Projects
Each project contains one or more endpoints.
When your account reaches the maximum number of projects, Forge API prevents new projects from being created until you delete an existing project or upgrade your plan.
Endpoints
Endpoints belong to projects.
The Free plan supports up to ten endpoints in a project. Paid plans remove this limit.
Organise related endpoints
Monthly requests
Every public API request counts towards your monthly allowance.
Requests are counted regardless of whether they originate from a web browser, mobile application, Postman, automated tests or another HTTP client.
What happens when I reach my limit?
Response size
Each endpoint has a maximum JSON response size.
Larger JSON responses require higher plans. This encourages realistic responses while protecting overall platform performance.
Account storage
Storage includes all endpoint configurations and JSON stored in your account.
If you approach your storage allowance, consider removing unused projects or upgrading to a larger plan.
Protected endpoints
Required request headers are available on paid plans.
Configure one or more secret request headers to restrict who can call your mock endpoints.
Learn about protected endpoints âResponse delays
Simulate slower APIs.
Paid plans allow configurable response delays so you can test loading indicators, skeleton screens and timeout behaviour.
Frequently asked questions
Will upgrading delete my projects?
No. Upgrading increases your available limits without removing existing projects or endpoints.
Do requests reset every month?
Yes. Monthly request allowances automatically reset at the start of a new billing period.
Can I downgrade later?
Yes. If your usage exceeds the limits of the lower plan, you may need to reduce usage before creating additional resources.
Can I increase only one limit?
Limits are determined by your subscription plan rather than being purchased individually.
Need more capacity?
Upgrade your Forge API plan whenever your projects outgrow the current limits.
