RelAI is the payment and execution layer for AI agents

AI agents can access APIs and pay per request - without wallets, gas, or human interaction.

Payments happen automatically in real time.

x402 payment flow

The Problem

AI agents can't pay for anything.

They can think, decide, and act - but they can't transact.

No wallets or native identity

No way to handle gas fees

No standard for API payments

Subscriptions don't work for machines

The result

Software still depends on humans
to complete transactions.

The Solution

RelAI enables AI agents to pay for services autonomously

From human checkout to autonomous payments.

Pay per API call using HTTP 402
Execute payments automatically
Fund agents without wallets
Monetize APIs instantly

From human checkout to agent economy

in one system
How it works

Five steps. One system.

01
Fund

Add funds using fiat or crypto

02
Lock

Funds are secured in a vault

03
Assign

Agents receive spend permissions

04
Execute

Agents call APIs and pay automatically

05
Settle

Payments complete instantly with zero gas

The full payment stack for agents

Pay per request

Charge for every API call - no subscriptions required

Payment codes

Pre-authorized payments that can be executed anytime

Agent budgets

Define exactly how much an agent can spend

Zero gas execution

All transactions are sponsored and instant

A new payment primitive

RelAI separates payment authorization from execution.

Funds are locked in a vault.

Agents receive permissions to spend them.

Execution happens later, automatically.

Agents don't hold money -

they hold permissions to spend it.

Built for real-world use cases

AI agents

Autonomous agents accessing paid services

API monetization
