Digital signatures and time stamps through Openapi - eIDAS-compliant electronic signatures (SES with OTP, qualified QES, e-seals, massive automatic signing) and qualified time stamping of documents. Use when the user needs a document signed electronically or time-stamped with legal validity.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Openapi eSignature & time stamping
Bearer token required (see the `openapi-auth` skill). Signing and stamping are paid, legally binding actions — confirm with the user before submitting documents.
## eSignature — `https://esignature.openapi.com`
eIDAS-compliant signatures with European legal validity.
### Signature types
- `POST /EU-SES` — Simple Electronic Signature for one or more signers, secured via OTP
- `POST /EU-QES_otp` — Qualified Electronic Signature with remote OTP certificate
- `POST /EU-QES_automatic` — massive automatic QES (high volume)
- `POST /EU-QES_eseal` — qualified electronic seal (legal-entity seal)
- `POST /verify` — verify an existing signature

How to install
mdr add openapi/openapi-skills/openapi-esignature@sha256:5e4a6fa6716102b5The line at the top of this page pins the label git:20260610.0dfad19, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
