How this service works
Launch directories from 11 popular public lists that were dead, unreachable, erroring or redirecting to another site on our Oct 2026 live check (DNS re-checked over DoH). Drop them from a launch plan. Optional filter by status kind.
Output
A JSON object containing a count and array of directory entries, each with the domain name, a human-readable status string (e.g. 'dead: domain does not resolve'), the UTC date the check was performed, and how many public lists that directory appears in.
Example use cases
Pre-launch directory list cleanup
“Before I start submitting my new SaaS to directories, pull all the dead ones from SubmitCheck's October 2026 check so I can remove them from my list and not waste time.”
Identify moved or unreachable directories
“Can you get me all the directories marked as moved or unreachable from the SubmitCheck data? I want to see if any popular ones have just changed their URL.”
Audit curated directory lists for validity
“I'm compiling a fresh launch checklist — use SubmitCheck to filter out any directories with status 'any' (all problematic ones) so I only keep the live, working ones.”
Technical details
Endpoint
GEThttps://submitcheck.appin60.com/api/v1/dead-directories?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a pre-verified, dated snapshot of which startup/SaaS/AI-tool directories are dead, moved, or unreachable — specifically sourced from 516 directories aggregated across 11 public lists and checked in October 2026. Prefer this over manual checking or general web search when you want structured, filterable results with status labels and list-frequency signals, without having to probe each directory yourself.
Side effects
- Invalid 'kind' enum value returns a validation error
- No results returned if no directories match the requested status filter
- Service may return stale data if the October 2026 check has not been refreshed
- Network timeout if the upstream API is unavailable
- Payment of 0.005 USDC required per call; missing payment returns 402
