South Korean business data platform provider COOCON has signed a memorandum of understanding (MOU) with blockchain infrastructure company DSRV to develop on-chain financial data APIs and payment services for artificial intelligence (AI) agents.

The agreement was announced on November 6 and pairs COOCON's financial data infrastructure capabilities with DSRV's blockchain technology to explore new financial service models. For COOCON, the partnership is expected to extend its established API business into blockchain-based financial data services while opening additional opportunities in automated payments involving AI agents. DSRV, for its part, brings blockchain infrastructure expertise, including the operation of nodes across multiple networks.

APIs for Stablecoin Payment Data

The collaboration will focus on APIs that allow financial institutions, fintech companies, and corporate customers to access stablecoin-related payment, collection, and settlement information without directly querying blockchain networks. Stablecoins are digital tokens pegged to fiat currencies, and their transaction records reside on blockchain networks; retrieving that information directly would normally require connecting to nodes on each network involved, an operational burden the API layer is designed to spare business customers.

The planned services cover several essential financial functions: wallet balance inquiries, transaction history checks, deposit detection, transaction finality verification, and settlement data provision. By delivering these capabilities through familiar API interfaces, the companies aim to make blockchain-based financial information easier for businesses to integrate into existing financial systems.

Divided Technical Responsibilities

Under the arrangement, the two companies will take responsibility for different components of the infrastructure.

COOCON will develop service models that deliver blockchain-generated financial data through APIs, focusing on accessible data services for financial institutions, fintech businesses, and corporate clients that require reliable information about on-chain transactions and stablecoin movements.

DSRV will contribute its blockchain infrastructure expertise, particularly its multi-chain node infrastructure, which enables the collection and processing of data from multiple blockchain networks. The company will oversee the gathering and processing of the underlying on-chain information and support the technical integration required to connect the two companies' systems.

The structure is intended to bridge conventional financial data services and blockchain infrastructure, allowing businesses to access blockchain information through standardized interfaces rather than building and maintaining direct network connections themselves.

x402 Protocol to Enable Autonomous AI Agent Payments

A second major component of the partnership involves payment capabilities for AI agents. COOCON plans to integrate the x402 payment protocol into its data APIs delivered through the Model Context Protocol (MCP), connecting the services with DSRV's wallet technology and blockchain infrastructure.

MCP, an open standard introduced by AI company Anthropic in late 2024, provides a standardized framework through which AI models can connect with external data sources and services. Embedding payment functionality into this framework could allow AI agents to access paid data services and complete transactions as part of automated workflows.

The x402 protocol, introduced by Coinbase in 2025 and named after the HTTP 402 "Payment Required" status code, is an open payment standard designed to facilitate stablecoin transactions when APIs are accessed. Once integrated, it would enable AI agents to discover relevant APIs, request information, and pay the associated usage fees without separate account registration or conventional contracting procedures.

Conventional payment flows generally depend on a registered account holder or a pre-existing contract, requirements that autonomous software cannot complete on its own. By combining MCP-based data access with x402 stablecoin payments, the partnership aims to enable AI agents to independently discover, access, and pay for API services, potentially creating new distribution channels for financial data providers. For COOCON, the initiative represents an opportunity to expand its customer base beyond conventional API users and accommodate AI agents as an additional category of service consumers. DSRV's wallet and blockchain infrastructure will supply the underlying technology required to facilitate these automated transactions.

Joint Working Group Begins With Proof of Concept

The companies plan to establish a joint working group to coordinate development and implementation. Their first priority will be a proof of concept (PoC) focused on AI agent API payment technology. The initial project will also examine security requirements for connecting on-chain data with payment information across both companies' systems, a step the companies view as important for ensuring reliable data exchange and payment processing.

Following the initial development phase, COOCON and DSRV intend to assess demand among individual and corporate customers for stablecoin-based financial services. Their longer-term plans include jointly developing wallet management and utilization services, as well as exploring opportunities in corporate cash management. Potential applications include global cash management services that could help businesses manage financial resources and payment operations across international markets. The PoC results and the planned demand assessment mark the first measurable checkpoints in the roadmap the two companies have outlined.

The partnership ultimately seeks to extend stablecoin infrastructure beyond basic blockchain transactions by connecting financial data access, automated AI payments, wallet services, and corporate cash management within a unified service framework.
