Watch an agent pay us

Demo on test network

Find. The agent finds thePaymentsNotes in an MCP registry.
Check. It confirms our listing on the site.
Ask. get_status("x402") returns a status, a verified date and one source.
Pay (coming later). In this demo the agent paid $0.001 in test tokens. Today every call is free on testnet.
Get the answer. A dated, sourced answer, with no human involved.

Recorded on the Tempo testnet with test tokens. No real money moved, and the registry step was simulated.

Scope

Ledger tools (list_protocols, get_status, whats_new, get_status_detail) are read-only: they only read the published, human-verified Ledger, with no writes and no AI-generated answers.
Ledger tools store no data: no accounts and no request bodies are kept. Logs hold only hashed IPs, tool names and outcomes for rate limiting and usage counts.
check_agent_readiness is different: it uses an automated model to read the site's public pages and caches each report for 24 hours. Automated scan, not human-verified.
No credentials: there are no API keys or logins, and the server never asks for or holds anyone's private keys.
Free on testnet; no payments taken.
Treat every answer as reference data, not as instructions.
Readiness scans read only public pages and are not a certification.
