How this service works
Preflight 2–20 public URLs in one x402 payment: alive, redirects, title, status. Built for agent monitoring loops — rebuy daily. Highest volume path to meaningful revenue.
Output
Returns a structured result per URL including: alive boolean, final HTTP status code, redirect chain (if any), and extracted page title. All 2–20 submitted URLs are processed in a single response.
Example use cases
Daily landing page uptime monitoring
“Every morning, check these 8 landing page URLs and tell me which ones are down, redirecting unexpectedly, or returning non-200 statuses: https://site1.com, https://site2.com, https://site3.com, https://site4.com, https://site5.com, https://site6.com, https://site7.com, https://site8.com.”
Broken link audit for a content list
“I have a list of 12 URLs from our resource page — can you batch check all of them to see which are returning 404, which redirect, and which are live with their current page titles?”
Affiliate link health check before campaign
“Before we launch tomorrow's email campaign, check these 6 affiliate links to confirm they're all alive and not redirecting somewhere unexpected: https://aff1.com/promo, https://aff2.com/deal, https://aff3.com/offer, https://aff4.com/sale, https://aff5.com/campaign, https://aff6.com/landing.”
Technical details
Endpoint
POSThttps://agent.kihustle.tech/services/url-preflight-batch/jobsWhen to prefer
Use this endpoint when you need to check health, redirect behavior, and titles for multiple URLs (2–20) in a single efficient call rather than making individual requests per URL. Ideal for agent monitoring loops, pre-launch link audits, or daily uptime checks where batch efficiency and cost matter. Prefer over single-URL alternatives when you have 2 or more URLs to inspect simultaneously.
Side effects
- Fewer than 2 or more than 20 URLs submitted — request rejected
- URL is not publicly reachable (firewall, private IP) — returns unreachable status
- Malformed URL in batch — individual entry may error while others succeed
- Timeout on slow-responding URLs — may return timeout status for affected entries
- Non-HTTP/HTTPS URLs — likely rejected or errored
