Web Evidence Receipt

Capture a webpage as point-in-time proof with an Axiom-Receipt: preserved evidence, trusted time, and independent verification.

The web changes constantly. Pages are edited, posts disappear, and screenshots can be altered. Web Evidence Receipt gives you a way to preserve what you saw at a specific point in time. With one capture, the extension creates an Axiom-Receipt containing preserved webpage evidence, independent time anchors, post-quantum signatures, and the verification materials needed to evaluate the receipt later. When you capture a page, Axiom-Infra simultaneously captures a verifiable snapshot of the world at that moment, then weaves it all together under four layers of post-quantum signatures. Capture the web Preserve webpage evidence from the tab you selected. Prove the time Independent time anchors are corroborated by world-state evidence collected during issuance. Verify the evidence Each receipt is cryptographically sealed and can be independently checked later. For everyday users Capture a webpage when it matters and keep the resulting evidence package for your own records. Two free captures are available each month, with additional capture options available when needed. For investigators, legal teams, and compliance professionals Web Evidence Receipt creates a tamper-evident package designed to preserve digital evidence and support later verification rather than relying on a screenshot alone. What an Axiom-Receipt includes Preserved webpage evidence. The package contains the webpage evidence and screenshot produced during the user-initiated capture. Independent time anchors. Capture-time evidence is supported by independent time sources and corroborated by world-state evidence collected during issuance. Post-quantum signatures. Current receipts use four layers of ML-DSA-87 post-quantum signatures as part of the Axiom receipt-verification profile. Trusted timestamp evidence. Receipt packages include RFC 3161 timestamp evidence from an external timestamp authority. Verification materials. The downloaded package includes the receipt, evidence, and trust material needed to evaluate its integrity later. Full Claim ID. Each receipt has a unique Claim ID that can be retained with the downloaded evidence package and used in the verification workflow. No account required. The extension does not rely on an email account or permanent server-side package archive. After the package is downloaded and deletion is confirmed, Axiom deletes its temporary recovery copy while the issuance record remains verifiable. Web Evidence Receipt is built on Axiom-Infra point-in-time proof infrastructure. For product or workflow integrations, contact info@axiominfra.io.
