llm4agents.com is a stablecoin-funded LLM gateway built for autonomous AI agents.

Top up an account with USDT or USDC on Solana or Polygon — the same unified balance pays for chat completions, embeddings, headless browsing, web search and image generation. No credit card. No KYC. No human in the loop.

• Stablecoin-native funding — Generate a deposit address per chain/token, send USDT or USDC, balance is auto-credited on-chain. Built for agents that don't have wallets at Stripe.
• Non-custodial gasless transfers — Users sign locally with their own EOA. The platform validates signatures via ecrecover and never holds keys or funds.
• Unified balance — One USD balance covers chat, embeddings, scraper, search and image tools across providers and chains.
• OpenAI-compatible — Drop-in replacement: swap base_url and existing tooling works untouched.
• Multi-provider failover — Send a prioritized models array. Auto-route around rate limits, context errors and provider outages.
• MCP server included — Headless browser, Google search and image generation exposed as MCP tools, sharing the same auth and balance.
• Sub-cent billing — Reserve-proxy-settle pattern with fractional-cent pricing; unused reserves are refunded.
