imgauth — API di attestazione opere digitali

Digital-work attestation and proof-of-existence service operated by Spazio Genesi ETS, an Italian non-profit (third-sector entity). The client computes a SHA-256 fingerprint locally and sends only the 64-hex hash — file bytes never leave the device. The service binds that fingerprint to a signed server-side timestamp (HMAC), issues a PAdES B-LT signed PDF certificate carrying an RFC 3161 timestamp from an Adobe AATL-recognised TSA, and anchors the fingerprint in Bitcoin through OpenTimestamps across four independent calendars. Verification is free and unlimited for anyone, and the proof of existence never expires. Exposes an 18-operation public REST API (OpenAPI 3.0.3, served at the API host root), a hosted zero-install remote MCP server whose eight tools answer tools/list anonymously, an sg-attest CLI, a GitHub Action, embeddable SVG badges and three CORS-open public status endpoints. The API contract is in Italian by design. Positioned explicitly as a NON-QUALIFIED attestation under eIDAS 2.0.

imgauth — API di attestazione opere digitali publishes 14 APIs on the APIs.io network, including Agent API, Badge API, C API, and 11 more. Tagged areas include digital notarization, Timestamping, proof-of-existence, content authenticity, and Provenance.

imgauth — API di attestazione opere digitali’s developer surface includes authentication, documentation, API reference, getting-started guide, signup flow, pricing, support, and 30 more developer resources.
