01 · How it works

Nobody plans on five AI accounts.

Connect them once. Every app you use gets one key, and each request finds its cheapest way through.

Your accounts, one key

Connect once and every model on the account answers to your gf- key, at your own rates.

A free lane, no account

Pooled free providers answer what you have no account for. No card, no trial clock.

The cheapest route, every time

Live prices, ranked per request. Same model, the lowest price you hold.

02 · Cost-optimized routing

The same model, bought at the best price you hold.

Prices from OpenRouter and Vercel plus our own vendor tables, ranked against the accounts you attached, on every request.

  1. Cheapest capable wins

    A provider that doesn't carry the model is skipped. You get the model you asked for; only the road changes.

  2. Price beats manual order

    If your fallback is cheapest today, it wins today. No re-auditing when a vendor moves a price.

  3. On when you say so

    One switch per account. Leave it off and your manual order is honored exactly.

  4. Your bill stays yours

    Providers bill you directly. A paid model with no account behind it gets a clear 402, never a surprise charge.

03 · Everything it reaches

One key, all of this behind it.

04 · Setting up

Three steps, none of them a terminal.

  1. STEP 01

    Make your key

    Sign up and you land on it: one line beginning gf-. It is shown once, so keep it somewhere safe.

  2. STEP 02

    Paste it into your app

  3. STEP 03

    Ask for a model

    The free lane, or anything on an account you connected. Same key either way.

Setting this up in code instead

Any client that accepts a custom base URL works. For the free lane use openrouter/free as the model (the catalog endpoint lists paid models only). 

# check your key before configuring anything else
curl https://gate-forge.metalgames.xyz/v1/chat/completions \
  -H "Authorization: Bearer gf-YOUR-KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"openrouter/free",
       "messages":[{"role":"user","content":"Say hi in five words."}]}'

stream: true streams. Free usage is metered, so a low spend cap will cut it off.

05 · Part of HEPHforge

One key opens the whole forge.

Every HEPHforge tool draws its models through this gate, on your accounts, at your best price. Sign in once and the whole wall knows you.

One login

The session that opens GATE opens every tool. No twelve accounts, no twelve billing pages.

No vendor keys in tools

Tools hold a route through the gate, and the gate fails closed when a request should not pass.

Agents pay your price

An agent working overnight in NODEforge pays the same live-ranked price you would in Cursor.

A workshop, not a pile of tabs. Forged by Haephestus inside a studio that uses it every day.
