MachineWitness

Answer whether this archive observes a given domain, from which sealed day onward, which machine-readable files it requests, and at what cadence. Returns metadata only — never the contents of any file, and never an assessment of the domain or its operator. 'Not observed' is a statement about this archive, not about the domain: most of the web is not observed.

  "properties": {
    "domain": {
      "type": "string",

    }
  },
  "required": [
    "domain"
  ]
}

Suggest that a domain be observed. This is a request, not an instruction: admission follows documented criteria (a connection to the European Union, publicly served machine-readable files) and is decided by the operator. The answer is always 'received' with 'guarantee: none' — it creates no obligation to observe the domain, no timeline, and no assurance that it will be added. A reason is required and is read by a person.

Create a payment link for a point-in-time record: both witnesses fetch the named addresses, take a full-page picture of each, and give each capture its own qualified electronic time-stamp. Up to twenty public addresses, all on the same domain. Before the link is created, every address is checked at no charge: a public domain name, not on the stop list, robots.txt allows our crawler, and it answers without a login; refused addresses are named with the reason. This call charges nothing. The capture starts only after a person has paid on the returned page; the record is then delivered by e-mail, and a second e-mail follows after the night's seal. Only addresses are asked for, never a purpose. Fees: https://machinewitness.eu/services

Where a point-in-time record stands, by its reference (MW-K-…): awaiting payment, queued, capturing, first delivery sent, complete. Per witness: waiting, capturing, captured, failed or refused. Never returns the e-mail address, the addresses ordered or anything else about the customer.
