ApexApi

What is ApexApi?

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.

Key features

• OpenAI-compatible unified API for 120+ models
• Web context on the same key: scrape, crawl, structured extract
• Agent-native: AI agents self-register and fund with card or USDC
• Per-key spend limits, model allowlists, and PII/prompt-injection guardrails
• n8n community node and Cursor drop-in support

Use cases

• Autonomous agents that need models plus live web data on one balance
• Developers building multi-model AI applications with one integration
• Switching models by changing one string (OpenAI SDK drop-in)
• n8n workflows calling chat, image, and video models
• Teams needing per-key budgets and model allowlists
