GPT / OpenAI API Relays
84 relays listed
OpenAI's GPT models are the most widely used family of large language models, but the official API still comes with billing and access friction for a lot of developers outside the US. An OpenAI API relay resells access to an official account and typically accepts a wider range of payment methods, making it one of the most common ways developers get GPT access up and running quickly.
Every relay listed here supports OpenAI models. GPT usage volumes tend to run high, so the multiplier has an outsized effect on your total spend — comparing multiplier and minimum deposit up front is worth the five minutes it takes.

How to choose one
At GPT-scale usage, the gap between a 1x and 2x multiplier compounds fast — pick the lowest multiplier you can find for anything you'll run at volume.
Confirm the relay actually has the model you need (GPT-4o, the o-series, etc.) — some relays only onboard the most popular models.
For high-frequency calling, check the relay's rate limits and peak-hour stability; a small load test before committing is cheap insurance.
Frequently asked questions
Can I use the OpenAI API without a US card?
Yes — an OpenAI API relay lets you top up with a local card, crypto, or other supported payment methods and start calling the API right away, no US-billable card required.
Why are some GPT API resellers cheaper than official?
Relays get pricing headroom from bulk purchasing, multiplier-based markup, or exchange-rate differences — some models come in below official pricing, others above. Compare multipliers rather than assuming any relay is automatically cheaper.
Is a relayed GPT API compatible with the official SDK?
Almost all of them speak the standard OpenAI request/response format — just point base_url and the API key at the relay, no code changes required.
