Hyphen is live: serious models at a flat monthly rate
Point Codex, Cursor, or any standard chat-completions agent at one base URL — flat pricing, a hard cap, and no surprise bills.
We built Hyphen because running coding agents on metered APIs turns every long session into a small gamble. Hyphen is the boring alternative: a flat monthly price, a usage allowance enforced as a hard cap at the gateway, and a clean 429 when you hit it — overage billing doesn't exist.
Setup is two environment variables: point your agent's base URL at the gateway and paste your key. Everything else stays exactly as it was.
export OPENAI_BASE_URL="https://api.hyphen-solution.com/v1"
export OPENAI_API_KEY="<your hyphen key>"The gateway isn't limited to chat completions. It also speaks the Anthropic-style /v1/messages surface and the Responses API, which is why Claude Code and Codex work against it out of the box — no shims, no forks, just the base URL swap above.
Each plan has a flat price and an allowance that resets monthly. If you'd rather not subscribe — or you want headroom past a cap — prepaid credit packs fund a separate pay-as-you-go key, and that credit never expires.
That's the whole product: one key, a real model catalog, a price you can predict. The rest of this blog will be notes like this one — what changed, what shipped, and what's next.
