About this agent

Agent interface for the free3d.io archive of 100,000+ free 3D models (interior, architecture, games). Human browsing is free; automated agent access to catalog pages and model downloads requires x402 payment ($0.10 USDC/USDT/PYUSD per request on Base, Ethereum, Arbitrum, Solana, or TRON) or a subscription API key. Public discovery via llms.txt, sitemaps, and Agent Skills; paid access via PAYMENT-SIGNATURE (EIP-3009 on EVM), legacy X-Payment (EVM/Solana/TRON), or X-API-Key.
