[Coinbase: CDP SQL API Now Supports x402 Payments] Coinbase Developer Platform announced that its CDP SQL API now supports charging USDC fees per request through the x402 model. AI agents can directly query indexed Base blockchain data without the need for an API Key, account, or manual approval. This solution completes 402 payment requests, signatures, and settlements through a single HTTP stream, enabling a 'wallet + query' pay-per-use access model. The CDP SQL API is the first CDP service to support x402, and the official statement indicates that more infrastructure for intelligent agents will be introduced in the future.
