Service
Fact-checking (claim verification) over HTTP for software and AI agents. You send a claim as text; we analyze it using public web search and return a JSON response with a score, references, and a short summary.

Payments & compliance
Card payments are processed by Stripe, Inc. via Checkout. Full card numbers are not stored on our servers; handling follows Stripe’s policies.
The legal notice below (Japan Act on Specified Commercial Transactions) lists the seller name, contact, payment method, delivery timing, and return policy. Sign-up is online only; we do not publish a physical address on this page and respond to lawful disclosure requests by email.
Pricing
Prices are shown in Japanese yen (JPY), tax included. Usage-based: one verification request equals one billable API call.
¥100 (tax included) per request
Included: one fact-check API use for that paid request. Your card issuer or network may charge fees under their own rules, in addition to our listed price.
Payment, cancellation & refunds
Payment
Credit and debit cards via Stripe Checkout. Follow the on-screen steps. When payment completes, API access is authorized for that purchase.
Cancellations & refunds
This is a digital service (API-delivered verification). After verification has completed and results have been delivered, we do not offer refunds or cancellations. Where Japanese law or other applicable law requires a refund, that obligation still applies.
For duplicate charges, clear payment errors, or obvious system failures, contact us at the email below; we will review and respond in good faith.
