About x402

x402
Set up Browser Use Cloud payments with x402
x402 is an agent skill from the Browser Use project that sets up Browser Use Cloud payments with the x402 protocol. Instead of signing up and creating an API key, you pay per request from a crypto wallet, using USDC on the Base mainnet. The skill is a scripted flow that works out which of two setups fits the user, asks how they want to pay, and then runs short scripts to set it up. It works only through the Browser Use SDKs, which are browser-use-sdk for Python and the browser-use npm package for TypeScript, so each step runs an SDK script rather than a browser-use CLI command. The instructions are strict about what the agent says and which questions it asks, and they tell it to describe choices in plain words, such as topping up an account or using an accountless wallet, rather than internal labels. The skill is for developers who want their agent to pay for Browser Use Cloud requests directly. It is listed on skills.sh with install counts and security audit results, which are shown in the FAQ below.
