# API v2 (for exchanges)
|
|
Works with update version 0.991
|
|
|
|
The API is designed to make it easier to write third-party applications. Server-side cryptography and POW operations are performed. Therefore, it is not recommended for public access, because it is not protected from DDOS attacks. Use it if applications such as the exchange server are on the same private network.
|
|
|
|
This API is available if server is running http and hosting included constant USE_HARD_API_V2.
|
|
|
|
### Set the constants (file const.lst):
|
|
* "HTTP_HOSTING_PORT":80,
|
|
* "USE_HARD_API_V2":1,
|
|
|
|
|
|
Although the API is designed for use in POST requests, it can be used for GET requests in a limited mode.
|
|
|
|
|
|
Warning: the Tera blockchain has a high rate of block confirmation (starting from 4 seconds), but since it uses PoW, it is possible to get into local orphan chains. Therefore, for a reliable transfer of value, we recommend that exchanges wait for additional time, such as 100 seconds, to interpret the finality of the transaction.
|
|
|
|
|
|
Call format:
|
|
```js
|
|
{{Server}}/api/v2/{{MethodName}}
|
|
```
|
|
Example:
|
|
```js
|
|
http://127.0.0.1/api/v2/GenerateKeys
|
|
```
|
|
|
|
As a result, JSON is returned, which contains the required result field with the value:
|
|
* 0 - the request contains errors or the result is not possible to get (for example, there is no such account),
|
|
* 1 or >1 - successful execution of the query
|
|
|
|
text - the optional field contains a detailed description of the result
|
|
|
|
All methods support the Meta parameter, if it is specified, the same value is added to the query result. This is useful for organizing your own query routing, often used in micro-service architectures.
