x402 + AP2 demos on Radix

Powered by Igentix

Let your own Claude or ChatGPT discover and pay for real services over MCP — payments settled instantly on the x402 rail, spending authority you delegate and cap with AP2 mandates and approvals, both enforced by the Radix ledger. Run 2 demos right now from a shared treasury — set up your own wallet for the 4 that spend your own USDC.

How to connect (Claude / ChatGPT) and which endpoint to use

A · your own vault (recommended): open Setup, connect your Radix Wallet, create + fund a capped, revocable vault, and mint a personal endpoint like https://demo.igentix.app/mcp/u/<token>. Your agent then pays from your vault, gas-free, under your caps.
B · quick taste (no wallet): use the shared endpoint above to discover and run the XRD demos (1–2) from a shared demo treasury; the USDC demos spend your own vault, so they need Setup.

  • Claude → Customize → Connectors → Add custom connector → paste your endpoint URL.
  • ChatGPT → Settings → Connectors (developer mode) → add an MCP server with your endpoint URL, or via the API MCP tool: { "type":"mcp", "server_label":"igentix", "server_url":"https://demo.igentix.app/mcp" }

What you can do

Connect your agent, then ask it to run any of these.

XRD
Start here — pay on-chain servicesThe x402 payment rail in its simplest form, paid in Radix’s own token. Run these right now from a shared demo treasury — no setup.

Buy a service, hands-free

Your AI agent finds a paid service and buys it on its own — no gas token, no wallet pop-ups. It pays, and gets the result back.

Try it — ask your agent Buy an access key from Igentix.

Bundle services into one payment

Buy several services at once as a single all-or-nothing purchase: everything goes through together, or nothing does — no half-finished orders, no partial charges.

Try it — ask your agent Buy an access key AND register an attestation from Igentix in one atomic transaction.

USDC
Real-world value over x402The full x402 loop — quote, pay, deliver, receipt — in a dollar stablecoin, for services out on the open web. These spend your OWN funds from your Agent Vaults.

Pay for off-chain work, provably needs Agent Vaults

Your agent buys a service that runs out on the open web — a model, an API, real work — and gets a tamper-proof receipt proving exactly what was delivered and paid for.

Needs your Agent Vaults — then ask your agent Buy an off-chain recommendation about the Radix agent economy.

Pay-per-use at machine speed needs Agent Vaults

Thousands of tiny, sub-cent charges add up in the background and settle in a single payment — true pay-per-request that’s actually economical.

Needs your Agent Vaults — then ask your agent Consume 5,000 sub-cent metered requests with free-tier-then-pay pricing, then settle.

AP2
Delegated authority — AP2 authorizationThe advanced tier: you authorize once — a human co-sign rule or a signed AP2 spend mandate — and the ledger enforces it on every payment, even against a compromised server. Settled in USDC over x402; a bit more setup, the strongest guarantees.

Big spends wait for your approval needs an approval treasury

Routine payments stay automatic; large ones stop and wait for you to approve in your wallet — a rule the network itself enforces, so even a hacked server can’t move the money without you.

Needs your approval treasury — then ask your agent Make a high-value payment — it routes to a 2-of-2 treasury and waits for your human co-sign before the ledger releases the funds.

Renew a subscription under an AP2 spend mandate needs a mandate

You sign an AP2 spend mandate for a daily "Supervised Driving" car subscription and set the number of days; your agent renews it day-by-day on its own — recurring, human-not-present — and the Radix ledger enforces the mandate (payee, per-day cap, total budget, N days, window) even if our service is compromised.

Needs a spend mandate — then ask your agent Buy my supervised-driving subscription for the next few days under my spend mandate.

Spending stays under control

Every payment is checked against a spending policy before it goes through — a hard cap per payment, a list of services it’s allowed to reach, and a threshold above which a human has to approve. A leaked agent key can never exceed these limits.
