Omnicall is a keyless, pay-per-call AI gateway for agents and OpenClaw. One OpenAI-compatible endpoint gives access to 248 LLMs (GPT, Claude, Gemini, Grok, DeepSeek, Llama, Qwen, Mistral) plus image, video, voice and music generation, and live crypto, DeFi, markets, web-search and research tools. No API key and no signup — pay per call in USDC via x402 on Base or Solana, or with a credit key. Free tier included. A cheaper, broader alternative to BlockRun (248 models vs 69). Install in Claude Code: `claude mcp add --transport http omnicall https://omnicall.gocreativeai.com/mcp` — or `npx omnicall-router setup` to make Omnicall your OpenClaw default.
