Generate images with crypto micropayments

Generate AI images using Nano Banana model on-chain

Generating production-ready images without API keys when you control on-chain payments via USDC micropayments, avoiding vendor lock-in.

• · Text prompt string
• · Optional output directory path
• · Optional model specification (google/nano-banana, google/nano-banana-pro, openai/dall-e-3)

• · Image URL (1024x1024 to 4K depending on model)
• · Image file saved locally

• · BlockRun API (blockrun.ai)
• · x402 protocol for HTTP 402 payments
• · USDC on Base network
• · vLLM (optional)
• · pip/python

• · USDC wallet on Base network with $1-5+ minimum balance
• · Private key stored in BLOCKRUN_WALLET_KEY env var or .env file
• · blockrun-llm SDK installed (pip install blockrun-llm)
• · Internet connectivity to blockrun.ai API

• · Insufficient USDC balance → 402 Payment Required
• · Invalid private key → signing fails
• · Network outage to blockrun.ai → connection timeout
• · Unsupported image dimensions → model returns error
• · High load on BlockRun → rate limiting or queue delays

• · Open-source blockrun-llm SDK on PyPI
• · Transparent x402 protocol (no hidden payments)
• · Local signing of USDC transactions (key never leaves machine)
• · Clear pricing per model ($0.04-0.12 per image)
• · Supports multiple image generation models (Nano Banana, DALL-E-3)
