What is nullsink?
nullsink is a privacy-first API gateway that provides anonymous access to Claude, GPT, and confidential open models — no account, email, card, or subscription required. Instead of signing up, you fund a bearer API key with a one-time payment starting at $2, using Monero or Bitcoin. Once funded, that key works with native Anthropic or OpenAI-compatible clients, giving you a familiar developer experience wrapped in an unusual degree of anonymity.
The service is built around a simple premise: AI access shouldn't require identity. Credit never expires, and nullsink keeps no request-content or client-IP logs. Its AGPL source code, architecture, and trust-model limitations are published openly, so you can see exactly what you're getting — and what you're not.
Who it's for
- Privacy-conscious developers who want to build on frontier models without tying API usage to a personal identity or payment method.
- Journalists, researchers, or activists operating in sensitive contexts where a paper trail of AI queries could create risk.
- Hobbyists and tinkerers who prefer a pay-as-you-go model over subscriptions and want a low-cost entry point — from $2 — with no recurring commitment.
Key features
Anonymous bearer keys
You fund a key with Monero or Bitcoin, and that key is all you need. There's no account creation, no email verification, and no card on file. The key works directly with Anthropic or OpenAI-compatible clients, so integration is straightforward.
Credit that doesn't expire
Unlike prepaid services that push you to spend within a window, nullsink credit remains available indefinitely. You can fund $2 today and use it months later without penalty or pressure.
No request or IP logging
nullsink explicitly keeps no logs of request content or client IP addresses. This isn't a marketing claim buried in fine print — it's a core architectural decision, documented in the published source and trust-model notes.
Open-source transparency
The AGPL source code is public, along with the architecture and trust-model limitations. You can audit how the service works, understand its boundaries, and make an informed decision about whether it fits your threat model.
What stands out
nullsink sells access to AI models the way a cash-only newsstand sells a newspaper — no identity, no subscription, no trail.
That's the core edge: it's not just an API proxy, it's a deliberate exercise in removing every possible point of identification. The Monero/Bitcoin funding, single-use addresses, and absence of logs combine into a service that treats privacy as the product, not a feature. The published source code and explicit trust-model limitations also set it apart from opaque competitors — you're told exactly where the boundaries are, even when those boundaries aren't flattering.
Worth checking out if…
You value anonymous access to frontier AI models, want to avoid subscription lock-in, or need a low-cost way to experiment with Claude or GPT through standard clients. It's also worth a look if you're curious about how far a no-logs, crypto-funded API service can go — and where it can't. Just be aware: payments are final, credit can't be transferred or cashed out, and losing your key means losing your credit. If those terms sound acceptable, nullsink offers a genuinely different way to pay for AI.
