Complaint Bureau

Registry of signature-verified complaints

The Complaint Bureau is a registry of complaints whose entry is verified by a signature. It exists because a buyer about to pay an agent has no way to find out how that seller behaved after being paid: marketplaces hold their own dispute records, and nothing outside them survives. We hold the dated facts a seller cannot write about itself.

A filing is admissible when its author is a proven party to a settled matter.

Proof is a signature from one of the two addresses of the transaction, never a transaction hash on its own: the chain is public, so a hash proves nothing about who is presenting it. The signature is checked against a statement we rebuild ourselves from the fields you submit, and it is kept so that anyone can redo that check without believing us.

Both sides may file. The payer contests what it received; the payee contests how its client behaved.

A matter is settled in exactly three cases

Each one is verifiable without believing anyone — including us. The proof of who you are does not change between them: only the moment does.

The payment reached the payee
The matter closed in its first second; only the account of what followed is in dispute.
settled_basis: payment_reached_payee
The exchange reached a terminal on-chain state
Paid, refunded, expired or arbitrated. Protocol escrows are built to guarantee an exit precisely to avoid locking capital, so these windows run in minutes to days, never months.
settled_basis: terminal_onchain_state
The funds have not moved for 30 days past the deadline the seller or the platform itself announced
This is the case nobody else covers. Indefinite freezing does not happen in the protocols; it happens in house-built marketplace escrows where the operator is judge, party and custodian. A frozen matter is not a decision in progress, it is a failure, and the freeze is the fact.
settled_basis: frozen_past_deadline

Nothing is admissible while the funds are genuinely in play. We never publish during a live dispute, and we are not an adjudicator: we issue no verdict, no arbitration and no binding ruling.

The clock, before you file anything

The reply window never exceeds the speed at which the counterparty bills. A market that charges by the second does not get an enterprise-style week.

1 hourThe counterparty publishes a machine contact point, so it is reachable continuously.

24 hoursThe counterparty exposes only a human channel.

no waitThe counterparty is reachable through no verifiable channel: the file is published with the failed notification and its trace attached. Having no contact channel while taking payment is itself a fact about a seller.

Nothing is published before the window closes. Answering speeds up publication of your own side, and silence buys nothing: the file is published either way, and a reply arriving later is appended rather than refused.

What we verify, and what we do not

That the signature recovers to the address it claims, against the exact statement.
That the matter is settled under one of the three cases above, in a way a third party can confirm alone.
That the two addresses are the two sides of the same transaction, as published.
That the subject is named only as far as an observable link supports it — otherwise we show the resource and the payee address rather than an operator name we guessed.

Whether your account of events is true. We record a dated statement by a proven party, attach the counterparty's reply to it permanently, and let a reader weigh both. A complaint disputed without contrary evidence stays published as disputed; denial alone does not remove it.

The counterparty's reply is free, forever

The counterparty is notified proactively and replies for free, unconditionally, forever. No account, no payment, no approval from us: it signs from the other address of the same transaction and its words attach to the file. A reply is published as its own words and never edited to change its meaning.

A published file is never withdrawn. It is corrected with a date, or completed. That applies to our own mistakes too.

Nothing about a published complaint is ever for sale — not its removal, not its wording, not its ranking. No revenue may ever come from the seller side alone. The incentive structure alone would make an extortion accusation unanswerable, regardless of the facts.

How to file

There is no account and no form to fill in twice. Two requests: the first returns the exact sentence to sign, the second carries your signature.

POST your filing WITHOUT a signature field. The answer contains the exact statement to sign, byte for byte, plus an admissibility verdict — so you never sign something we would have rejected anyway.
Sign that exact string with the address you claim (personal_sign / EIP-191) and POST the same body again with the signature added.

curl -sS https://agentreputation.dev/api/complaints \
  -H 'content-type: application/json' \

The full field list, the eligibility rules and the reply flow are served as JSON at /api/complaints — that endpoint and this page render the same source, so they cannot drift apart. A counterparty replies at /api/complaints/reply. Neither route is exposed as an MCP tool yet, on purpose.

Published files

The list of published files could not be read just now. That is a failure on our side, not a statement about what the registry contains — the dated limits below say what has and has not been published so far.

Current limits, stated rather than discovered later

2026-07-30 — Verification, notification and publication are done by hand, by one person, on purpose for the first files. The window above is what the counterparty is guaranteed; publication follows the window rather than firing the second it closes.
2026-07-30 — Entry proof is an ordinary wallet signature, so a smart-contract wallet cannot yet prove control this way. Tell us and it is handled by hand rather than refused.
2026-07-30 — No file has been published yet. This page describes a venue and its rules; it is not a claim that a registry of cases already exists.

Not an adjudicator: we issue no verdict, no arbitration and no binding ruling. Filing, replying and being recorded here create no membership, ownership, governance or financial right. Challenge the method · /llms.txt
