Output
Returns contract-specific validation checks, normalized evidence supporting each check, specific mismatch reasons where applicable, and an explicit binary acceptance or rejection status for the x402 portfolio route entry.
Example use cases
Pre-payment x402 route validation
“I'm about to pay for an x402 delivery — can you run a portfolio route check on this product object and tell me if there are any ownership or economics mismatches before I send funds?”
Agent delivery acceptance gating
“An agent just returned a result with challenge and product metadata — run the x402 portfolio route check on it and tell me whether I should accept or reject the delivery based on ownership, resource, and discoverability criteria.”
Debugging a rejected x402 portfolio entry
“My x402 portfolio entry keeps getting rejected — can you run a route check on this product data and give me the specific mismatch reasons and normalized evidence so I can figure out what's wrong?”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/x402-portfolio-route-check?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
