How this service works
Startup/SaaS/AI-tool launch directories re-checked live Oct 2026, filtered by category and free option. Each row: live status, submit URL, free/badge/queue/paid, lowest price, account needed, captcha, Tranco rank. Up to 50 rows sorted by popularity.
Output
A JSON array of up to 50 directory records, each containing: directory name, domain, category, live/dead status, direct submit URL, free option type (yes/backlink/queue/paid), lowest paid price in USD, whether an account is needed, whether a captcha is present, any wait or editorial condition, and Tranco popularity rank — all verified in an October 2026 live check. Also includes the total count and the query filters applied.
Example use cases
Free AI directory shortlist for launch
“I'm launching an AI tool next week — can you get me a list of up to 30 AI directories that have a plain free listing option, sorted by popularity, from SubmitCheck?”
No-account SaaS submission pipeline
“Find me all SaaS directories on SubmitCheck where I can submit without creating an account and where a free option exists — I want to blast my product out quickly.”
Paid-only launch platform research
“Show me up to 20 launch-platform directories from SubmitCheck that are paid-only so I can budget for a premium submission campaign for my startup.”
Technical details
Endpoint
GEThttps://submitcheck.appin60.com/api/v1/directories?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a bulk, pre-verified list of launch directories filtered by category or free-tier availability, rather than looking up a single domain. It's ideal for building automated submission pipelines, prioritizing outreach by Tranco popularity, or quickly discovering which directories are still live without manually checking each one. Prefer this over the single-domain lookup sibling when you want to explore or enumerate directories rather than verify a specific one.
Side effects
- Invalid enum value for 'free', 'account' filter returns 400 validation error
- Category string not recognized returns empty results or 400
- Limit outside 1-50 range may be clamped or return error
- Payment not attached or insufficient USDC balance returns 402
- No directories match the filter combination, returning count:0 with empty results array
