Brave announced on November 12, 2026 that the Brave Search API now accepts instant agentic payments through the open x402 protocol. Developers and autonomous AI agents can now query Brave's independent search index, ground responses with web results and pay for each query in real time — without creating an account or managing an API key.
How pay-per-query works
Brave Search API endpoints behind x402 require payment on every request instead of authentication. A query sent without payment receives an HTTP 402 Payment Required response stating the price of the search and the payment details needed to pay it. The agent signs a USDC payment and retries the request with the payment attached; once verified, the search runs and the results arrive with a receipt of the transaction recorded on the Base blockchain.
Brave runs its own payment facilitator, which accepts USDC on the Base network. According to the company, other networks and stablecoins will be accepted soon. The easiest path Brave points to is installing Purl Wallet, a command-line wallet developed by Stripe for agents.
Price: $0.005 per search
Pricing follows Brave's published API rates: $0.005 per request ($5 per 1,000), both for the LLM Context endpoint, built to give search context to agents, and for the web, news, image, video and local search endpoints. Gas fees on the Base network will be covered by Brave for a limited time. Since each request carries its own payment, a Brave Search API account is no longer needed to use the service.
Independent verification
The implementation has already been tested in practice by developers: independent probes published on November 13 sent unpaid requests to Brave's x402 proxy and received the 402 response with a price of 5,000 base units of USDC ($0.005), on the Base chain, signed via EIP-3009 — confirming the behavior described in the official announcement.
The move makes Brave one of the first search providers with its own index to sell per-call access on the x402 protocol, a model in which the signed payment works as the credential instead of a traditional API key.
