Brave Search API now accepts agentic payments via the x402 protocol

Brave Search API now supports agentic payments through the open x402 protocol, allowing developers and AI agents to pay for searches on-demand using USDC stablecoin on the Base blockchain without requiring traditional API key authentication. Requests are priced at $0.005 per search, with payment verified through blockchain transactions before results are returned, and users can get started by setting up a CLI wallet like Purl Wallet and funding it with Base-native USDC.
