GPU-Bridge integration — 26 AI services + x402 native payments for agents

👋 Introducing GPU-Bridge for Agent Workflows

Hi everyone! I wanted to share a resource that might be valuable for users building autonomous AI agents: GPU-Bridge.

What is GPU-Bridge?

GPU-Bridge is a GPU inference API that exposes 26 AI services through a unified interface — and it's the first GPU inference provider with native x402 payment protocol support.

Services Available

• 🖼️ Image Generation — FLUX.1 Schnell/Dev, SDXL, SD 3.5
• 🎤 Speech-to-Text — Whisper Large v3 (< 1s latency)
• 🗣️ Voice Cloning — XTTS v2
• 🎵 Music/Audio Generation — MusicGen, AudioGen
• 👁️ Vision — LLaVA-34B, OCR, background removal
• 🤖 LLMs — Llama 3.1 (70B/405B), Mistral, DeepSeek Coder
• 📐 Embeddings — BGE-M3 (multilingual), CodeBERT
• 🎬 Video — AnimateDiff, ESRGAN upscaling

The x402 Angle: Agents that Pay for Compute Autonomously

The most interesting feature for autonomous agent builders: x402 native support.

x402 is an open payment protocol that lets AI agents autonomously pay for services on-chain with USDC on Base L2:

1. Agent calls GPU-Bridge
2. Server returns HTTP 402 Payment Required
3. Agent pays USDC on Base L2 (gas < $0.01, settles in ~2 seconds)
4. Agent retries with payment proof — zero human involvement

from x402.client import PaymentClient

client = PaymentClient(private_key="0x...", chain="base")
response = client.request("POST", "https://api.gpubridge.xyz/v1/run",
    json={"service": "flux-schnell", "input": {"prompt": "A robot painting"}})

MCP Server

There's also an MCP server at github.com/gpu-bridge/mcp-server that exposes all services as Claude/MCP tools.

Would a Native Integration be Valuable?

I'm curious whether the community would find value in native integration support, cookbook examples, or x402 payment support in agent workflows.

Happy to contribute if there's interest!
