AiFi stablecoin payments for AI agents, machines, and connected devices

AiFi means Agentic Finance: payment infrastructure that lets autonomous software and hardware pay for and unlock services through ModelGlue x402. Create USDC requirements, verify payment evidence, authorize actions, and retain receipts without custodial accounts.

AiFi use cases

Agentic Finance at the moment software or hardware acts

Stablecoin Merchant explains and onboards the AiFi use case. ModelGlue x402 handles payment requirements, verification, receipts, and runtime configuration.

AiFi for autonomous agents

Let AI agents and autonomous applications pay for models, tools, data, compute, content, and digital actions as they are requested.

APIs and MCP servers

Protect API calls, MCP tools, premium endpoints, and machine-readable resources with x402 payment requirements.

Agent-to-service payments

Give autonomous agents a verifiable USDC payment path for paid actions and services.

Machines and connected devices

Authorize vending, kiosk, rental, robot, appliance, and connected-hardware actions after payment verification.

Automated commerce

Support machine-triggered purchases, automated fulfillment, and usage-based services across software and connected hardware.

Models, data, and compute

Charge per request for inference, datasets, reports, analysis, processing, and other metered resources.

How AiFi works

One Agentic Finance entry point. One ModelGlue x402 layer.

1

Define the paid machine action

Choose the AI tool, API request, MCP operation, digital resource, or device function that requires payment.

2

Return an x402 requirement

Your service uses ModelGlue x402 to define the USDC amount, receiving address, identifiers, and payment conditions.

3

Let the payer software respond

An agent, application, machine, device, or compatible wallet completes the required USDC payment.

4

Verify and authorize

ModelGlue verifies the payment evidence so your system can release access, execute the action, and retain a receipt.
