Singapore-hosted AI price router

Automatic routing to the cheapest live AI API.

CPEN gives developers one OpenAI-compatible API, real-time price checks, hard USD caps, provider-group status, and automatic route selection for extraction, cleanup, batch jobs, and mini-chat.

Use stable CPEN aliases first. Pin provider groups later when you know exactly what price, uptime, region, or data policy you need.

Cost controls before model hype

The product is optimized for people who care about price ceilings, fallback behavior, and batch throughput more than leaderboard screenshots.

  • No anonymous API traffic
  • Provider group status before dispatch
  • Hard per-request USD caps
  • OpenAI-compatible chat path plus extraction and batch surfaces

Drop-in quickstart

Swap the base URL, keep the OpenAI-style request shape, and set per-request routing caps in USD.
