Preparations

API Key

Getting an API key is required. An API key is an unique key for each API user. It is used for this service to identify API users. Any API users who wish to use the APIs on this service must request TSE to issue API keys in advance. The API key should be set in the X-API-KEY in header every time you send an API call.

IP Address Whitelisting

You must submit the global IP address of the system making API calls to TSE. All API keys are linked to global IP addresses, and API calls from IP addresses not submitted in advance will not be accepted.

Rate Limits

The maximum frequency of API calls is limited to approximately once every second per API key. This value is subject to change in the future. When the limit is reached, the user will receive an error response. Overly frequent access is prohibited as stated in the Terms and Conditions. If such behavior is detected, TSE may issue a warning to the user.
