Why it costs less

We buy discounted capacity through agreements with intermediaries.

The discount applies to the price of the key, not to a hidden token rate. Credit is deducted for actual usage at each provider's official list rates. We serve the advertised official models without substituting cheaper alternatives. This is not the price available when buying directly from the official providers. This price depends on third-party agreements that may change, so the refund policy covers purchases for 12 months from purchase while the credit remains usable.

Key benefits

No email or KYC; Zrelay stores no prompts, responses, or IPs.
Pay in BTC, without an international card or identity verification.
Free trial key: no payment or personal data required.
Use official models, with no cheaper-model substitutions.
The discount applies to the key price, not token rates.
Credit decreases with actual usage, with no monthly reset.
Keep native formats; only change the base URL.

Requests are transmitted to third parties in the request path, whose own retention policies apply.

Early tester feedback

Notes from private testers.

These comments come from people invited to test Zrelay. They are early feedback, not paying-customer reviews or purchase ratings.

Joined the private test to see if it was legit. Pointed Claude Code at the endpoint, set the base URL, and Opus 5 just streamed. The native request format worked without changing my setup — that's the part I cared about.

Anonymous userIndie dev · Madrid

For a side project it was straightforward to test: one key, native wire format, and no SDK changes to my setup.

Anonymous userSolo founder · Ljubljana

I was skeptical, so I started with a small test. The request format worked as documented, and support answered me directly on Telegram within the hour.

Anonymous userHobbyist dev · Tokyo

I run a small automation agency and was burning through a Claude Max plan that just wasn't enough some months. Switched a few client workflows to a Zrelay Claude key and the cost predictability alone was worth it. It's prepaid, so I always know exactly where I stand.

Anonymous userFreelance dev · Prague

Honestly the reason I gave it a shot was that there's no subscription. The Grok key uses the same request format as the official API. I had a hiccup on day one, and support swapped the key without me having to chase.

Anonymous userBackend dev · Oslo

Testing was simple — I changed one environment variable and my GPT client connected. The provider can be changed later from the portal while keeping the remaining balance.
