About LLM API Guide

LLM API Guide is a tutorial site for developers about AI coding tools (Codex CLI, Claude Code and others) and model APIs: setup, pricing and troubleshooting.

Who maintains it

The site is maintained by the SeedRouter team. SeedRouter (seedrouter.net) is an AI model API gateway launched in May 2026. We write up the configuration and troubleshooting knowledge we gather while running it.

Affiliation

Articles use SeedRouter as the worked example and recommend it. We have a direct interest in SeedRouter, so please read with that in mind. The setup steps also work with other compatible gateways.

Editorial principles

• Configuration examples come from settings that actually work, and every article shows its published and updated dates.
• Information that changes, such as prices, is dated and sourced; the provider's live page is final.
• If you find a mistake, tell us and we will correct it and update the date.
