How this service works
Check up to 20 launch-directory domains at once: our Oct 2026 record (live/dead/moved, free option, account, submit URL) for known ones, and a live HTTP check right now for unknown ones. Pass domains comma-separated.
Output
A JSON object with a count of results and an array of per-domain entries, each containing whether the domain is known in the dataset, its current status (live, dead, moved/redirected with target), and a checked timestamp. Known domains reflect data from the October 2026 re-check; unknown domains are checked live at call time.
Example use cases
Pre-launch directory vetting for a SaaS
“I'm about to launch my SaaS product and I've got a list of 10 directories I want to submit to. Can you check betapage.co, saashub.com, and startupstash.com to see if they're still live, and whether any of them require a backlink or a paid plan for a basic listing?”
Cleaning up a stale directory submission list
“I have an old list of startup directories that might be outdated — can you check the status of alternativeto.net, f6s.com, and erlibird.com to see which ones have died, moved, or changed their free listing requirements since last year?”
Filtering AI tool directories before an automated submit run
“Before my agent starts submitting my AI tool to directories, can you check theresanaiforthat.com, futurepedia.io, and aitoolsdirectory.com to confirm they're all still live and not requiring a backlink or months-long queue for a free listing?”
Technical details
Endpoint
GEThttps://submitcheck.appin60.com/api/v1/check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to validate the current status of known startup, SaaS, or AI-tool submission directories before launching a campaign — especially when working from curated community lists that may be partially stale. It is more reliable than a generic HTTP ping because it includes structured metadata about free-listing conditions (backlink requirements, account gates, queue lengths) drawn from a curated October 2026 re-check of 516 directories across 11 public lists. Prefer alternatives if you need to check arbitrary websites unrelated to product launch directories.
Side effects
- Domain not in the 516-directory dataset returns known:false with a live check
- More than 20 domains in a single call may be rejected or truncated
- Invalid domain format in the comma-separated list may cause a parse error
- Payment failure (x402) if USDC funds are insufficient
- Timeout if a live check of an unknown domain takes too long
- Redirected domains may show old destination if not re-checked recently
