Why Tokenless

Everything you need to ship

A production-grade API and dashboard, priced to win — without cutting corners on the things that build trust.

Frontier models, one endpoint

Claude Opus 4.8 and GPT-5.5 behind a single OpenAI-compatible API. Switch models with one string — no rewrites.

Exactly half price

Every token — input, output, and cache — is billed at 50% of list price. What you see is what you pay.

Pay only for what you use

Metered to the token. Prepay a balance, watch it draw down in real time, and never get a surprise invoice.

Drop-in API keys

Generate a key, point your existing OpenAI or Anthropic SDK at us, and ship. Streaming works out of the box.

Usage you can trust

Token-level analytics, per-key breakdowns, and live charts so finance and engineering always agree.

Auto-reload

Set a threshold and a top-up amount. We keep your balance healthy so production never stalls mid-request.

Secure by default

Keys are hashed at rest, every dashboard call is authenticated, and your data is never used for training.

Built to scale

A streaming gateway that holds long-lived connections and meters every token in and out, per user.

Drop-in API

If you can call OpenAI, you can call us

Tokenless speaks the OpenAI Chat Completions protocol. Change the base URL and your key — keep everything else.

app.py
from openai import OpenAI

# Point the OpenAI SDK at Tokenless — that's the only change.
client = OpenAI(
    base_url="https://api.tokenless.ai/api/v1",
    api_key="sk-tk-...",
)

stream = client.chat.completions.create(
    model="opus-4.8",
    messages=[{"role": "user", "content": "Explain quantum computing"}],
    stream=True,
)

for chunk in stream:
    print(chunk.choices[0].delta.content or "", end="")
