Stable, affordable, ready-to-use AI API relay
CC = Claude Code · Sub = Substitute · Your Claude subscription alternative
AI API relay built for global developers. No VPN needed, works anywhere.
Official enterprise-grade channels only. We reject reverse-engineered or degraded models. Built-in one-click key testing lets you verify model authenticity — a CCSub exclusive.
One API key for all models. Works with Claude Code, Codex, OpenClaw, Cursor, and 8+ tools out of the box. CC-Switch configures everything in seconds.
1 RMB = 1 USD quota — roughly 30% of direct API cost. Enterprise bulk purchasing passes savings directly to developers. Credits never expire.
Multi-route intelligent routing with instant failover. Every API call is traceable; full cost breakdown available at a glance.
Call image generation with the same OpenAI Images API you already use. Model names like gpt-image-1 / dall-e-3 work out of the box — just create a key in the image group. Billed per image from your balance, credits never expire.

Top up ¥100 and get $100 in quota. At ~7.2× official exchange rate, that's roughly 30% of direct API cost.
Each API call is billed by actual token usage, matching official pricing. Pay only for what you use. Credits never expire.
Monthly plans include a fixed daily quota (e.g. $50/day on Standard), as low as ¥0.31/USD. Quota refreshes daily and stacks with pay-as-you-go balance.
Spending automatically unlocks VIP tiers with lower multipliers. VIP8 gets a 0.88× rate — the more you use, the less you pay.
One Claude Sonnet 4.6 coding exchange (5,000 input + 2,000 output tokens):
Input: 5,000 ÷ 1,000,000 × $3 = $0.015
Output: 2,000 ÷ 1,000,000 × $15 = $0.030
