Exact use case

A lost shipment or duplicated charge reaches multiple teams and every retry risks moving money twice.

Input you provide

Customer-supplied order lines, payment captures and refunds, shipment status, inventory state, and exception identifiers.

Output you receive

Classified exceptions, a refund cap, ordered actions, idempotency keys, and a receipt that makes replay safe.

What the API does

Derives a remedy plan from supplied commerce state and makes its replay semantics explicit.

Authenticated first value

A successful authenticated POST /v1/exceptions that returns a bounded, ordered, idempotent action plan.

Response
Run the demo to see the API response.

A successful response demonstrates the bounded classification or calculation shown here. It is not evidence of a deployed connector, autonomous external action, customer outcome, or commercial performance.

Capability boundary

What this page does not promise

It does not execute refunds, move money, or provide a live Shopify, Square, marketplace, OMS, or ERP integration.

  • The demo qualifies the transformation only; account verification, key creation, and a successful authenticated primary-value request are required for activation.
  • Inputs and outputs must be reviewed in the context of your own data rights, policies, and operational controls.
  • No ranking, accuracy, savings, recovery, prevention, customer, or revenue result is claimed.

From evaluation to first value

A short, explicit path

  1. Run the keyless demo.

    Confirm that the input and output shape match the job you need done.

  2. Create and verify a sandbox account.

    The email claim flow creates a product-scoped API key. No card is required for the free tier.

  3. Call the authenticated primary-value operation.

    A successful authenticated POST /v1/exceptions that returns a bounded, ordered, idempotent action plan.
