Payment & Invoices

Can I register without a credit card?

Only credit card payments are accepted.

My plan was cancelled because my credit card payment failed.

If payment fails, your plan will be automatically cancelled. Please re-register for the plan.

I received a payment confirmation email from my credit card company.

To prevent unauthorized use, your credit card company may send a confirmation email about card usage. Please sign in to J-Quants API and verify your credit card from the portal.

Can you issue a qualified invoice (Japanese consumption tax invoice)?

Please contact us via the inquiry form for qualified invoice issuance. We will respond after reviewing your request.

Where can I view or download receipts?

A receipt link is included in the Stripe payment confirmation email. You can also download receipts from the billing history on the Dashboard > Billing screen.

The credit card registration screen (authentication screen) won't open.

The credit card authentication screen is displayed as a popup and may be blocked by your browser's popup blocker. Please try the following:

• Allow popups for this site (jpx-jquants.com) in your browser settings
• Try a different browser (Chrome, Safari, Firefox, etc.)
• Try a different device (PC or smartphone)
• If the issue persists, try a different credit card

Can you explain the billing cycle?

The monthly usage fee is billed in one-month cycles starting from the date you registered for a paid plan. The first payment is made at the time of plan registration, and the next payment is due on the same date of the following month (if that date does not exist in the following month, the last day of that month applies).

For example, if you subscribe on April 25th, the service period does not end on April 30th, but continues until May 25th — the same date in the following month. The next payment is also made on May 25th, and billing continues on the 25th of each month thereafter.
