# SubmitCheck Launch Directory Status Checker

> SubmitCheck Launch Directory Status Checker is a paid API for AI agents from submitcheck.appin60.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-23).

Looks up the live status of startup, SaaS, and AI-tool submission directories — flagging dead links, backlink requirements, long queues, and account requirements.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability submitcheck-launch-directory-status-checker-32a5bbe4
```

Example prompt: Before I start submitting my SaaS product, can you check the live status of these directories for me: betapage.co, pitchwall.co, and insidr.ai — I want to know which are still live, which have moved, and whether any require a backlink or account to list for free?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
