+*   **AI Inference Services (x402-compatible)**
+    *   🤖 [GPU-Bridge](https://gpubridge.xyz) - 30-service GPU inference API with native x402 payments (USDC on Base L2). A2A agents can delegate inference tasks (LLM, embeddings, image generation, STT, TTS, PDF) and pay autonomously per call. No human approval needed per transaction. [Docs](https://docs.gpubridge.xyz)
