See your WanAPIs balance in Claude Code and CC Switch

Setup steps

1. 1

   Check it once from the terminal

   Replace sk-xxx with your key and run the command below. balance is what you have left; hard_limit_usd is your total credit so far (used + remaining).

   Terminal

   curl https://api.wanapis.com/v1/dashboard/billing/subscription \
     -H "Authorization: Bearer sk-xxx"
   
   # Example response
   {"object":"billing_subscription","has_payment_method":true,"soft_limit_usd":125.5,"hard_limit_usd":125.5,"system_hard_limit_usd":125.5,"access_until":0,"balance":23.8}

   Claude Code: install a status bar plugin

   The open-source claude-statusbar plugin (GitHub: leeguooooo/claude-code-usage-bar, MIT) uses the ANTHROPIC_BASE_URL and key you already set for Claude Code, finds the balance endpoint on its own and shows your remaining balance in the status bar, refreshing every 5 minutes. No extra configuration — restart Claude Code after installing.

   Install (needs Python; uv tool install or pipx install also work)

   pip install claude-statusbar
   cs --setup

   CC Switch: paste a script into Usage Query

   Works for both Claude Code and Codex providers. Hover over your WanAPIs provider card, click Usage Query (📊 icon) → turn on Enable usage query → choose the Custom template → paste the script below → click Test script, and save once you see your balance. {{apiKey}} is filled in with the key from that provider automatically. An auto query interval of 5 minutes is a good default.

   CC Switch → Usage Query → Custom

   })
