I run claude.ai-platform.space — a SaaS proxy that gives developers metered access to Claude through pooled subscriptions instead of per-token billing. This blog is what I learn shipping it.
I run Claude API Platform — a SaaS that gives developers access to Claude through a pool of subscription accounts (Max plans), rather than the official per-token API.
Why bother building yet another proxy? Because at high request volumes, subscription beats metered billing by 5–7×. We pass that saving to clients while keeping the experience identical to the Anthropic SDK.
This blog documents what I learn running it: how the OAuth pool rotates, what prompt caching actually does to bills, when Sonnet beats Opus, where things broke at 3 AM.
