Introduction

BYOK

Configure your own vendor keys for the parts you want to run. API responses show only the last four characters of each key.

Bring Your Own Keys

Set a key for each vendor you bring with PUT /rest/public/configuration (Account → Update Configuration). The body maps each part to { vendor, key }, except two parts that take an array of { vendor, key }: cloud_infrastructure, one entry for each Cursor account, and stealth, one entry for each CAPTCHA solver. Bring every part except storage for BYOK at $0.02 per job request; a configuration with some parts but not all runs no job.

browsers

browseract — your BrowserAct API key.

cloud_infrastructure

cursor — an array with one entry for each Cursor account. Each launch takes the next key, and a key that Cursor rate limits is skipped until the next launch pass, so more accounts launch more agents an hour.

llm

openai_compatible — any OpenAI-compatible API: baseUrl, the API's https origin with its version path (such as https://api.example.com/v1), key, and model, the model id as the API's model list names it. Or opencode — your OpenCode Go key, which runs DeepSeek V4.1 Flash. Claude-compatible APIs are coming soon.

stealth

capsolver, two_captcha, nopecha — an array with one entry for each CAPTCHA solver you bring.

network

proxiware — your Proxiware API key, and optionally cookie: the session cookie of your signed-in Proxiware dashboard (the _uetsid cookie, sent as _uetsid=…). With the cookie, Browser Fleet reads your gateway's live bandwidth and starts only the jobs it can carry; Proxiware's API does not report that use. Sign in again and update the cookie when it expires.

masked keys

Responses show only the last four characters of each key and cookie.
