One API key for 120+ AI models plus live web data. OpenAI-compatible.

ApexApi is a unified, OpenAI-compatible AI gateway: one key and one base URL for 120+ models from OpenAI, Anthropic, Google, DeepSeek, Qwen, Mistral and more, billed by usage from a prepaid credit balance. The same key gives agents live web context — scrape any URL, crawl whole sites, or pull structured data — so an agent can read the web and call models without leaving one API. Built agent-native: an AI agent can register, fund itself with a card or USDC on Base, and start calling with no human in the loop (machine-readable onboarding at apexapi.dev/auth.md). Includes per-key spend limits, model allowlists, prompt-injection/PII guardrails, team orgs, and an n8n community node.
