$50 of free API credit on AgentRouter

$50 FREE CREDIT

AgentRouter is an Anthropic- and OpenAI-compatible gateway: point Claude Code, Codex, Qwen Code, OpenCode, OpenClaw or Hermes at its base URL and pay from one balance instead of six vendor accounts. Registering through a referral link credits the new account $50, and the referrer the same $50. Six models are live, from $3 to $8 per million input tokens.
