Ripple Launches XRPL AI Payments, Celo Opens Stablecoin Micropayments, and Visa Connects Agent Commerce

Ripple and Celo opened new payment tools for AI agents, x402 gained neutral governance, and Visa advanced card and stablecoin infrastructure for autonomous commerce.

Ripple Launches XRPL AI Starter Kit and Enables x402 Payments in XRP and RLUSD

Ripple launched an XRPL AI Starter Kit that lets software agents pay for APIs, computing power, and other digital services in XRP or RLUSD through the x402 protocol. The June 9 release gives developers a ready-made route from an AI application to a wallet, an HTTP payment request, and settlement on the XRP Ledger.

The official Ripple announcement says the package includes an MCP server for XRPL documentation, agent wallet and payment skills, and x402 support contributed by infrastructure provider t54. XRPL's built-in decentralized exchange can also convert between assets during a payment, allowing a service to request one currency while an agent holds another.

XRPL's technical x402 guide documents XRP and RLUSD as supported payment assets and shows the same integration moving from testnet to mainnet by changing the network, facilitator, and wallet configuration. That reduces the amount of custom payment logic developers must build before an agent can buy a digital resource.

For adoption, the important change is that a machine can now become a paying customer without being handed a conventional checkout page. The initial market is likely to be machine-readable services—data feeds, inference, storage, and compute—but the same wallet and authorization patterns can later connect agents to AI crypto services and merchant systems.

Celo Opens an x402 Gateway and Lets AI Agents Pay APIs With Stablecoins

Celo opened a hosted x402 gateway and added tools that let AI agents pay for online resources in stablecoins, with settlement designed for low-value, high-frequency transactions. Its implementation supports USDC, USDT, and USDm, while fee abstraction allows an agent to cover network costs in the same stablecoin used for the purchase.

The Celo developer documentation presents x402 as a payment layer for AI inference, pay-per-article access, datasets, and other API-delivered products. A server responds to an unpaid request with HTTP status 402 and payment instructions; the agent signs the payment, a facilitator verifies and settles it, and the server then releases the requested resource.

In its Season 2 retrospective, the Celo Foundation said it launched the free hosted gateway at x402.celo.org. It also described an experimental tool called cPay that can combine payment with identity, age, or sanctions-screening proofs in the same request. The system was available on testnet and designed to work with the Model Context Protocol used by AI applications.

Stablecoin support gives these payments a familiar unit of account and avoids exposing a service provider to the price movement of a volatile token. It also creates a new software-native use case for USDC and USDT: agents paying for small digital inputs automatically instead of a person managing subscriptions or prepaid balances.

Linux Foundation Activates the x402 Foundation and Moves Agent Payments to Open Governance

The Linux Foundation announced the operational launch of the x402 Foundation on July 14, placing the payment protocol under open, vendor-neutral governance after Coinbase completed its contribution of the technology. The foundation began operations with 40 members spanning payments, cloud infrastructure, commerce, stablecoins, and blockchain networks.

According to the Linux Foundation announcement, participants include Visa, Mastercard, Stripe, Circle, AWS, Google, Shopify, Ripple, and other infrastructure providers. The project is intended to standardize internet-native payments for AI agents and applications while remaining compatible with both card and stablecoin settlement.

The open-source x402 specification uses the web's existing HTTP 402 “Payment Required” response. A resource server returns payment requirements, the client signs a payment, a facilitator verifies and settles it, and the server responds with the requested resource. This puts price discovery, authorization, and delivery inside the same machine-to-machine exchange.

Neutral governance matters because agent payments will cross wallets, networks, facilitators, and merchants controlled by different companies. A common protocol can reduce one-off integrations for crypto payment gateways and make it easier for services to accept multiple settlement methods without changing how an AI agent requests access.

Visa Connects Card and Stablecoin Rails and Adds Trust Controls for Agent Commerce

Visa published a joint report with Artemis that maps cards and stablecoins as complementary payment rails for AI agents, while separately building controls to identify agents and score their transactions. The company expects cards to serve established merchant networks and stablecoins to handle machine-native micropayments and programmable settlement.

The Visa and Artemis report, updated July 14, uses live blockchain data to examine how agents could book travel, replenish inventory, or buy data and computing resources. It says newer card-oriented agent protocols are adding stablecoin support, while projects such as the Machine Payments Protocol can support both onchain and fiat settlement. Visa's stated direction is convergence rather than a winner-takes-all contest between the two rails.

Visa also announced Agent Score, Agentic Directory, and a command-line payment proof of concept in June. The command-line tool lets an AI agent pay for digital services with Visa tokenized credentials. Agent Score is intended to help issuers assess agent-initiated transactions, while the directory gives merchants a way to identify trusted agents. Visa reported an annualized stablecoin settlement run rate of about $7 billion as of March 2026 and said 160 stablecoin-linked card programs were live or in development.

These releases move agent commerce beyond demonstrations toward interoperable payment, identity, and risk infrastructure. Merchants are not yet receiving an uncontrolled wave of autonomous buyers, but the building blocks now connect web requests, crypto wallets, stablecoin settlement, cards, and compliance. Businesses preparing to accept crypto payments may therefore need to treat software agents as a distinct customer channel, with spending limits and verification rules built into the payment flow.
