One OpenAI-compatible API key for 500+ AI models
Replace separate OpenAI, Anthropic and Google credentials with a single key and switch models by changing one line of code.
Route text, reasoning, coding, image, audio and video workloads through one OpenAI-compatible base URL without rewriting your app.
Line-item pricing per model with discounts below official vendor rates, pay-as-you-go with no monthly subscription or minimum spend.
A real-time dashboard tracks spend, latency and call volume so you can set budget alerts and compare models side by side.
One API key, one balance, 200+ text, image, video and audio models
Connect with the base URL https://gptproto.com/v1 and reuse your existing OpenAI-style request and response shapes across every model in the catalogue.
Text, image, video and audio generation are all served through the same balance and account, so you replace several vendor subscriptions with one.
Route requests across providers so a dead or retired route can be moved with a configuration change instead of a code rewrite.
Top up in increasing increments from around $15 to $5,000 and above, with a bonus percentage added at higher tiers and no recurring commitment.
