About nullsink
nullsink provides a handy, direct API proxy for several frontier and also open-weight AI models. It’s pretty simple really. You buy a prepaid key, top it up with Monero or Bitcoin, then point your own tools right at it. Seriously, no sign-up process, no KYC checks, just a key generated in your browser. This service mirrors Anthropic and OpenAI wire formats, so you can pretty much use any stock SDK and only change the base URL and the key. That’s a big plus for developer convenience.
It’s designed to be stateless and really big on privacy; they don’t keep request logs or even your IP address. This helps keep things confidential. You do need to set a `max_tokens` or `max_completion_tokens` on every request though, or it’ll get rejected. Current supported models include several Claude versions (like claude-opus-4-8) and OpenAI-compatible models (like gpt-5.5), alongside some open-weight ones such as glm-5-2 and kimi-k2-6. They even have Tinfoil for sealed privacy.
Payments are handled in XMR or BTC, single use addresses for each transaction. You gotta pay the full amount in one go. There's about a 10% markup on top of the provider's rate, which is fair enough for the service. Payment typically confirms in like 20-45 minutes depending on the coin. One thing to know: no refunds possible and if you lose your key, your credit is gone. Treat it like cash, you know? It’s an experimental service, so brief outages might happen. But if you need an easy, private way to tap into various large language model APIs without all the usual account hassles, this might be your thing. It really focuses on quick, anonymous access.
