Example prompt: Before I pay for this x402 agent delivery, run a portfolio route check on this product entry to verify ownership, economics, and discoverability — and tell me whether I should accept or reject it.

## When to prefer this

Use this endpoint when you need a lightweight, in-memory, no-external-provider validation of a single x402 portfolio entry before paying or accepting an agent delivery. It is purpose-built for the x402 payment protocol and returns structured acceptance/rejection decisions with evidence — prefer it over generic validation tools when working with x402 challenge/result metadata.

## Known failure modes

- Malformed or missing product object returns a validation error
- Product object exceeds 128 properties limit causing rejection
- Ambiguous or incomplete metadata results in inconclusive checks
- Network timeout returns no result
- Unexpected schema in product fields may yield partial or failed checks
