# VSELF API for collections

#### Getting started

VSELF API provides all the functionality of the NFT collection toolkit for NEAR-compatible version. It consists of RESTful view requests, which retrieve information from the NEAR contract, and call requests, which can make some changes or mint tokens. 

Most call requests are used for collection management. These requests are almost always available for the collection owner only. *<mark style="background-color:purple;">The only call request available for everyone is the claim reward request.</mark>* All other call requests will fail in case of a non-owner call. The view requests are available to call for everyone. The view requests are free, the call requests are paid. Learn more about payment management [here](/vself-project-documentation/nft-collection-toolkit/payment.md). &#x20;

API requests are done over HTTPS. The input and output formats for most API requests are JSON. The API is hosted [here](https://vself-prod.web.app/api/). All the requests require the developer API key as one of the parameters, which is managed using [Pagoda Console](https://console.pagoda.co/apis?tab=enhancedApi#/paths/NFT-contract_account_id---token_id/get). The requests with invalid API key will fail. There is a limitation for non-view requests the same user is able to make per minute.

In the next step, we will implement VSELF DID as a developer API key and sign all requests using the JWS scheme.
