eSignVerification

Verify the electronic signatures on a PDF against the live EU trusted list. Establishes whether each signature is qualified (QESig) or advanced (AdESig) under eIDAS, checks byte-range integrity and CMS/PKCS#7 cryptography, and anchors the signer's issuing CA in the published trusted list of every EU member state.

Skills

• esign_verify
  [Execution] Verify the electronic signatures on a PDF. Send the document as base64 in `pdf_base64`. Returns one entry per signature: the signer, the issuing CA, the claimed signing time, the eIDAS qualification (QESig / AdESig / Unknown), and the individual checks — byte-range integrity, CMS/PKCS#7 cryptographic validity, EU trusted-list anchoring, and whether the signature covers the whole document. Partial coverage is reported as a fact, not as tampering. Consumes 1 verification credit.
• esign_status
  [Research] Remaining verification credits and the expiry date of the soonest-expiring batch. Free — no credits consumed.
• esign_trusted_list
  [Research] State of the EU trusted list this service verifies against: number of anchors, number of member-state lists, and when it was last published. Call this to judge how current the trust data is before relying on a verdict. Free — no credits consumed.
