# Post-Purchase Event Continuity Checker

> Post-Purchase Event Continuity Checker is a paid API for AI agents from api.blockchainmoneymap.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Validates and checks continuity/consistency across post-purchase order lifecycle events (order, shipment, delivery, refund, return, webhook) against a reference snapshot.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability post-purchase-event-continuity-checker-639a6396 -d '<json body>'
```

Example prompt: Check the continuity of this order's post-purchase events — order ID 'ORD-98234', current status 'delivered', with shipment and delivery events present, tracking present, no refunds, and compare against the reference snapshot I have from 2 hours ago to flag any inconsistencies.

## When to prefer this

Choose this endpoint when you need to programmatically verify the integrity and continuity of post-purchase order lifecycle events — especially when comparing a current order state against a known-good reference snapshot to detect anomalies, fraud, missing transitions, or inconsistent webhook/refund/shipment states. Prefer this over general-purpose validation when you have structured e-commerce order event arrays and want a dedicated continuity/consistency check.

## Known failure modes

- Missing required fields (order_id_label, order_status, order_events) returns validation error
- reference_facts object missing or malformed causes comparison failure
- Event arrays exceeding maxItems:50 are rejected
- Invalid mode value (not 'check') results in error
- Payment failure via x402 protocol returns 402 response
- Malformed JSON body returns 400 error
