Summary\n- Use MiniMax's current token plan remains endpoint.\n- Prefer current interval and weekly remaining percentage fields when returned.\n- Keep the legacy count-based fallback for older responses.\n- Add parsing and endpoint tests.\n\n## Verification\n- passed.\n- Swift syntax check and a self-check against the live redacted response shape passed.\n- Full Swift tests could not run because this checkout is a Tuist project and no usable Tuist executable is currently installed.

📝 Walkthrough

Walkthrough

MiniMax now requests token-plan remains data. Quota parsing supports interval and weekly percentages, restrictive-window selection, reset duration calculation, and count-based fallback behavior. Tests update endpoint expectations and validate percentage-based output.

Changes

MiniMax token-plan support

Layer / File(s) Summary
Token-plan endpoint migration
Sources/Domain/Provider/MiniMax/MiniMaxRegion.swift, Tests/DomainTests/Provider/MiniMax/MiniMaxRegionTests.swift, Tests/InfrastructureTests/MiniMax/MiniMaxUsageProbeTests.swift
MiniMax region URLs and probe expectations now use /v1/token_plan/remains for China and international regions.
Percentage quota parsing
Sources/Infrastructure/MiniMax/MiniMaxUsageProbe.swift, Tests/InfrastructureTests/MiniMax/MiniMaxUsageProbeParsingTests.swift
Quota parsing decodes percentage and weekly fields, clamps values, selects the more restrictive window, calculates reset duration, and retains count-based fallback behavior. Tests cover zero count totals and a seven-day window.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to a7c09

Some MiniMax responses may show an incorrect usage percentage or interval when only the weekly remaining percentage is returned, especially at 100%; the change is otherwise localized and mergeable with explicit follow-up to cover this response shape.

MiniMax Coding Plan API model_remains current_weekly_remaining_percent current_interval_remaining_percent response

💡 Result:

The MiniMax Coding Plan API, typically accessed via the endpoint /v1/api/openplatform/coding_plan/remains (or similar, such as /v1/token_plan/remains), returns a JSON response containing quota information for various model buckets [1][2]. The response includes fields representing the percentage of remaining quota for specific time windows, rather than relying solely on request or token counts [3][1]. Key fields observed in the response include: current_interval_remaining_percent: An integer (0–100) representing the percentage of the current rolling interval (e.g., a 5-hour window) quota still available [4][5]. current_weekly_remaining_percent: An integer (0–100) representing the percentage of the weekly quota still available [4][5]. Technical Notes: Quota Model: MiniMax Token Plans use rolling interval and weekly usage windows [6]. For many models, particularly the general/coding bucket, the API may return zero for count-based fields (e.g., current_interval_usage_count) and instead provide these percentage fields to track usage [3][1]. Additional Fields: The API response often includes auxiliary data such as: current_interval_status and current_weekly_status: Observed values include 1 (partial) and 3 (full) [2][5]. interval_boost_permille and weekly_boost_permille: These reflect any active boost multipliers (e.g., 2000 representing a 2x multiplier) [2]. remains_time and weekly_remains_time: Epoch-based timestamps or durations indicating when the respective windows reset [3][4]. Note that these fields are not part of the standard OpenAI-compatible chat API response, but are specific to the MiniMax Open Platform quota management interface [1][7]. Developers should treat these as usage snapshots and verify documentation or wire-level observations, as MiniMax does not always provide a public schema for this specific administrative endpoint [1].

Handle payloads with only currentWeeklyRemainingPercent.

When currentIntervalRemainingPercent and legacyRemaining are absent, remaining becomes 0. A weekly value of 100 also selects the interval window because 100 < 100 is false. Select the available percentage, select the weekly window when it is the only percentage, and use percentage text when either direct percentage exists. Add fixtures for weekly values 98 and 100.

MiniMax accounts on a Token Plan only get OpenAI-compatible API keys.
The legacy coding-plan endpoint reports those as 0 of 0 requests, so
every model showed 0% available usage.

Switch the probe to GET /v1/token_plan/remains (same regional bases),
which answers for both plan generations:

- Prefer current_interval_remaining_percent and
  current_weekly_remaining_percent when present; Token Plan responses
  carry percentages while the count fields are 0.
- Emit one quota per window: the 5-hour interval keeps the existing
  modelSpecific identity, and the weekly window is a new
  "<model> Weekly" row with the weekly end time and span.
- Keep the count-based fallback (where usage_count is actually the
  remaining count) for older responses, and keep legacy models with a
  0 total at 0%.

Adapted from the unmerged #266, plus the per-window rows and tests.

Verified: full test suite (2,399 tests) green; live Token Plan key
returns 4 quotas (interval + weekly for "general" and "video").
