Model-agnostic certifying proxy for AI agents

Prove that it
happened.

Your agents — Claude, GPT, Mistral, your internal APIs — execute thousands of calls. When a provider denies delivery or an audit demands evidence: who has proof?

ArkForge certifies every AI API call your systems make — regardless of model or provider. Each proof is independently verifiable by regulators, auditors, or counterparties without routing through ArkForge.

  • EU AI Act Article 13 — traceability requirements met out of the box
  • DORA & NIS2 — immutable audit logs with certified timestamps
  • Zero infrastructure — one API endpoint, no servers to deploy or maintain
  • SLA & priority support — dedicated channel, custom integrations
  • Dispute resolution — each proof seals both sides; counterparty cannot repudiate
EU AI Act DORA NIS2 eIDAS compatible
enterprise — immutability model
# Every proof anchored in THREE external systems
# ArkForge cannot alter or revoke after issuance

🇪🇺 EU AI Act — Aug 2026 enforcement

Your AI operations need
a verifiable paper trail.

The EU AI Act requires high-risk AI systems to maintain logs that are accurate, complete, and tamper-resistant. Agent logs are mutable. ArkForge proofs are not.

Article 13

Transparency & traceability

Every AI inference call is fingerprinted, timestamped, and anchored to a public immutability ledger. Inspectable by regulators at any time.

Article 17

Quality management system

Bilateral proofs capture both the prompt and the response. Providers cannot retroactively deny what they delivered.

DORA · NIS2

Operational resilience

Certified timestamps from WebTrust-accredited TSAs. Proofs verified against DigiCert, FreeTSA, and Sigstore — not against ArkForge. Infrastructure-independent.

Enforcement starts August 2026

High-risk AI system operators face fines up to €30M or 6% of global annual turnover. ArkForge deploys in under 10 minutes and covers every model in your stack — Claude, GPT, Mistral, open-source models — with one proxy endpoint.

How it works

One API call. Three things happen simultaneously.

Step 01

Route

Replace your target API URL with the Trust Layer proxy endpoint. Add your API key header. Nothing else changes.

Step 02

Forward

Request is relayed to the target API. Request and response are SHA-256 fingerprinted. The provider receives the original payload unchanged.

Step 03

Prove

Ed25519 signed. RFC 3161 timestamped by a WebTrust-certified TSA. Anchored in the Sigstore Rekor public ledger. Proof ID returned in the response.


3 independent witnesses

Even if ArkForge shuts down tomorrow, every proof issued today remains verifiable against public systems.

Ed25519 Signature

Origin authentication. Every proof signed with ArkForge’s Ed25519 key. Public key is published and independently verifiable by anyone.

ed25519:_31W2HE6aUro

RFC 3161 Timestamp

Certified timestamp from a pool of WebTrust-accredited authorities — FreeTSA → DigiCert → Sectigo — with automatic failover.

2026-04-08T14:32:01Z

Sigstore Rekor Ledger

Every proof appended to Sigstore’s public Rekor transparency ledger. Tamper-evident. Verification calls Sigstore — not ArkForge.
