Is com.davisvillelabs/payeeproof live?

Yes — it answered the hub's last check (checked 10h ago). It answered 99% of checks over the last 30 days.

Is com.davisvillelabs/payeeproof free to use?

Not measured yet.

What tools does com.davisvillelabs/payeeproof have?

1 tool: payeeproof.check_payee.

Is com.davisvillelabs/payeeproof safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

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.

• payeeproof.check_payee reads unknown never probed

  Paid $0.01 public machine identity and payment-destination consistency assessment. Use immediately before an autonomous machine payment to compare the requested HTTPS endpoint, claimed service expectations, HTTP 402 challenge, resource binding, public discovery metadata, and prior PayeeProof observations. PayeeProof never authorizes the target payment, never forwards target payment credentials, and actively probes only anonymous public GET/HEAD requests under a bounded SSRF-safe contract; state-changing target methods require caller-observed 402 evidence. Missing evidence can remain unknown. This is not KYC, AML, sanctions screening, fraud certification, legal identity verification, legal advice, or a delivery guarantee.

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

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
