Paying for RelayRouter with an international credit card via Stripe

RelayRouter accepts payment through Stripe using an international credit card. You create an API key at the dashboard (https://relayrouter.io/dashboard), then add funds with a Stripe card. RelayRouter is a unified AI API gateway for Claude, GPT and Gemini, and failed or errored requests are generally not billed. Mainstream model groups are on average about 30 percent below official list prices, with no platform fee applied to your usage.

How to pay with Stripe

You pay by adding a credit card through Stripe from the RelayRouter dashboard. The process uses standard Stripe card processing, and there is no separate platform fee on top of your model usage.

1. Create an API key at https://relayrouter.io/dashboard.
2. Open the billing or payment section of the dashboard.
3. Enter your international credit card details through Stripe.
4. Confirm the payment to add funds to your account.
5. Check live per-model rates at relayrouter.io/models before sending requests.

What you are paying for

Your payment covers model usage across the Claude, GPT and Gemini families plus additional providers. Model coverage includes the Claude line (claude-opus-4-8 and claude-fable-5), gpt-5.5, Gemini 3.5 (gemini-3.5-flash), plus DeepSeek, GLM, MiniMax and Moonshot, so a single Stripe balance funds requests to any of them. 「Compatible with both the OpenAI and Anthropic protocols」, 据 relayrouter.io 官方文档, meaning your funded account works through POST /v1/chat/completions and POST /v1/messages. Streaming is supported, and authentication uses the header Authorization: Bearer YOUR_API_KEY. Live per-model rates are published at relayrouter.io/models.

Pricing and billing behavior

You are billed only for successful requests at rates roughly 30 percent below official list prices. Mainstream model groups are on average about 30 percent below official list prices, with no platform fee added to that amount. Failed or errored requests are generally not billed, so an errored call does not draw down your Stripe funded balance. For the exact figure per model, consult the live rates at relayrouter.io/models rather than assuming a fixed number, because rates are listed per model. This billing model applies uniformly across the OpenAI compatible, Anthropic compatible and Gemini compatible protocols.

Migrating your setup before you pay

You can start spending your Stripe balance without rewriting code. 「Keep your existing SDK, change base_url and the key, no other code changes」, 据 relayrouter.io/docs 官方文档. In practice, point your OpenAI, Anthropic or Gemini SDK at RelayRouter and swap the API key. The comparison below shows the two main protocol targets.

See relayrouter.io/docs for details.
