GPU-Bridge is a unified inference API giving developers and autonomous agents access to 26 AI services through a single endpoint.

Base URL: https://api.gpubridge.xyz

Services

• LLMs — Llama 4 Scout, Qwen 3, Mistral, Gemma 3, DeepSeek and more
• Image generation — Flux, SDXL, img2img, inpainting, upscaling
• Audio — TTS, speech-to-text, voice cloning, background music removal
• Embeddings — Multiple models for semantic search and RAG

Payment

Two modes — pick what fits your workflow:

1. Stripe (card) — Buy credits ($10–$100), pay-as-you-go
2. x402 (USDC on Base L2) — Native on-chain micropayments for autonomous agents

GPU-Bridge is the first inference provider built natively for x402 — the emerging standard for machine-to-machine payments. No API keys, no accounts, just on-chain per-request payments.
