How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object indicating whether the URL's port is allowed (boolean), the effective port number extracted from the URL, a pass/fail status string, and cryptographic evidence including the SHA-256 hash of the input and a flag confirming no data retention or external calls were made.
Example use cases
Security policy enforcement for agent webhooks
“Before my agent calls this webhook at https://partner-api.example.com:9090, verify that port 9090 is in my allowed list of 80, 443, and 8080 — I don't want it hitting non-standard ports.”
URL compliance check in CI pipeline
“I'm deploying a new service at https://staging.myapp.io:3000 — can you confirm whether port 3000 is allowed given our policy only permits 80, 443, and 3000?”
Validate third-party integration endpoint port
“We just received an integration URL from a vendor: https://data.vendor-corp.com:5432. Can you check if that port is compliant with our whitelist of 80, 443, and 8443?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/url-port-policy-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, auditable, pay-per-call check that a URL's port conforms to a whitelist policy — especially in agentic or automated workflows where no signup, no session state, and cryptographic evidence of non-retention matter. Prefer it over rolling your own port-parsing logic when you need verifiable, tamper-evident results with an immutable evidence hash. Not suitable for full URL security scanning or firewall rule management.
Side effects
- URL is malformed or missing a valid host — validation may fail or return an error
- Port extracted from URL is not in the allowed_ports array — returns allowed: false and status: fail
- allowed_ports array exceeds 256 items — rejected by schema
- URL exceeds 8192 character limit — rejected by schema
- Empty or null URL submitted — likely returns a validation error
- No allowed_ports provided — behavior may default to deny-all or error
