Is holdmark live?

Yes — it answered the hub's last check (checked 3h ago). It answered 100% of checks over the last 30 days.

Is holdmark free to use?

Yes — the hub reached it with no key and no payment.

What tools does holdmark have?

3 tools: get_store, how_holdmark_works, find_stores.

Is holdmark 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.

• find_stores open 3h ago

  List the online stores in the holdmark registry, with a summary of their published facts. Each store publishes the same facts under the same rules: whether it delivers its orders (checked with the carrier) and whether it refunds money (checked with the payment processor). holdmark does not rank stores and has no score, so compare them yourself by whatever the person actually cares about. The registry only contains stores that connected their data. A store missing from it has not been judged.

• get_store unknown 3h ago

  Read the full holdmark record for one store, by its domain. Figures are rounded against the merchant, order volume is published in bands rather than exact numbers, and every figure carries the period it covers and the source it came from. A fact with no data answers "not_measured" with its reason, never "no". If the domain is not in the registry you get a plain answer saying so, which is not a verdict about that store.

• how_holdmark_works unknown never probed

  How every figure in the registry is calculated, what the words mean, and above all what holdmark does NOT measure. Read this before drawing a conclusion from any record: it is what stops a figure being read as something it is not.
