LLM chat completions for AI agents — no API key, no account, no signup; pay per
LLM chat completions for AI agents — no API key, no account, no signup; pay per call in USDC on Base. POST JSON { prompt } or { messages: [{ role, content }] }; optional model (OpenRouter slug), max_tokens (default 800, max 2000). Routes across a 5-model fallback chain so one unavailable model doesn't fail the call. Returns { model, content, usage, latency_ms }. For agents that need inference without holding an OpenAI or Anthropic key.
