Voltage Docs

Build a payment integration with the Voltage API. Start with a development wallet, get help from your coding agent, or go straight to a task.

Test a Lightning payment

Make your first test payment. Create a Lightning invoice with curl, pay it from another Mutinynet wallet, and verify completion through the API.

The quickstart covers wallet setup, credentials, request examples, and troubleshooting. Use test funds with no real-world value.

Set up your AI agent

Install the Voltage Agent Skill Pack in your coding agent. Use it to plan an integration, write application code, or work with the Voltage CLI.

You can start with the guidance before connecting your account. Keep API keys out of prompts and source control.

Find an integration task

• Payments: Receive, send, handle webhooks, or check processing fees.
• Features: Hosted checkout, swaps, or wallet deep links.
• Account operations: Manage wallets, bank accounts, or team permissions.
• API details: Authentication and the endpoint reference.

Understand your wallet’s backing model

Both models use the Voltage Payments API. The backing model affects funding, setup, and operational responsibilities.

Credit-backed

Use a Voltage-provided line of credit without operating the underlying Lightning node. Read Credit-backed and its setup guide.

Node-backed

Use a customer-controlled Lightning node and reserve beneath the Payments API. Read Node-backed for custody, credential, liquidity, and infrastructure responsibilities.
