Hosted API access for the official OpenAI Codex CLI

Run Codex locally. Bill it through one hosted API.

Codex API gives developers instant wallet-backed access for the public @openai/codex@latest CLI. Start new coding sessions, resume local project history, use web search, track token spend, and recharge through Stripe without replacing the official CLI.

Official Codex CLI support

A provider layer, not a replacement CLI.

The official Codex CLI still runs on the user's machine. Codex API supplies the hosted Responses-compatible endpoint at https://codexapi.pro/v1, plus account billing and usage visibility through the dashboard.

Included surfaces

Client dashboard for token, balance, and setup commands.
Admin dashboard for account and credit management.
Responses-compatible API routes under /v1.
Verbose API documentation under /api-docs.
