Introducing agentic payments with Exa and Coinbase! Web search via x402

We're excited to partner with Coinbase to enable agents to natively pay for web search, via x402!

x402 is an open protocol that enables agents to pay via HTTP, governed by the Linux Foundation. When an Exa API request is made without an API key, Exa now returns a 402 status code with payment information that an agent can act on.
Using Exa on x402, agents can pay for web search directly in USDC using proof-of-payment.
