ForgeGrit

What this is

ForgeGrit serves only full-capability frontier models. No 1B toys, no distilled "lite" tiers, no trial credits that expire into a bill. You register, you get a key, you get 100,000 requests a day. That's the whole product.

The API speaks the OpenAI format, so anything already pointed at /v1/chat/completions works by changing two lines.

Quickstart

Base URL:

copyhttps://api-forgegrit.serveousercontent.com

copycurl -X POST https://api-forgegrit.serveousercontent.com/v1/chat/completions \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-opus-5",
    "messages": [{"role": "user", "content": "Say hello"}]
  }'

copyimport requests

r = requests.post(
    "https://api-forgegrit.serveousercontent.com/v1/chat/completions",
    headers={"Authorization": "Bearer YOUR_KEY"},
    json={
        "model": "claude-opus-5",
        "messages": [{"role": "user", "content": "Say hello"}],
    },
    timeout=300,
)
print(r.json()["choices"][0]["message"]["content"])

copyfrom openai import OpenAI

client = OpenAI(
    base_url="https://api-forgegrit.serveousercontent.com/v1",
    api_key="YOUR_KEY",
)

r = client.chat.completions.create(
    model="claude-opus-5",
    messages=[{"role": "user", "content": "Say hello"}],
)
print(r.choices[0].message.content)

copyconst res = await fetch(
  "https://api-forgegrit.serveousercontent.com/v1/chat/completions", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_KEY",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
    model: "claude-opus-5",
    messages: [{ role: "user", content: "Say hello" }]
  })
});
const data = await res.json();
console.log(data.choices[0].message.content);

Models

Pass any of these as model. All full-size — nothing here is a distilled variant.

Live list, filtered to what your key can reach:

copycurl https://api-forgegrit.serveousercontent.com/v1/models \
  -H "Authorization: Bearer YOUR_KEY"

Flagship

ForgeGrit’s own models. Ranked by our tiering, cheapest first — and all $0 here.

Pricing

Every other model here has a published rate card. Below is what each costs on its own API, in USD per million tokens — and what the identical model costs on ForgeGrit.

What that means in practice

A month of moderate agent work — 10M input tokens and 2M output — run on the top model:

Everywhere else the money usually hides

So what's the catch

Honestly: uptime. ForgeGrit runs on self-hosted hardware behind a tunnel, paid for out of pocket. Nobody is billed because nobody is being sold anything — but that also means there is no SLA, no support contract, and no promise the endpoint answers at 3am. /health is the honest answer at any given moment.

The 100,000 daily requests exist to stop one client from starving everyone else. Hit it and you get a 429, never an invoice.

Endpoints

Register

copycurl -X POST https://api-forgegrit.serveousercontent.com/register \
  -H "Content-Type: application/json" \
  -d '{"email":"you@example.com","password":"your-password"}'

Get your key

copycurl -X POST https://api-forgegrit.serveousercontent.com/authenticate/email \
  -H "Content-Type: application/json" \
  -d '{"email":"you@example.com","password":"your-password"}'

Returns api_key, owner_id, and rpd_limit. Logging in again always returns the same key, so there is nothing to lose — if you misplace it, just log in.

Rotate your key

Keys do not expire. If yours ends up somewhere it shouldn't — a screenshot, a commit, a pasted log — rotate it. This revokes every existing key on the account and issues a new one. The old key stops working immediately.

copycurl -X POST https://api-forgegrit.serveousercontent.com/authenticate/rotate \
  -H "Content-Type: application/json" \
  -d '{"email":"you@example.com","password":"your-password"}'

Your account, usage history, and daily limit are unaffected — only the key changes.

Two-factor authentication

ForgeGrit supports time-based one-time codes (TOTP) from any authenticator app — Aegis, Google Authenticator, 1Password, whatever you already use. With it on, a stolen password is not enough to log in, and a code someone captures is dead within thirty seconds.

Enrol in two calls. The first returns a secret and an otpauth:// URI:

copycurl -X POST https://api-forgegrit.serveousercontent.com/authenticate/2fa/setup \
  -H "Content-Type: application/json" \
  -d '{"email":"you@example.com","password":"your-password"}'

Add the secret to your authenticator, then confirm with a live code:

copycurl -X POST https://api-forgegrit.serveousercontent.com/authenticate/2fa/enable \
  -H "Content-Type: application/json" \
  -d '{"email":"you@example.com","password":"your-password","code":"123456"}'

From then on, include code when you log in, rotate, or change your password. Each code works once — reusing one returns code_reused, so wait for the next.

/authenticate/2fa/disable turns it off and takes the same password plus code.

Change your password

copycurl -X POST https://api-forgegrit.serveousercontent.com/authenticate/change-password \
  -H "Content-Type: application/json" \
  -d '{"email":"you@example.com","password":"old","new_password":"new","code":"123456"}'

Your API key survives a password change. Omit code if 2FA is off.

Using ForgeGrit inside someone else’s app

Because keys are free and per-account, apps can ask each user for their own ForgeGrit key instead of shipping one. Good pattern — but get your key here and paste it in.

Streaming

Add "stream": true for server-sent events. Chunks arrive as data: lines, terminated by data: [DONE].

copycurl -N -X POST https://api-forgegrit.serveousercontent.com/v1/chat/completions \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-sonnet-5",
    "messages": [{"role": "user", "content": "Count to five"}],
    "stream": true
  }'

Video

Video generation runs on Hugging Face Spaces, and ForgeGrit does not own that GPU time.

You get one free video a day with no token at all, on ltx-video-fast, drawn from ForgeGrit’s own quota. Past that, bring a token: create a free read token at huggingface.co/settings/tokens and send it as X-HF-Token. Then it is unlimited, any model, on your quota — and the token is never stored.

copy# free — no token
curl -X POST https://api-forgegrit.serveousercontent.com/v1/video \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"ltx-video-fast","prompt":"a fox in snow"}'

Check what you have left with GET /v1/video/models — the free_tier block reports your remaining videos for the day. A failed generation is refunded, so a broken job never costs you your free one.

Generation takes 30 seconds to a few minutes, so the endpoint is asynchronous — you get a job id back and poll it.

copycurl -X POST https://api-forgegrit.serveousercontent.com/v1/video \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "X-HF-Token: hf_your_token" \
  -H "Content-Type: application/json" \
  -d '{"model":"ltx-video-fast","prompt":"a fox walking through snow"}'

Then poll until status is done:

copycurl https://api-forgegrit.serveousercontent.com/v1/video/JOB_ID \
  -H "Authorization: Bearer YOUR_KEY"

Health

copycurl https://api-forgegrit.serveousercontent.com/health

{"status":"ok","inference":"ok"} means inference is up. degraded means the backend is unreachable — retry shortly.

Parameters

Limits & errors

Check where you stand at any time:

copycurl https://api-forgegrit.serveousercontent.com/v1/usage \
  -H "Authorization: Bearer YOUR_KEY"

100,000 requests per day per account — the quota follows the account, not the key, so rotating does not reset it. The counter resets at midnight. There is no paid tier to upgrade to — the limit exists to stop abuse, not to sell you anything.
