# DeepSeek API key (/docs/providers/deepseek-key)

The DeepSeek API key account answers with a key from DeepSeek. The wallet lists it as DeepSeek under "With an API key", with the id `deepseek-key`.

## What the visitor needs [#what-the-visitor-needs]

A DeepSeek API key. DeepSeek bills the account that owns the key.

## Connect [#connect]

1. The visitor creates an API key in DeepSeek's console, on the account that should pay.
2. In the wallet, the visitor picks DeepSeek under "With an API key".
3. The visitor pastes the key in the "DeepSeek API key" field and presses Connect.

The wallet keeps the key in its encrypted vault, without the spaces around it. It makes no test call, and a wrong key shows up as the provider's error on the first answer. The key has no expiry in the wallet and stays in the vault until the visitor removes the account.

## Models [#models]

The wallet lists the models of `https://api.deepseek.com/models`, newest first. The wallet leaves out the ids that name another kind of model: those containing `embed`, `audio`, `realtime`, `transcribe`, `tts`, `image`, `dall`, `whisper`, `moderation`, `search`, `ocr` or `codex`. It keeps the list for a day. The visitor picks the account's default model in its settings, and a model per site with the buttons of the side panel. Without a choice, the account answers with `deepseek-chat`.

## Usage and limits [#usage-and-limits]

The wallet reads `x-ratelimit-remaining-tokens` and `x-ratelimit-limit-tokens` on each answer that carries them. The room left is the remaining tokens divided by the limit. Without these headers, the card keeps saying "Usage shows after the first answer", and Auto ranks the account among the accounts with no reading.

## Calls [#calls]

Answers come from `https://api.deepseek.com/chat/completions` in the OpenAI chat completions protocol, with the key. All four request options reach DeepSeek.
