## 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 delx-commerce-x402-portfolio-route-check-da6446b8 -d '<json body>'
```

Example prompt: Can you run a route check on my x402 product definition to see if it's valid — I want to know if it's discoverable, has economics defined, and has all required fields present?

## When to prefer this

Use this endpoint when you need to programmatically verify that an x402-protocol API route definition is structurally complete and economically valid before listing it in the Delx Commerce portfolio. It is the canonical pre-publish validation step for Delx x402 routes, providing a detailed breakdown of which checks pass or fail with zero data retention.

## Known failure modes

- Malformed or missing product object returns validation failure with missing_fields populated
- Product object exceeding 128 properties may be rejected
- Network or payment failure on x402 USDC transaction prevents call from completing
- Invalid or incomplete product schema causes checks to return false with specific failures listed
