Plans, Changes & Cancellation
What are the pricing and available data for each plan?
Please see the data specs by plan for pricing and available data. Some data is available even on the Free plan.
What subscription plans are available?
Four base plans are available: (1) Free Plan, (2) Light Plan, (3) Standard Plan, and (4) Premium Plan. Add-on plans that allow access to additional data not available in base plans are also available. To subscribe to an add-on plan, you must be on a paid plan (Light Plan or higher). Please see the plan chart for details.
A credit card is required at sign-up to use paid plans.
What is the difference between user registration and subscription plan selection?
Registering with J-Quants allows you to obtain sample data, but you must select a plan to obtain daily data.
Can't I get today's stock price with the free plan?
No. With the free plan, data is delivered with a 12-week delay.
What is the expiration of the free plan?
The free plan is available for one year only. Your free plan will be automatically cancelled after one year.
You can re-subscribe after the plan is cancelled.
Can I subscribe to the add-on plan only?
To use the add-on plan, you must be subscribed to the Light Plan or higher. The add-on plan cannot be used on its own.
How do I make payment?
All are monthly plans, and the monthly fee is deducted from your credit card.
Payment is made through Stripe Japan.
Your credit card information is handled by Stripe Japan and is not viewed by us.
How can I check my credit balance?
Credits incurred or used through subscription plan changes can be viewed on your receipts and invoices. Receipts and invoices are available in the Stripe customer portal, which you can access from the 'Billing' page of the dashboard.
I received an unexpected charge.
We will check your contract status. Please provide the following information via the inquiry form.
- Your registered email address
- Date and amount of the charge
- Your current plan
My credit card payment is not going through (authentication error).
J-Quants API uses Stripe for payment. Please check the following. If the issue persists, try a different card or contact your card issuer directly.
- Card details (number, expiry, security code) are correct
- Card has sufficient credit limit
- No online payment restrictions set by your card issuer
- Complete 3D Secure authentication (SMS, etc.) if prompted
Can I change my plan?
You can change your plan at any time. For base plan changes, there is no limit on upgrades to higher plans, but downgrades are limited to once per month.
When changing your subscription plan, the change takes effect immediately and the difference is charged on a pro-rata basis.
If you downgrade during a billing cycle, a credit balance for the remaining period will be issued for future payments.
After downgrading, my plan switched immediately and I lost the remaining period.
Plan downgrades take effect immediately upon completion. A credit balance for the remaining period will be issued for future payments. If you want to switch plans from next month, we recommend selecting 'Cancel' (which applies at billing period end) rather than 'Downgrade', then re-subscribing afterward.
How do I cancel my plan?
Select 'Cancel plan' on the Dashboard > Subscription screen. Cancellation applies at the end of the billing period, and you can continue using the current plan until then.
Can I cancel my subscription?
Both free and paid subscriptions can be cancelled at any time.
Plans are cancelled at the end of the billing period and will remain available from the date you indicate cancellation until the end of the billing period. Note that prorated refunds are not provided.
I cancelled my plan but would like to undo the cancellation and continue.
After submitting a plan cancellation request, you can cancel the cancellation before the effective date. Select the 'Undo cancellation' button on the 'Subscription' page of the dashboard to reverse the cancellation. After undoing, the plan will renew on the regular billing cycle.
Can I keep using the add-on plan after cancelling the base plan?
The add-on plan requires an active paid base plan.
If the paid base plan cancellation takes effect, or if you switch from the paid base plan to the Free plan, the add-on plan will be automatically cancelled on its next renewal date.
You can continue using the add-on plan until its cancellation takes effect.
What is the difference between withdrawal and subscription plan cancellation?
Cancelling your subscription plan stops plan access, but your user information remains in J-Quants API and you can still log in.
Withdrawal deletes your user information from all J-Quants API services, and you will no longer be able to log in.
How do I withdraw from the service?
Follow these steps to withdraw. Note that withdrawal permanently deletes all personal information and you will lose access to all records including invoices. 'Cancellation' only stops the plan while retaining user data; 'Withdrawal' deletes everything.
- Log in to the J-Quants API site
- Open the 'Profile' screen on the dashboard
- Click 'Proceed with withdrawal' at the bottom of the screen
Can I withdraw from the service at any time?
You may withdraw at any time. Upon withdrawal, your personal information in J-Quants API will be deleted. Please note that you will lose access to all information including paid invoices after withdrawal. You can withdraw by clicking 'Proceed with withdrawal' at the bottom of the 'Profile' screen after logging in.
If your subscription is cancelled immediately due to withdrawal, we cannot provide a prorated refund. Please also note that any credit balance you hold will be lost.
