Query coding-plan / agent-plan usage for Volcengine Ark via the
control-plane OpenAPI (open.volcengineapi.com), which requires
account-level AccessKey signing rather than the inference API key.
- Implement Volcengine Signature V4 (an AWS SigV4 variant: fixed
canonical header order, "HMAC-SHA256" algorithm without the AWS4
prefix, scope ending in "request", service "ark") in
services/coding_plan.rs
- Auto-detect the plan by probing GetAFPUsage (Agent Plan, AFP
five-hour/weekly/monthly quotas) first, falling back to
GetCodingPlanUsage (Coding Plan, session/weekly/monthly percentages);
a single credential covers whichever plan the account holds
- Parse the real response shape: the window label lives in the `Level`
field; guard ResetTimestamp <= 0 (session returns -1)
- Store account-level credentials on UsageScript (accessKeyId /
secretAccessKey), threaded through both the test command and the
TOKEN_PLAN auto-refresh path
- Add an independent AK/SK input block with a detailed hint pointing to
the Volcengine console -> API Access Keys
- Add the `monthly` tier label (frontend TIER_I18N_KEYS + tray
TIER_LABEL_GROUPS + subscription service)
- Sync zh / en / ja / zh-TW locales and the usage-query docs
Add a new "Token Plan" template type in the usage query panel that
natively queries quota/usage from Chinese coding plan providers
(Kimi For Coding, Zhipu GLM, MiniMax) without requiring custom scripts.
- Rust backend: new coding_plan service with provider-specific API
queries (Kimi /v1/usages, Zhipu /api/monitor/usage/quota/limit,
MiniMax /coding_plan/remains) normalized into UsageResult
- Frontend: Token Plan template in UsageScriptModal with auto-detection
of provider based on ANTHROPIC_BASE_URL pattern matching
- Follows the same pattern as GitHub Copilot template (dedicated API
path in queryProviderUsage, no JS script needed)
