Registry code: 6cfd9fab126058cc
Kairostamp is a pay-per-call web evidence API for autonomous agents. Each endpoint fetches one public http/https URL server-side and returns a time-stamped, tamper-evident result. Payment is x402 exact USDC on Base — no accounts, no API keys. Use `list_endpoints` to see what is available, `get_payment_terms` for the payment details, and `plan_call` to get the exact request for a given endpoint and target URL. These tools return public catalog data only; the paid work happens when you make the planned HTTP request and settle the 402 challenge.

last good check
of 1 tools
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.

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.
snapshot_preflight unknown never probed
Free eligibility and price check for a target URL. Performs no outbound fetch and stores nothing.
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.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
