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 with 'ok' (boolean), 'allowed' (boolean), 'host' (string), 'path' (string), 'scheme' (string), 'matched_pattern' (string if matched), and 'schema' identifier. Tells the caller definitively whether the URL is allowed and which pattern it matched.
Example use cases
Agent outbound request gating
“Before making any external API call, check if the target URL matches my approved domain list — only proceed if it's allowed. The URL is https://api.stripe.com/v1/charges and my allowlist is ['api.stripe.com', 'api.sendgrid.com'].”
Security policy enforcement for tool calls
“I want to enforce that my AI agent only calls URLs on my whitelist. Can you verify that https://hooks.slack.com/services/T00/B00/xyz is permitted against my allowlist patterns ['hooks.slack.com', '*.github.com']?”
Dynamic URL filtering in a workflow
“I'm building an automation that scrapes multiple URLs — before each one, check if it's on the approved list ['news.ycombinator.com', 'arxiv.org']. Start with https://news.ycombinator.com/item?id=12345.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/url-allowlist-match?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a fast, verifiable, pay-per-use check of whether a URL is permitted by a policy allowlist before making outbound calls. Prefer it over client-side regex matching when you need an auditable, neutral third-party validation with a cryptographic payment trail via x402/USDC, especially in multi-agent or zero-trust environments.
Side effects
- URL is malformed or unparseable — returns ok:false or validation error
- Allowlist is empty or not provided — no patterns to match against, returns allowed:false
- URL does not match any allowlist entry — returns allowed:false with no matched_pattern
- Network or service error — HTTP 5xx or payment-related 402 if payment not attached
