Payment Verification

Verification for agent payments

Financial actions initiated by autonomous systems require more than a transaction ID. Agent Commerce provides an evidence layer - structured, retrievable, and where applicable cryptographically provable records attached to every action in the workflow.

The evidence layer

When an AI agent triggers a financial action, the execution event contains a reference to what happened. Verification answers the deeper questions: who or what authorized the action, what constraints governed it, what provider processed it, and what record was retained.

Agent Commerce extends CertifiedData's verification model - used for synthetic datasets and AI artifacts - to financial workflow events.

Verification payload shape

The verification surface returns a structured response that lets machines confirm integrity, issuer authenticity, and overall validity without relying on private platform state. The full field-level reference lives on the deeper payment verification page.

What verification covers

→
Authorization trail - who or what initiated the action and under what identity
→
Policy record - what spend cap, approval rule, or policy constraint was evaluated and its outcome
→
Execution reference - which provider processed the action and the provider's transaction reference
→
Evidence artifact - a structured record, and where implemented, a cryptographically signed provenance artifact

Governance use cases

Enterprise audit

Internal audit teams can retrieve full event history for any agent-initiated financial action - authorization, execution, approval decision, outcome - without relying solely on provider statements.

Compliance review

Organizations subject to financial controls can demonstrate that spending policies were enforced programmatically, with records to match each action to its governing rule.

Agent accountability

Autonomous systems that take economic actions leave a provenance trail that supports post-hoc review, dispute resolution, and policy tuning.

Regulatory readiness

Structured event records and verifiable artifacts support audit requests without reconstructing history from scattered logs.

How verification works

Agent Commerce records every workflow event with full context at time of action.

Events are retrievable by transaction ID via the API at any time after the action.

Where applicable, a signed provenance artifact is issued for the completed action.

The artifact can be independently verified using CertifiedData's verification infrastructure.

Verification returns: record integrity, issuer, timestamp, and provenance chain.

Proof surfaces

Verification endpoint

GET /api/payments/verify/:receiptId

Public endpoint for checking receipt integrity, signature validity, and overall verification status.

Published public key

GET /.well-known/certifieddata-public-key.pem

Public key surface used by external systems to validate Ed25519 signatures independently.

Relationship to CertifiedData verification

The same verification infrastructure that certifies synthetic datasets produces provenance records for Agent Commerce financial events. This connects agent financial actions to the broader CertifiedData trust layer - not as a separate product but as an extension of the same evidence model.
