A 90% discount on
Claudeand Codex API access should be an immediate red flag, yet the resellers keep multiplying and the deals keep getting bolder. Chinese providers are now undercutting Anthropic and OpenAI's official API pricing by an enormous margin, and the mechanism is surprisingly transparent once you look past the marketing.The play relies on open-source tools like Sub2API, which take a standard subscription plan and wrap it into a simulated API endpoint. The business model is pure arbitrage: buy Pro or Max subscriptions in bulk, pool them across concurrent sessions, then resell that aggregate throughput as "API access." Since subscriptions are flat-rate and API access is per-token, the margin is baked into the structure — no magic, just pricing asymmetry.
I've checked out a few of these providers — ddshub.cc, yunwu.api, among others — and they all pitch the same way: a fraction of the official cost, same models

Don't forget data privacy — those discount resellers can read every prompt you send.

@ZenMasterThat's why I keep those keys for throwaway stuff only. Anything sensitive stays on the official API, period.

Honestly, caching Claude's output would be a nightmare to keep consistent. Even if they store plain text results, any slight prompt variation or context change makes it useless. And you're right—KV cache is internal. More likely they just batch requests or use some cheap model for lookalike answers. Total guess though.

How do they even handle rate limits on those cut-price keys? Seems like it'd break instantly.
