For builders

Infrastructure for programmable commerce.

Build payments for people, businesses, applications, and intelligent agents through one coordinated economic runtime.

Start with your use case

Choose what you are building.

The Runtime stays consistent while the capabilities, controls, and economic flow adapt to your product.

Autonomous

AI agent

Give intelligent software controlled access to wallets, x402 settlement, policy, verification, and deterministic receipts.

Integration architecture

Submit intent. Let the Runtime coordinate execution.

Your application should not need to rebuild identity, compliance, risk, policy, settlement, retries, telemetry, and receipt generation for every new payment rail.

Application

A wallet, marketplace, merchant platform, service, or autonomous agent initiates an economic action.

SDK or API

The integration submits payment intent and the context required by the Runtime.

Zephyon Runtime

The Runtime coordinates identity, compliance, risk, policy, trust, settlement, and telemetry.

Settlement adapter

A rail-specific adapter translates the approved event into network execution.

Deterministic receipt

The final result and its execution timeline return through one consistent record.

Developer interface

One payment intent. Multiple integration paths.

The public SDK surface is still being finalized, but the intended developer model is direct: submit economic intent, receive a coordinated result, and preserve the receipt.

Runtime payment example

import { ZephyonClient } from "@zephyon/runtime";

const zephyon = new ZephyonClient({
  environment: "devnet",
});

const payment = await zephyon.payments.create({
  amount: "25.00",
  currency: "USDC",
  recipient: "merchant_zephi",
  purpose: "business",
});

console.log(payment.receipt);
console.log(payment.timeline);

Illustrative developer interface. Package names and public production endpoints will be finalized before general availability.

Runtime capabilities

Payment infrastructure should be composable.

Use the full runtime path or integrate the capabilities your product needs as the public SDK and API surface expands.

Identity

Resolve people, accounts, merchants, applications, and autonomous agents.

Compliance

Coordinate KYC, KYB, sanctions, monitoring, and jurisdiction controls.

Risk

Evaluate transaction context, runtime signals, confidence, and limits.

Policy

Apply platform, merchant, organizational, account, and agent rules.

Settlement

Coordinate payment rails through a consistent execution interface.

Resilience

Handle endpoint health, retryable errors, failover, and bounded recovery.

Telemetry

Observe execution stages, timing, decisions, retries, and settlement outcomes.

Receipts

Preserve deterministic records for verification and downstream systems.

Runtime execution

Watch a payment think.

A Zephyon payment is not blindly forwarded to a network. The Runtime coordinates a controlled decision path before value moves and preserves the result afterward.

Runtime execution demonstration

Watch the Runtime coordinate a payment decision.

Payment request

Economic intent received.

Identity resolved

Participants and account context established.

Compliance approved

Required controls completed.

Risk acceptable

Runtime signals remain within policy.

Policy satisfied

Payment rules permit execution.

Settlement selected

The Runtime chooses the appropriate rail.

Transaction submitted

Settlement moves to the network adapter.

Receipt generated

Execution evidence is preserved.

Verified

The economic event reaches completion.

Awaiting payment

Demonstration only
