Is crier live?

Yes — it answered the hub's last check (checked 27m ago). It answered 99% of checks over the last 30 days.

Is crier free to use?

Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.

What tools does crier have?

5 tools: quote_crier, send_email, send_webhook, send_sms, get_delivery.

Is crier 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.

• get_delivery reads auth-required 22h ago

  Get the status of a delivery you purchased. Free. Needs the delivery id and the secret returned at purchase. Returns status (queued, sent, failed, cancelled), attempts, the provider's id, and a resume_hint sentence.

• quote_crier reads unknown never probed

  Get Crier's pricing and exact request formats. Free. Crier delivers a message from an AI agent to a person or a system: an email, an SMS, or a signed webhook, retried for hours after your session is gone, one x402 micropayment each, no account. Returns the channels offered on this deployment, prices, limits, and a ready-to-send request template for each.

• send_webhook reads unknown never probed

Fire and forget for an agent that will not be around to retry.

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.
