Coinbase Developer Platform announced that the CDP SQL API now supports USDC fee collection per request via an x402 model, allowing AI agents to query Coinbase's indexed blockchain data without requiring an API key, account, or human approval.
This update packages the 402 payment request, signing, and settlement processes into a single HTTP stream, moving toward a pay-per-use model for both wallet functionality and cryptocurrency data querying.
- The CDP SQL API charges USDC per request using x402.
- The AI agent can query Coinbase blockchain data without requiring an API key or account.
- 402 payment, signing, and settlement run in a single HTTP stream; this will expand the infrastructure for smart agents.
CDP SQL API adds a mechanism for charging USDC fees based on requests.
The CDP SQL API now supports charging USDC per request via the x402 model.
According to an announcement on February 13th, the x402 mechanism allows for the completion of 402 payment requests, signing, and settlement within the same HTTP stream. The goal is to create pay-per-user access, instead of traditional access methods based on accounts or API keys.
Coinbase stated that its SQL API CDP is the first CDP service to support x402. The company also said it will continue to deploy more infrastructure to support smart agents in the future.
AI agents can query indexed blockchain data without requiring approval.
The AI agent can directly query indexed Coinbase blockchain data without requiring an API key, account, or human approval.
This design targets an automation scenario: agents can pay USDC per request to use the API, from data queries to wallet-related capabilities. Combining payment and processing within a single HTTP stream reduces operational friction when agents need on-demand access.
