Coinbase has launched a CDP SQL API that supports x402 payments, enabling AI agents to autonomously access on-chain data

BlockBeats News, February 13th, the Coinbase Developer Platform (CDP) announced the launch of an SQL API supporting x402 payments, enabling AI agents to access Base's indexed data such as blocks, transactions, token transfers, and decoding events on-demand without the need for an API key, account registration, or manual intervention.

Each SQL query is priced at a fixed rate of $0.1, settled instantly on-chain via USDC. The x402 protocol streamlines the payment process: an agent receives a 402 error response with the payment request, signs a USDC payment proof, and promptly receives the query results.
