# SignSealShip documentation

> Sign, notarize, and ship documents with verifiable cryptographic evidence. Build Verified Closing Rooms and seal Closing Passports over the partner API.

SignSealShip is a pay-per-use platform for getting documents signed, notarized (including remote online notarization), and shipped — with cryptographic evidence you can verify without trusting us. Every sealed document carries a Google Cloud KMS signature, independent timestamp evidence, and a public verification URL.

For title, escrow, legal, and lending firms, the partner API adds **Verified Closing Rooms**: one shareable page per transaction that bundles a deal's documents, signer progress, evidence badges, and shipping status behind a single link — plus a sealed, versioned **Closing Passport** that rolls the whole room's evidence into one verifiable artifact.

## What the platform does

<Columns cols={2}>
  <Card title="Sign" icon="pen-line">
    First-party e-signature with signed audit trails. Signers work from a link — no accounts required.
  </Card>

  <Card title="Seal" icon="stamp">
    Executed documents are sealed with an asymmetric Google Cloud KMS signature and byte-range tamper evidence, then timestamped by independent authorities.
  </Card>

  <Card title="Ship" icon="package">
    Physical originals move by tracked carrier, and tracking status appears on the order and in its Closing Room.
  </Card>

  <Card title="Prove" icon="badge-check">
    Every seal gets a public verification URL. Anyone — a counterparty, an auditor, a court — can check it without a SignSealShip account.

## Honest boundaries

The evidence in these docs is cryptographic fact, not legal advice. SignSealShip never claims evidence it does not hold: statuses shown in a room are our live records, sealed hashes are independently verifiable artifacts, and every Closing Passport states exactly what it does and does not cover.
