Refund Policy

Last updated October 15, 2026.

Prepaid credit (card purchases)

• Unused credit, within 30 days: email chtwebllc@gmail.com within 30 days of purchase with your purchase email or the first characters of your API key, and we will refund the unused part of that purchase to your card. The key's balance is reduced by the same amount.
• Failed checks are never charged: if a check fails on our side, its cost is returned to your balance automatically.
• After 30 days, credit stays on your key and doesn't expire, but is not refundable except where required by law or if we discontinue the Service.
• Lost keys can't be recovered. If you lose a key with credit on it, contact us with your purchase details and we will review it.

Per-call payments (x402 and MPP)

A per-call payment is settled only after your check has run successfully, and if it fails on our side no payment is taken. Because settled payments are on-chain transfers, they are final. If you believe you were charged for a check that didn't return a result, email chtwebllc@gmail.com with the transaction ID and we will make it right.

Disputes

Please contact us before disputing a card charge; we answer billing questions promptly. Disputed purchases have their API key switched off while the dispute is open.
