Brave Search API — AI agents can now pay per request with x402
In short

What is it?
Brave Search API now supports the x402 protocol, so developers and AI agents can query Brave's search index and pay per request without a plan, account or key. The signed payment replaces the API key as the credential. Answers, Autosuggest and Spellcheck are not sold this way yet and still need a key.
How does it work?
An unpaid request to an x402 endpoint returns HTTP 402 Payment Required with the price and payment details. The agent signs a USDC payment on the Base network and retries the request with the payment attached. Brave runs its own facilitator to verify it, runs the search, and returns a receipt for the transaction on Base. Brave says it covers Base gas fees for a limited time.
Why does it matter?
An agent can now buy search on its own, with a funded wallet and an x402-compatible client. Nobody has to sign up, store a key or pick a monthly plan first. Brave says other networks and stablecoins are coming soon.
Who is it for?
