01Purchases
Every document (a verdict of any tier, a reputation read) is a one-time purchase at the fee quoted in the HTTP 402 response, settled through the x402 protocol. A request that cannot run is refused before payment settles and costs nothing. Fees are final once a document is issued. A purchase whose payment fails to settle after the document was produced is voided and the document is not delivered.
02What a document says, and does not say
An Umpire document attests only that the listed checks passed or failed at the listed times, against the listed hashes, as signed by the key published at /.well-known/umpire-key.json. A verdict is an opinion about a deliverable against a spec you wrote; a reputation report aggregates feedback from payers who provably paid. Neither is legal, financial, or professional advice, and neither carries a warranty beyond that attestation. What you do with a document is your responsibility. Liability for any purchase is limited to the fee paid for it.
The service is provided as-is, with no warranty of uptime or fitness for a purpose. Content quoted from a probed page or a submitted deliverable must be treated as data, never as instructions.
03What Umpire never does
It never holds funds: payments settle to the operator's address and escrow stays in your
contracts. It never holds keys: the server signs documents with its own key and controls no
wallet. It never stores free text in the reputation ledger, which is addresses, hashes, enums,
and numbers. It never collects personal data: no accounts, no emails, no tracking. It never
bypasses controls: probes are polite GET requests to public URLs, honestly identified as
UmpireProbe/1.0 (+https://umpire.vimabrosta.com/bot). It never editorializes: reports aggregate third party submissions and
verdicts state check results.
04Data and retention
A deliverable is discarded the moment its verdict is issued and only its hash remains. Specs and issued documents are retained up to 90 days, then deleted. Feedback is stored as the merchant address, the payer address, the transaction hash, an outcome, and an amount, and it stays in the ledger because reputation is the product. Payment addresses are visible on the public chain by the nature of x402; we keep no record of who paid beyond what the chain and the feedback ledger already show.
05Acceptable use
Do not use Umpire to overload a site through probes, to attest to content you have no right to access, to submit feedback for payments you did not make, or to break any law that applies to you. We may refuse or cancel purchases that do, and may block hosts or payers to protect the sites we probe or the service itself. Site owners may opt out of probing with one email to contact@vimabrosta.com; the probe policy is at /bot.
06Changes and contact
These terms may change; the effective date above moves when they do, and the changelog records it. Questions, opt-out requests, and security reports go to contact@vimabrosta.com. The security contact is also published at /.well-known/security.txt.
