err);
                 }

Thermo-nuclear review: REQUEST CHANGES (or close as superseded by #445)

  1. Medium - test mutates MINIMAX_API_KEY globally without synchronization. read_plain_api_key_prefers_ctx_then_env_then_none uses unsafe process-wide set_var/remove_var with no lock. Parallel Rust tests can observe or overwrite that state. This repo already has env_lock() patterns in Claude/Kimi tests. Use that pattern or make the resolver pure/testable without mutating the process environment.

  2. Medium - this grows an already 1,170-line provider module to roughly 1,298 lines. It does not cross the thermo threshold because it was already >1k, but Fix proxy, Claude auth, MiniMax, Ollama, and Alibaba issues #445 demonstrates the cleaner decomposition by moving the remains client into minimax/remains_api.rs. Prefer that structure rather than adding another ~128 lines to mod.rs.

  3. Medium - the new remains attempt discards every error. if let Ok(result) = fetch_remains_via_api_key(...) treats auth, network, and parse failures alike and silently falls into the legacy group-id path. For plain-key users this can replace the relevant failure with an unrelated fallback error. Preserve the meaningful error unless the specific failure is intentionally fallback-eligible.

This work is also functionally carried by #445. Avoid merging both implementations; closing this PR as superseded is simpler than maintaining two review paths.

[Bug]: MiniMax Global coding-plan page now redirects to /console/plan (client-rendered SPA) — scraper gets no data, falls back to 0%
