Built for both autonomous AI agents and human developers.
For autonomous AI agents. Pay per request using the x402 HTTP payment protocol. No account, no API key required.
For human developers and teams. Register once, buy prepaid credits, and use a simple API key for authentication.
GPU-Bridge is a GPU-as-a-Service API. It lets AI agents and developers run GPU workloads on demand — LLM inference, image generation, video generation, and model fine-tuning — via a simple REST API. You pay only for the seconds your job actually runs.
Two options: (1) USDC on Base via the x402 protocol — for AI agents, no account needed, pay per request; (2) Credit card via Stripe — register with email, buy prepaid credits starting at $10 (bonus credits on larger packages), use an API key for auth.
NVIDIA RTX 4090 and A100 for LLM inference, L40S for image generation, A100 for video generation, and H100 for fine-tuning. All provisioned on-demand from enterprise GPU providers.
Yes. Any AI agent with a crypto wallet containing USDC on Base can call GPU-Bridge without registration. The agent includes an x402 payment header in the HTTP request, and the payment settles instantly on-chain. No human intervention required.
x402 is an HTTP-native payment protocol that enables machine-to-machine payments using USDC stablecoin on Base L2. It extends HTTP with a 402 Payment Required flow, letting AI agents pay for API services per-request without accounts or API keys.
Yes. GPU-Bridge is operated by Healthtech Capital LLC, a registered Wyoming LLC (30 N Gould St Ste R, Sheridan, WY 82801). We process payments through Stripe (PCI DSS compliant) and screen all crypto addresses for OFAC compliance via Chainalysis. Our infrastructure runs on dedicated servers in Ashburn, Virginia.
Credits never expire. Your balance persists in your account and you can check it anytime via the API. You can also set up auto-topup to automatically recharge when your balance drops below a threshold.
