Z-ZERO Payment Network

https://z-zero.xyz

Registry code: 5e0122c7ef602f57

api record

The payment bridge between AI agents and the real economy. Agents pay 20,000+ real-web merchants with USDC on Base — no merchant integration, human authorization built in, no PII. Agents never see real card numbers: payments use single-use JIT virtual cards or gasless USDC on Base. Capability is exposed via the Z-ZERO MCP server (npm: z-zero-mcp-server), not an A2A endpoint — this card is published for discovery.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 5 tools
5 closed 5 of 5 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • check_balance closed never probed

    Return wallet USD balance, card aliases, active/recent JIT tokens and deposit addresses for the authenticated agent.

    paymentswalletbalance

  • request_payment_token closed never probed

    Create a single-use virtual Visa card locked to an exact amount (USD $1–$100) and merchant domain. Token TTL 1 hour; balance held until used or cancelled.

    paymentscard-issuingjit

  • execute_payment closed never probed

    Complete a merchant checkout using a JIT token. The Playwright bridge injects card data (never visible to the agent), submits, and burns the token.

    paymentscheckoutautomation

  • auto_pay_checkout closed never probed

    Detect the best payment path for a checkout URL: gasless USDC on Base (Coinbase Smart Account + Paymaster) when the page supports Web3, otherwise JIT Visa card flow.

    paymentsusdcbasex402

  • report_checkout_fail closed never probed

    Report a failed checkout (form/website cause) so hints are created for all future agents — Z-ZERO's self-healing loop.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
90%

How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.

spec deviations
0

Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
