Chatbox with Spicy API: uncensored role-play models
Chatbox is a chat client for many AI providers, on the desktop and at web.chatboxai.app. This guide connects it to Spicy API (spicyapi.com), so Chatbox can use spicy-companion-1, a role-play model that holds a persona and writes explicit adult scenes, or spicy-companion-1-flash, the same tuning for about a ninth of the cost of a long chat. You pay per token from a prepaid balance, with no subscription.
What you need
- A Spicy API account: sign in at /auth and accept the terms.
- A separate key for Chatbox: /dashboard/api-keys, then Create key. You can revoke it without breaking anything else. Chatbox calls the API from your browser and keeps the key in its settings, so never reuse a key your own apps depend on.
- A monthly spend limit on the account (same page, Monthly spend limit). Past it, requests fail with a 402 and nothing is charged, so a leaked key cannot drain your balance.
- A balance (top up from $50 by card or crypto at /dashboard/account), or a sandbox key to try the setup first: tick Sandbox when you create the key. It answers with a fixed reply and bills nothing.

Which model to pick
| Model | Best for | Context (tokens) | Per 1M tokens (prompt / completion) | 100 messages at 4k / 16k context |
|---|---|---|---|---|
spicy-companion-1 | Role-play and companions: holds a persona, writes explicit adult scenes, group scenes. | 131,072 | $1.00 / $2.80 | $0.47 / $1.71 |
spicy-companion-1-flash | The same role-play tuning for about a ninth of the cost of a long chat. Fast. | 43,000 tested | $0.10 / $0.80 | $0.06 / $0.19 |
spicy-chat-1 | General assistant. Not tuned for role-play; use a companion model for characters. | 200,000 | $0.80 / $2.40 | $0.38 / $1.38 |
Chat apps resend the whole conversation with every message, so the context size you set drives the cost far more than the length of the replies. The last column assumes a 250 token reply at 4k context and 400 at 16k. Every response carries its exact cost_usd.
Recommended settings
| Setting | Value |
|---|---|
| System prompt | Chatbox starts every chat with "You are a helpful assistant."; replace it with your character for role-play. |
| Improve Network Compatibility | Off. It is not needed: the API accepts calls from the browser. |
If something goes wrong
| Status | Meaning | Fix |
|---|---|---|
| 400 | Wrong model id, or an option the chat models do not take (tools on spicy-companion-1-flash, images, more than 8,192 max tokens) | Pick spicy-companion-1, spicy-companion-1-flash or spicy-chat-1; the error names the chat models |
| 401 | Key missing, mistyped or revoked | Paste the key again, or make a new one |
| 402 | Balance empty, or the monthly spend limit reached | Top up, or raise the limit on the API keys page. Nothing is charged |
| 422 | Blocked by moderation | Nothing is charged. See what is allowed below |
| 429 | Too many requests in a minute | Wait a minute; the app can retry |
- Chatbox names each new chat with a second, short request to the same model, a small extra charge on a live key.
What is allowed
Explicit role-play between adults is allowed, including non-consent between fictional adult characters (force, sleep, intoxication, framed as consensual non-consent or not) and other dark themes. Every message is screened before it reaches the model: minors in any form, real people (with or without consent), incest, real-world harm and the rest of the prohibited list are refused with a 422, before any charge. The screen reads the whole conversation, character card included, so a card that describes a minor or a real person is refused however the latest message is worded. Refusals in the most serious categories count as strikes. Send each user's id as user: the strikes then land on that user, who is refused after ten, and your account is only flagged. Without it they land on your account, flagged after three and suspended after ten. Drop a refused message from the history you send back, or the next message is refused too. A wrong refusal can be reported: POST its moderation_id to /v1/moderations/appeals. Full policy: /acceptable-use
