Plans overview

SpreadAPI has three plans: Basic, Pro and Custom. This page shows what each includes in one table and where you see the plan of your account.

The plans in one table

On every plan, a single service answers at most 1,000 calls per minute. That limit is separate from the calls per month.

What each limit means

• Published services: how many services may be online at the same time. Drafts do not count. See Published services limit.
• Workbook size: how large the workbook of a service may be. See File size limits.
• Calls per month: how many calls all services of the account answer in a calendar month. See Call limits.

Which plan fits

• Basic is for one calculator that stays online: a single price calculator, a tool for your team, a first test.
• Pro is for several services, larger workbooks and more traffic.
• Custom is for needs beyond Pro: more calls, larger workbooks, a contract, or the runtime on your own infrastructure. See On-premises runtime.

Where you see your plan

1. Open the service list.
2. Click the round icon with your initial at the top right.
3. The first entry of the menu shows your plan: Basic, Pro or Custom.

Click that entry to open Upgrade Your Plan. It shows the three plans and marks yours as CURRENT PLAN. See Upgrade and billing.

The calls of the current month against the calls of your plan are on the Analytics page under This Month. See Account analytics.

What stays when a plan changes

What your account already has is never taken away. A published service stays online and can be published again, and a workbook above the size limit can still be saved as long as it does not grow. Only new actions are measured against the limits of the current plan.

For developers and agents

• A call beyond the month's calls answers HTTP 429 with "error": "Monthly call limit reached".
• A call beyond the per-minute limit answers HTTP 429 with a Retry-After header.
• An agent connected to the account reads the limits of the plan from the action what_can_you_do, under account: plan, max_workbook_bytes, max_published_services and calls_per_month. A value of null means no limit.
• In that answer plan is the plan's name: Basic, Pro or Custom.

FAQ

What plans does SpreadAPI have?

Three: Basic (free), Pro (€99 per month) and Custom (on request). They differ in the number of published services, the workbook size and the calls per month.

What does the free plan include?

Basic includes one published service that stays online, unlimited drafts, workbooks up to 250 KB and 1,000 calls a month. The API, the AI integration, the apps and the automation connectors are included.

What does Pro include?

Pro costs €99 per month and includes unlimited published services, 10 MB for all workbooks of the account together, 10,000 calls a month and priority support.

How do I see which plan I am on?

Open the account menu at the top right of the service list. The first entry shows Basic, Pro or Custom.

Is the free plan limited in time?

No. The one published service of the Basic plan stays online permanently, and the 1,000 calls are available again every month.

Can I use AI assistants on the free plan?

Yes. The AI integration over MCP is part of every plan, including Basic.

When do I need the Custom plan?

When you need more than 10,000 calls a month, workbooks beyond the Pro size, a contract with agreed support, or the on-premises runtime. Write to support@airrange.io or click Custom in Upgrade Your Plan.

Is there a limit on how many services I can create?

No. Drafts are unlimited on every plan; only the number of services published at the same time is limited on Basic.

As an agent, how do I find out the limits of my user's account?

Call what_can_you_do on the account connection and read account: it returns the plan's name (Basic, Pro or Custom), the largest workbook in bytes, the number of published services and the calls per month. null means the plan sets no limit.
