API plans are not billed dynamically for short usage spikes. Each plan has fixed request limits per second and per minute (RPS and RPM). If you exceed those limits, requests are blocked with a 429 response rather than incurring overage charges. To handle higher or spiky workloads, you can upgrade, customize your plan, or negotiate enterprise terms.
For uptime or incident updates, contact 1inch Support.
Standard plans apply limits broadly. But you can use the custom plan configurator and set the RPS and calls limit at the API Product level.
The API keys share the RPS and call limits across the account.
Yes, all 1inch Business paid plans include a minimum data retention of 30 days, with some tiers offering up to 90 days of retention depending on the package selected.
The upgrade takes effect immediately after you pay the invoice. Any unused calls or credits from your current billing period are automatically applied as a discount toward the new plan, and you only pay the difference.
Downgrades take effect at the start of your next billing cycle. No refunds or unused quota transfers are provided when moving to a lower plan.
The downgrade will still take effect at the end of your current billing cycle. However, if you submit it less than 4 days before renewal, the invoice for the next cycle is generated immediately.
If the renewal has already gone through, your downgrade will apply after one more billing cycle: a month or a year, depending on your subscription.
To activate your downgraded plan, you must create and pay the invoice for it. If payment isn’t completed, your account will be switched to the Dev (Free) Plan.
Sure! You can cancel your downgrade request anytime before the next billing cycle begins.
Your subscription stays active until the end of your current billing period (monthly or yearly). No refunds are issued for the remaining time—you’ll keep access until the period ends.
