Values you fill in

Common questions

Is agentic-pay safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: BTC_WIF, ETH_PRIVATE_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

Agentic Pay

A cross-platform payment engine that lets third-party AI agents send and receive payments over seven crypto rails: BTC, ETH, USDT, USDC, XRP, XMR, ZEC.

One Node.js core runs unmodified on Linux, Windows, and macOS. The same backend is reachable from iOS and Android via an installable Progressive Web App (PWA) — there is no separate native mobile codebase to maintain.

Every send, from any surface, passes through core/limits.js (per-agent spend caps + human-confirmation floor) and core/ledger.js (idempotency, so a retried tool call can never double-pay).

Quick start (any OS with Node.js 18+)

git clone <this repo>          # or unzip the delivered archive

cd agentic-pay npm install

cp config/.env.example .env cp config/config.example.json config/config.json

edit both files — see docs/SETUP_ .md for exact values per rail

npm run start:rest # REST API on :8787 npm run start:web # PWA on :8788 (optional, for mobile/browser access) npm run start:mcp # MCP stdio server (for Claude Desktop / Claude Code) node cli/index.js rails # sanity check from the terminal

Start on testnets first. Every rail's example config defaults to a testnet or requires you to explicitly fill in mainnet values — this is intentional. Do not point real funds at this system until you've reviewed core/limits.js and set spend caps you're comfortable with.

Hosted (custodial) — skip the setup

Don't want to run your own node? Aumnium operates a hosted instance at https://api.aumnium.tech — deposit USDC, get a spendable custodial balance, and start sending across all seven rails without installing or funding anything yourself.

This is a different trust model than the self-hosted instructions above: your funds sit in a pooled wallet operated by Aumnium (not your own keys), and each send is charged a 1% fee plus network cost, deducted from your balance. The self-hosted path above remains fully non-custodial; this hosted path trades that for convenience.

# 1. Get your deposit address

curl -H "x-api-key: YOUR_KEY" https://api.aumnium.tech/v1/deposit/address

2. Send USDC to that address on Ethereum mainnet

3. Claim your deposit once it confirms

curl -X POST -H "x-api-key: YOUR_KEY" -H "Content-Type: application/json" \ -d \'{"txHash":"0x..."}\' \ https://api.aumnium.tech/v1/deposit/claim

4. Send payments (billed per-call via x402, USDC on Base)

curl -X POST -H "x-api-key: YOUR_KEY" -H "Content-Type: application/json" \ -d \'{"asset":"USDC","to":"0x...","amount":1,"idempotencyKey":"unique-key"}\' \ https://api.aumnium.tech/v1/send

What's genuinely production-ready here vs. what's a starting point

Production-shaped: the policy engine (per-tx cap, daily cap, confirmation floor, address allowlisting), the idempotent ledger, and the unified rail interface.
Starting point, needs hardening for real money at scale: the JSON-file ledger (swap for a real database under load), the static USD price table (wire in a live price feed), and key storage (move from .env to an OS keychain or HSM/KMS for anything beyond development — see core/keystore.js for the extension point).
