AiPayGen vs OpenRouter
An honest comparison of two different approaches to AI APIs. Built-in tools vs model routing. Per-call pricing vs token pass-through.
Last updated: March 2026
TL;DR
AiPayGen gives you 65+ pre-built tools (scraping, RAG, vision, sentiment, code gen) with per-call pricing and x402 crypto payments. OpenRouter gives you access to 200+ AI models from multiple providers with token-based pass-through pricing. They solve different problems: AiPayGen is a toolbox, OpenRouter is a model router. If you need built-in capabilities like web scraping or MCP server support, choose AiPayGen. If you need access to many models through a single API, OpenRouter is hard to beat.
