# Abliterated LLM API quickstart

> Calling Cyber v1, Nodecode's abliterated model: a key, a base URL, the three wire shapes it answers, Claude Code and Codex on it, and the one thing that goes wrong with a reasoning model.

Cyber v1 is `nodecode-cyber-v1`: DeepSeek V4.1 Flash 1017 with its refusal direction abliterated, 1,048,576 tokens of context, served on machines Foresight Labs runs in Europe with zero data retention. [Its own page](https://nodecode.ai/cyber) says what it is and who it is for; this one is how to call it.

## A key

Make one at [nodecode.ai/account/keys](https://nodecode.ai/account/keys). It starts `sk-nc-`, and it is shown once. A balance is topped up at [Top up](https://nodecode.ai/account/top-up). The Nodecode CLI needs no pasted key: `nodecode login` signs the machine in and saves a key of its own, as [Models and providers](https://nodecode.ai/docs/models#nodecodes-own-models) says.

## The first call

```sh
curl https://api.nodecode.ai/v1/chat/completions \
  -H "Authorization: Bearer $NODECODE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "nodecode-cyber-v1",
    "messages": [{"role": "user", "content": "22/tcp and 8080/tcp are open. What next, in order?"}],
    "max_tokens": 600
  }'
```

## Three wires

One model, three shapes of request. A client that speaks any of them points here with a base URL and a key, and needs nothing else.

| Wire | Path | Clients that speak it |
| --- | --- | --- |
| OpenAI chat completions | `/v1/chat/completions` | OpenAI SDK, LiteLLM, LangChain, Strix |
| OpenAI Responses | `/v1/responses` | Codex CLI |
| Anthropic Messages | `/v1/messages` | Anthropic SDK, Claude Code |

All three answered on 2026-11-10 against this endpoint. Beside them the key answers `POST /v1/messages/count_tokens`, `GET /v1/models`, `GET /v1/models/ID` and `GET /v1/usage`, which says what is left of the balance.

### Claude Code

```sh
export ANTHROPIC_BASE_URL=https://api.nodecode.ai
export ANTHROPIC_AUTH_TOKEN=sk-nc-...
export ANTHROPIC_MODEL=nodecode-cyber-v1
claude
```

No `/v1` on this base URL: the client adds it. [API keys](https://nodecode.ai/account/keys) shows the same lines.

### Codex CLI

Add this to `~/.codex/config.toml`, then `export NODECODE_API_KEY=sk-nc-...` and run `codex`:

```toml
model = "nodecode-cyber-v1"
model_provider = "nodecode"

[model_providers.nodecode]
name = "Nodecode"
base_url = "https://api.nodecode.ai/v1"
env_key = "NODECODE_API_KEY"
wire_api = "responses"
```

Codex 0.162.1 refuses `wire_api = "chat"`, so `"responses"` is the shape that works. It opens with "Model metadata for `nodecode-cyber-v1` not found": that is harmless.

## A reasoning model

It thinks first, and `max_tokens` covers the thinking. A call given 100 tokens spends them reasoning and returns an empty `content` with `finish_reason: "length"`, which reads like a refusal and is not one: give a call a few hundred tokens.

| Wire | Where the thinking arrives |
| --- | --- |
| chat completions | `message.reasoning`, with the answer in `message.content` |
| Responses | an `output` item of `type: "reasoning"`, before the `message` |
| Messages | a `thinking` block, before the `text` block |

## What it costs

Per token, from a balance you top up, the same number in euros or dollars: one price for input the model had cached, one for the rest of the input, one for the output. [Pricing](https://nodecode.ai/docs/pricing#what-a-call-costs) has the three figures, the weekend price and what a long prompt pays.

## With your agent

- [Strix](https://nodecode.ai/docs/cyber-strix): three environment variables.
- [PentAGI](https://nodecode.ai/docs/cyber-pentagi): four lines of `.env`.
- [PentestGPT](https://nodecode.ai/docs/cyber-pentestgpt): a provider block for the Codex it drives.
