A company domain.
Technology signals with evidence.

What it answers

For each technology you ask about, the check returns detected, not detected or unknown. A detection includes the page it came from, a short snippet and the rule that matched. The answer is JSON; the schema is in /openapi.json.

Recorded examples from 26 October 2026, shown as dated observations.

Scope and limits

• Any public company domain can be checked. IP addresses, private or internal names and our own hosts are refused with an error and not charged. A site that blocks us, needs a login, is not HTML or does not answer within 8 seconds is not charged either.
• Only the public homepage and its response headers are inspected. Website scripts are not run, so "not detected" means no evidence was found, not that the tool is absent.
• Results may come from a cache up to one hour old; each answer carries its own observation time. A new paid request is charged even when the result is cached.
• Limits: 100 completed checks a day in total and 20 per payer.

Price and payment

0.02 USDC (20000 in USDC's 6-decimal units) on Base mainnet (eip155:8453), paid through x402 with an EIP-3009 authorization. Payment is settled only after a complete check; a failed, incomplete or refused check settles nothing. Retrying with the same signed proof returns the saved result for 7 days without a second charge.

Call it

1. Ask without paying. The answer is a 402 with the payment terms.

curl -i -X POST https://aurelmark.live/v1/website/qualify   -H "Content-Type: application/json"   -d '{"domain":"trees.com","checks":["shopify","klaviyo"]}'
# HTTP/2 402, with a PAYMENT-REQUIRED header (x402 v2, base64 JSON)

2. Download the restart-safe client (Node 22+). The Node client can request a free quote without installing packages or loading a wallet. Save it in a private directory:

mkdir -m 700 aurelmark-buyer
cd aurelmark-buyer
curl -fsS -o client.mjs https://aurelmark.live/website-qualification/client.mjs
node client.mjs quote trees.com --checks shopify,klaviyo

3. Choose to pay, with a ceiling. Download the exact-version package manifest and install the wallet SDKs only when you intend to pay. The client uses the pinned SDK's appendPaymentIdentifierToExtensions to add the required payment identifier.

curl -fsS -o package.json https://aurelmark.live/website-qualification/client-package.json
npm install --ignore-scripts --no-fund
mkdir -m 700 operations
# Bash: enter your own key privately; it is never sent to Aurelmark.
read -rs -p "Buyer private key: " BUYER_PRIVATE_KEY
export BUYER_PRIVATE_KEY
node client.mjs pay trees.com --state ./operations/trees-1.json --max-usdc 0.02 --checks shopify,klaviyo
unset BUYER_PRIVATE_KEY

4. Resume the same operation after a lost reply. No key or SDK installation is needed to resume. The client sends the identical saved body and PAYMENT-SIGNATURE, without signing again:

node client.mjs resume --state ./operations/trees-1.json

State files are private: they contain a reusable payment proof. Keep them on your own machine; do not upload, share or commit them. Each payment requires a fresh state path. The client saves and syncs the proof before sending it, and refuses an existing or unsafe file. After a timeout or pending response, keep the file and use resume; do not create a replacement payment. A partial reserved file after a disk error needs inspection before any new payment. The scope and limits above still apply.

The client verifies the fixed endpoint, recipient, Base network, native USDC and 20000-unit price before signing. The ceiling is your explicit maximum, not a recurring allowance. Downloaded packages use exact direct SDK versions. The CLI prints dated evidence, sources, reasons, limitations and billing as assessment JSON.
