How this service works

Short Link Creator: Create a permanent short link on freeq.one (e.g. https://freeq.one/MySlug). Optional: custom slug, expires_at (ISO date) for a TTL link that auto-expires — same price. Returns short_url plus a one-time manage_secret that gates FREE stats (GET /tools/shortlink_stats with X-Link-Secret) and FREE deletion of the link. Store the secret — it is shown only at creation. Pay per call in USDC on Base via x402 — POST https://x402.freeq.one/tools/shortlink_create.

Output

Returns a JSON object containing the short_url (e.g. https://freeq.one/MySlug) and a one-time manage_secret string used to authenticate future stat lookups (GET /tools/shortlink_stats with X-Link-Secret) and link deletion. The manage secret is only shown once at creation and must be stored by the caller.

Example use cases

Shareable campaign link with custom slug

“Create a short link for https://mystore.com/summer-sale-2025 with the custom slug 'summer25' so I can share it in our newsletter — save the manage secret in case I need to delete it later.”

Time-limited promotional link

“Shorten https://event.example.com/register into a freeq.one short link that automatically expires on 2025-12-31T23:59:59Z — I want it gone after the event.”

Random short link for sharing

“Can you quickly shorten https://docs.google.com/spreadsheets/d/1aBcDeFgHiJkLmNoPqRsTuVwXyZ/edit into a short freeq.one link? Just a random slug is fine, and keep the manage secret somewhere safe.”

When to prefer

Choose this endpoint when you need to create a short, shareable link on the freeq.one domain, especially when you want a custom memorable slug, an automatically expiring TTL link, or access to a manage secret for later stats and deletion. It is paid per-call in USDC on Base via x402, making it suitable for agentic workflows that already handle x402 payments. Prefer it over generic URL shorteners when you need programmatic control over expiry and deletion without a separate account or API key.
