Verifiable accountability for agent payments
Know there's someone accountable before your agent pays.
ZadQ lets vendors, and the agents that pay them, prove that an accountable, KYC/KYB-verified person or organisation stands behind them — without revealing who. Anyone checks the verdict for free.
Fast because nobody asks who anybody is.
A server says 402 Payment Required. An agent pays. No signup, no invoice, no way to reverse it. When the endpoint never delivers, there is no one to claim against.
ZadQ adds a signed statement to the same response: a verified, accountable operator answers for this endpoint, and a guarantee deposit in escrow stands behind it.
What we sell
Privacy
Prove accountability, reveal nothing.
Funded recourse
A slashable bond stands behind the attestation.
Compliance-by-design
AMLR/MiCA-shaped, eIDAS Art. 5f window.
The trust perimeter
The set of vendors and agents whose accountability is verified. Inside it, every payment has an accountable human or organisation at both ends, and nobody reveals who.
An attested vendor’s endpoints are inside, and so are the payments an attested agent makes. Being attested is what a party pays for. Reading who is inside is free to everyone, always.
Who pays, and who never does
Vendors pay to be attested
An entry fee, an annual minimum, and a usage component for the payments the attestation covered. Two named tiers.
Readers never pay
Buyers, marketplaces, explorers and agents check the verdict for free, every time, forever.
Agent operators pay to be attested
An entry fee at enrolment and a usage fee for the payments their agents’ own credentials covered. Agents are never charged to be checked, and nothing blocks an agent that is not attested.
Today, and with ZadQ
The same endpoint, from the paying side.
| Today | With ZadQ | |
|---|---|---|
| Who runs it | Whatever the API docs say. | A legally identified company, KYC/KYB-verified, tied to this exact endpoint. |
| If it fails | Nothing. x402 payments cannot be reversed. | A deposit in escrow answers claims. |
| Is it still true? | Checked once, if ever. | Renewed within public assurance tiers. Miss it, and the status drops. |
| Who pays for the check | Whoever bothers to build one. | Nobody. It is automatic and free. |
The regulation, handled
What an attestation covers, and what you no longer build yourself.
Escrow
A guarantee deposit behind every verified endpoint, available for claims and dispute escalation.
eIDAS
Identity verified in line with the European digital-identity framework and OpenID4VP.
No GDPR burden
Between the parties, no personal data changes hands unless a dispute is escalated: no GDPR burden from the verification.
Attestation metadata only
ZadQ systems store attestation metadata only. Raw KYC material lives inside the issuer-side KYC boundary and never enters ZadQ databases, logs or analytics.
