Tamper-evident receipts for every AI call.

Regulations now require auditable logs for AI decisions in lending, hiring, healthcare, and other high-risk domains. Attestiq sits between your application and your AI provider, logging every call and writing a cryptographic receipt to a decentralized ledger — proving when each call happened and that the record was never edited.

Built for the new AI compliance regime.

The EU AI Act, the Colorado AI Act, NYC Local Law 144, and similar regulations now require companies using AI to make consequential decisions to maintain auditable records of every model invocation. Internal audit teams, external regulators, and litigation discovery all expect the same thing: proof that a specific AI call happened on a specific date, with a specific input and a specific output, and that the record has not been altered.

Traditional application logs do not meet this bar. They sit in databases that engineers can edit. They sit on disks that administrators can rotate. There is no cryptographic guarantee that the audit trail you produce today reflects what actually happened six months ago.

Attestiq closes that gap. Every AI call routed through us is hashed and committed to an append-only chain on the Internet Computer — a public, decentralized network whose state is signed by a global set of nodes. The result is an audit trail that you do not control and cannot quietly modify. That is precisely the property auditors and regulators are looking for.

For teams subject to AI audit requirements.

Attestiq is purpose-built for organizations whose AI-assisted decisions face external scrutiny.

Three steps. No infrastructure changes.

1
Point your application at Attestiq.

Change your AI provider's base URL to your Attestiq endpoint. Attestiq speaks the OpenAI-compatible API shape, so most integrations are a one-line change. Bring your own provider key — Attestiq never stores it.

2
We hash and forward.

Every call passes through our proxy. We compute SHA-256 hashes of the request and response in memory, forward the call to your AI provider unchanged, and return the response to your application — adding a receipt ID in the response header.

3
Receipts are written to a public ledger.

The hashes plus metadata (model, timestamp, token count, your internal correlation ID if you supply one) are committed to an append-only chain on the Internet Computer. The chain is cryptographically linked end-to-end: any attempt to edit a past entry breaks every entry after it. When you need evidence later, you export a verifiable evidence package from your dashboard.

We never see your prompts or your customers' data.

Attestiq stores hashes and metadata only. The actual prompts and responses stay in your systems, where they already need to live for product reasons. We never store the content of an AI call, and we cannot reconstruct it from what we hold. This is structural — not a policy promise that could be reversed.

You keep
The original prompts and responses.
We hold
Cryptographic fingerprints, model name, timestamp, token count, customer ID.
Anyone can verify
That a specific receipt is authentic and unaltered, by re-hashing the original content and comparing.

This design eliminates the entire category of "Attestiq leaked our prompts" risk and makes Attestiq compatible with GDPR, HIPAA, and most internal data-residency policies out of the box.
