For AI agents & LLMs
Tell your assistant where the money goes. It calls Shieldz over MCP and hands back a live payment link, an embed, and a QR. No dashboard. No API key. No account.
No pre-issued key needed. Add the server, and the agent can monetize with nothing but an address. Power users still drop in a SHIELDZ_API_KEY for the full merchant tools.
// no API key, identity is the settlement address create_payment_link({ address: "0x71C…3F2", chain: "base", asset: "USDC", amount_usd: 49, memo: "Pro plan" }) → { pay_url: "https://shieldz.cash/p/8kQ2x", qr_url: "…/p/8kQ2x.png", embed: "<script src=…>", manage_url: "…/a/cap_8kQ2x" }
Any tool that can build a URL, an agent with only fetch, a browser, a link pasted into a chat, can mint a payment method. No client, no JSON body, no key. The response carries the payment URL and a manage_token claim code.
# Reusable tip jar, the payer picks the amount GET https://shieldz.cash/api/v1/tip-jars?to=0xWALLET&title=Buy+me+a+coffee&amounts=1,5,20 # Fixed-amount payment link GET https://shieldz.cash/api/v1/links?to=0xWALLET&amount=25&chain=BASE&asset=USDC → { url: "https://shieldz.cash/tip/…", manage_token: "…" }
Add &accent=%237c3aed, &image= and social links to white-label the page in your own color and logo, the accent even carries through to the checkout. Tip jars are idempotent per wallet, and to / amount are hand-writable aliases. Full params in the HTTP reference →
Pass a single accent hex, a logo and a brand name. It themes the payment page, the coin picker, and every checkout screen the payer sees, no dashboard, no signup. Same three cards below, three URLs.
Try it in one line: /api/v1/tip-jars?to=0xWALLET&brand=Acme+Store&accent=%237c3aed&logo=https://you.com/logo.png or build it in the no-code tip-jar tool →
Shieldz ships as a single MCP server. Drop it into any autonomous agent and it can take payments, no key handed over, nothing custodial.






↳ Any MCP-capable agent works, Claude, Cursor, AutoGen and the rest included.
OpenClaw runs on a heartbeat and lives in your chat apps. With the Shieldz skill it spins up a payment link from a single message, keyless, non-custodial, then reports what came in on its next cycle.



Anyone can create a link, so every link passes the same checks, and because nothing is custodial, the worst case is never lost funds.
Creation also returns a capability-token view: a clean page a human can open with no login, and a JSON twin an agent can fetch. The token in the URL is the access.
