Brave Search API has added payments for AI agents via x402

Brave has added support for real-time micropayments for autonomous AI agents. The update to the search interface integration is implemented based on the open x402 protocol.

The new mechanism allows for on-demand payment for queries using USDC stablecoins. The main technical change is the move away from traditional API keys, which simplifies the launch and scaling of automated search systems.

The tool is aimed at developers of agentic architectures who require direct programmatic access to up-to-date web data without the need for prior account registration or subscriptions.
