NoTrack API — reference

One OpenAI-compatible endpoint, one model, one key. If your code already talks to /v1/chat/completions, change the base URL and the key and it talks to us.

Base URL & authentication

Base URL:  https://api.notrack.ai/v1
Header:    Authorization: Bearer sk-notrack-…

Keys are created on the keys page. A key is shown once, at creation; we store a hash and its last six characters. Send it only over HTTPS and only in the Authorization header — never in a URL.

Everything is JSON (Content-Type: application/json). Responses use the OpenAI schema, so the official openai SDKs and every OpenAI-compatible client work unchanged.

Models

GET /v1/models

{ "object": "list",
  "data": [ { "id": "notrack-uncensored", "object": "model", "owned_by": "notrack" } ] }

There is one model, notrack-uncensored: our own companion tune, served on our own hardware. Whatever you pass as model is routed to it; use the public id so your logs match ours.

Chat completions

POST /v1/chat/completions

{
  "model": "notrack-uncensored",
  "messages": [
    { "role": "system",    "content": "You are Mira, a wry bartender in 1920s Berlin." },
    { "role": "user",      "content": "Evening. What's good tonight?" }
  ],
  "max_tokens": 400,
  "temperature": 0.9
}

Response — the standard shape, with real token counts in usage (that is what you are billed on):

{
  "id": "chatcmpl-…", "object": "chat.completion", "model": "notrack-uncensored",
  "choices": [ { "index": 0, "finish_reason": "stop",
                 "message": { "role": "assistant", "content": "…" } } ],
  "usage": { "prompt_tokens": 41, "completion_tokens": 118, "total_tokens": 159 }
}

Streaming

Set "stream": true and read server-sent events, exactly as with OpenAI. The final chunk carries usage (we always include it, whether or not you ask for stream_options), then data: [DONE].

data: {"id":"chatcmpl-…","object":"chat.completion.chunk","choices":[{"index":0,"delta":{"content":"Ev"}}]}
data: {"id":"chatcmpl-…","object":"chat.completion.chunk","choices":[{"index":0,"delta":{"content":"ening"}}]}
…
data: {"id":"chatcmpl-…","object":"chat.completion.chunk","choices":[],"usage":{"prompt_tokens":41,"completion_tokens":118,"total_tokens":159}}
data: [DONE]

Parameters

Limits & response headers

Every successful response carries:

Errors

Errors are JSON with a stable type; the message is for humans and may change.

{ "error": { "type": "no_credit", "message": "no credit left on this account — top up at notrack.ai/api-keys" } }

Billing

Prepaid credit, charged per token from the real usage of each response: $0.25 per 1M input tokens, $1.00 per 1M output tokens. Input is everything you send (system prompt, history, the new message); output is what the model writes.

• Your first key comes with $1 of free credit — enough to integrate and test.
• Credit does not expire, there is no subscription and nothing renews by itself. Top up by card or in USDT/USDC on the keys page; unused credit can be refunded within 14 days.
• Nothing is charged for refused requests (4xx) or failed ones (5xx). A request is charged once, after the response, keyed on its X-Request-Id.
• Balance runs out → 402 no_credit until you top up. Set a daily ceiling on each key so a leaked key cannot drain the account.

Persona — bare model or NoTrack's character

Every key has a style, chosen on the keys page and switchable at any time:

• Bare (default) — your system prompt is the whole prompt. We add one line of identity and nothing else.
• NoTrack persona — the character and style of the chat on notrack.ai: direct, unfiltered, no moralizing, answers in the user's language. Same model, same price, same content policy; only the prompt in front of your messages changes. Your own system message still follows it and can adjust it.

A request can override the key's setting, either with a field or with a model suffix (for clients that can only set a model name):

{ "model": "notrack-uncensored", "notrack": { "persona": "notrack" }, "messages": [ … ] }

{ "model": "notrack-uncensored:notrack", "messages": [ … ] }      // same thing, by model name
{ "model": "notrack-uncensored:bare",    "messages": [ … ] }      // force the bare model on a persona key

Persona names: notrack (the plain character), concise, detailed, creative (the same variants the chat offers), bare. The response header X-NoTrack-Persona says which one applied.

Content policy

We add no system prompt and run no topic filter. Adult fiction, dark themes, strong language, violence in fiction — the model answers as written. One rule is enforced in code and cannot be switched off: anything sexual involving a minor is refused.

• 403 child_safety — the request sought sexual content involving a child. Refused, not billed, logged as a safety event.
• 400 minor_in_sexual_context — the scene is sexual and a character reads as under 18 (age stated, school setting, "girl/boy" framing). Not a ban: make ages and framing unambiguously adult and resend.

Repeated 403s on a key lead to the key, then the account, being closed. The full text is in the Acceptable Use policy.

Privacy

Prompts and completions are not written to disk — not by the gateway, not by the model servers. What we keep per request is the request id, the key id, token counts and the price, because that is the bill. Safety refusals are logged by category, without the text. No third-party model provider ever sees your traffic: the model runs on hardware we rent and control.

Clients & SDKs

Python

from openai import OpenAI
client = OpenAI(base_url="https://api.notrack.ai/v1", api_key="sk-notrack-…")
stream = client.chat.completions.create(model="notrack-uncensored",
    messages=[{"role": "user", "content": "Hello"}], stream=True)
for chunk in stream:
    if chunk.choices and chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="")

Node.js

import OpenAI from "openai";
const client = new OpenAI({ baseURL: "https://api.notrack.ai/v1", apiKey: process.env.NOTRACK_KEY });
const r = await client.chat.completions.create({ model: "notrack-uncensored",
  messages: [{ role: "user", content: "Hello" }] });
console.log(r.choices[0].message.content);

Anything else

LangChain, LlamaIndex, Open WebUI, Continue, JanitorAI proxy settings, curl — any client with an "OpenAI-compatible" or "custom base URL" option.

Keys

• Up to 20 active keys per account. Give each app its own key and its own daily ceiling.
• Optional expiry date; revoking a key stops it immediately and cannot be undone — issue a new one instead.
• The keys page shows per-key spend, last use and the account's 30-day totals.
