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.

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

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

Create a payment link for an evidence extract: everything this archive recorded on a domain, as one verifiable document (every observed day, every file type, both witnesses, with the seals and verification instructions). One to twenty domains. A domain this archive never observed is refused by name before the link is created, because there would be nothing to deliver; use check_coverage first. Thi

Create a payment link for the daily observation of domains, as a yearly or monthly subscription: from admission, within five working days of payment, two independent witnesses record each domain every day in full (homepage and the machine-readable files), seal each day and anchor it externally; the admission is entered in the public record. The customer pays for the measurement, not for a document

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.
