🔗 URL shortener

Short links whose code is derived from the URL and anchored on-chain — so the mapping is verifiable and censorship-resistant, not a row in a database someone can edit or delete.

Endpoints

curl -X POST https://bsv.cx/s -H 'content-type: application/json' -d '{"url":"https://example.com"}'

Verify it yourself

Recompute the code from the target URL, then read the OP_RETURN in the anchor transaction — it carries bsv.cx / url1 / <code> / <url>. No trust in bsv.cx required.

And you don't have to trust an explorer for this, either. bsv.cx runs its own block-headers service, syncing the chain's headers directly over the BSV peer-to-peer network. For every anchor it recomputes the transaction's block Merkle root from an SPV proof and confirms it against those headers before publishing the proof on the record. Look for the green "✓ Independently verified against bsv.cx's own block headers" line on any proof page, open it, and recheck the same proof against any header source you trust — no explorer, and no bsv.cx, in the trust path.
