 24 | # Chainstack Covalent API JavaScript SDK
 25 | 
 26 |  A JavaScript SDK designed to streamline the process of developing using the integration of Chainstack with Covalent APIs, enhancing the ease of use and efficiency.
 27 | 
 28 | ## Quickstart
 29 | 
 30 | * Install the [Chainstack-Covalent integration](https://docs.chainstack.com/docs/work-with-chainstack-marketplace#install-an-app) from your Chainstack console. 
 31 | 
 32 | * Get a [Chainstack API key](https://docs.chainstack.com/reference/platform-api-getting-started#create-api-key).
 33 | 
 34 | * In your project's directory, install the Chainstack SDK:
 35 | 
 36 | ```sh
 37 | npm i chainstack-covalent-sdk
 38 | ```
 39 | 
 40 | * In a new file, import the Chainstack SDK and use your Chainstack API key in the constructor:
 41 | 
 42 | ```js
 43 | const {ChainstackApi} = require("chainstack-covalent-sdk")
 44 | 
 45 | const CHAINSTACK_API_KEY = 'YOUR_CHAINSTACK_API_KEY'
 46 | const chainstack = new ChainstackApi(CHAINSTACK_API_KEY);
 47 | ```
 48 | 
 49 | * (Optional but recommended) — The Chainstack-Covalent SDK comes with the `dotenv` package included, so you can use a `.env` file to import the Chainstack API key:
 50 | 
 51 |     - Create a `.env` file with your Chainstack API key:
 52 | 
 53 |     ```env
 54 |     CHAINSTACK_API_KEY="YOUR_CHAINSTACK_API_KEY"
 55 |     ```
 56 | 
 57 |     - Import it in your project:
 58 | 
 59 |     ```js
 60 |     const {ChainstackApi} = require("chainstack-covalent-sdk")
 61 | 
 62 |     const CHAINSTACK_API_KEY = process.env.CHAINSTACK_API_KEY
 63 |     const chainstack = new ChainstackApi(CHAINSTACK_API_KEY);
 64 |     ```
 65 | 
 66 | ## Usage
 67 | 
 68 | The Chainstack-Covalent SDK has many endpoints to get all sorts of data, from smart contract deployments to NFT data. Each endpoint takes an object as a parameter to configure the call to the Covalent API. 
 69 | 
 70 | ### Fetch token balances
 71 | 
 72 | This endpoint fetches all the token balances from the specified address on the selected chain:
 73 | 
 74 | ```js
 75 | const {ChainstackApi} = require("chainstack-covalent-sdk")
 76 | 
 77 | const CHAINSTACK_API_KEY = process.env.CHAINSTACK_API_KEY
 78 | const chainstack = new ChainstackApi(CHAINSTACK_API_KEY);
 79 | 
 80 | // Config parameters
 81 | const parameters = {
 82 |     chainName: 'eth-mainnet',
 83 |     walletAddress: '0xae2Fc483527B8EF99EB5D9B44875F005ba1FaE13',
 84 |     currency: 'USD',
 85 |     nft: true,
 86 |     noNftFetch: false,
 87 |     noSpam: true,
 88 |   };
 89 |   
 90 |   
 91 |   chainstack.fetchTokenBalances(parameters)
 92 |     .then(data => console.log(data))
 93 |     .catch(error => console.error(error));
 94 | ```
 95 | 
 96 | #### Explain the parameter object
 97 | 
 98 | The parameters object allows for fine tuning of your request, here is the explanation about the configuration parameters for `fetchTokenBalances`:
 99 | 
100 | 1. **chainName** (string, required): This parameter represents the name of the blockchain network you're interested in. For example, 'eth-mainnet' for the Ethereum mainnet. Find a complete list on the [Covalent docs](https://www.covalenthq.com/docs/networks/).
101 | 
102 |     ```javascript
103 |     const chainName = 'eth-mainnet';
104 |     ```
105 | 
106 | 2. **walletAddress** (string, required): This is the address of the wallet for which you want to fetch token balances. If you pass in an Ethereum Name Service (ENS) address or a RSK Name Service (RNS) address, it will be automatically resolved to the corresponding wallet address.
107 | 
108 |     ```javascript
109 |     const walletAddress = '0xae2Fc483527B8EF99EB5D9B44875F005ba1FaE13';
110 |     ```
111 | 
112 | 3. **quote-currency** (string, optional): This is the currency in which you want the balances to be quoted, such as 'USD' for United States Dollars. If not provided, the balances may be returned in the native currency of the blockchain network.
113 | 
114 |     ```javascript
115 |     const quoteCurrency = 'USD';
116 |     ```
117 | 
118 | 4. **nft** (boolean, optional): If set to `true`, Non-Fungible Tokens (NFTs) will be included in the response along with fungible tokens. If `false` or not provided, NFTs will not be included.
119 | 
120 |     ```javascript
121 |     const nft = true;
122 |     ```
123 | 
124 | 5. **no-nft-fetch** (boolean, optional): If set to `true`, the response will only include NFTs that have been cached. This can make the response faster, as it avoids having to fetch data about NFTs from the blockchain. If `false` or not provided, all NFTs will be included, regardless of whether they are cached.
125 | 
126 |     ```javascript
127 |     const noNftFetch = false;
128 |     ```
129 | 
130 | 6. **no-spam** (boolean, optional): If set to `true`, any tokens that are suspected to be spam will be excluded from the response. This currently supports 'eth-mainnet' and 'matic-mainnet'. If `false` or not provided, all tokens, including potential spam, will be included.
131 | 
132 |     ```javascript
133 |     const noSpam = true;
134 |     ```
135 |     
136 | Remember, this function returns a promise. Handle this promise appropriately in your code, either by using `.then()` and `.catch()` methods, or by using the `await` keyword inside an async function with a try-catch block.
137 | 
138 | ## Work in progress
139 | 
140 | This tool and its documentation is work in progress, we will be adding a complete list of endpoints available soon.

 81 |       with the Work to which such Contribution(s) was submitted. If You
 82 |       institute patent litigation against any entity (including a
 83 |       cross-claim or counterclaim in a lawsuit) alleging that the Work
 84 |       or a Contribution incorporated within the Work constitutes direct
 85 |       or contributory patent infringement, then any patent licenses
 86 |       granted to You under this License for that Work shall terminate
 87 |       as of the date such litigation is filed.
 88 | 
 89 |    4. Redistribution. You may reproduce and distribute copies of the
 90 |       Work or Derivative Works thereof in any medium, with or without
 91 |       modifications, and in Source or Object form, provided that You
 92 |       meet the following conditions:
 93 | 
 94 |       (a) You must give any other recipients of the Work or
 95 |           Derivative Works a copy of this License; and
 96 | 
 97 |       (b) You must cause any modified files to carry prominent notices
 98 |           stating that You changed the files; and
 99 | 
100 |       (c) You must retain, in the Source form of any Derivative Works
101 |           that You distribute, all copyright, patent, trademark, and
102 |           attribution notices from the Source form of the Work,
103 |           excluding those notices that do not pertain to any part of
104 |           the Derivative Works; and
105 | 
106 |       (d) If the Work includes a "NOTICE" text file as part of its
107 |           distribution, then any Derivative Works that You distribute must
108 |           include a readable copy of the attribution notices contained
109 |           within such NOTICE file, excluding those notices that do not
110 |           pertain to any part of the Derivative Works, in at least one
111 |           of the following places: within a NOTICE text file distributed
112 |           as part of the Derivative Works; within the Source form or
113 |           documentation, if provided along with the Derivative Works; or,
114 |           within a display generated by the Derivative Works, if and
115 |           wherever such third-party notices normally appear. The contents
116 |           of the NOTICE file are for informational purposes only and
117 |           do not modify the License. You may add Your own attribution
118 |           notices within Derivative Works that You distribute, alongside
119 |           or as an addendum to the NOTICE text from the Work, provided
120 |           that such additional attribution notices cannot be construed
121 |           as modifying the License.
122 | 
123 |       You may add Your own copyright statement to Your modifications and
124 |       may provide additional or different license terms and conditions
125 |       for use, reproduction, or distribution of Your modifications, or
126 |       for any such Derivative Works as a whole, provided Your use,
127 |       reproduction, and distribution of the Work otherwise complies with
128 |       the conditions stated in this License.
129 | 
130 |    5. Submission of Contributions. Unless You explicitly state otherwise,
131 |       any Contribution intentionally submitted for inclusion in the Work
132 |       by You to the Licensor shall be under the terms and conditions of
133 |       this License, without any additional terms or conditions.
134 |       Notwithstanding the above, nothing herein shall supersede or modify
135 |       the terms of any separate license agreement you may have executed
136 |       with Licensor regarding such Contributions.
137 | 
138 |    6. Trademarks. This License does not grant permission to use the trade
139 |       names, trademarks, service marks, or product names of the Licensor,
140 |       except as required for reasonable and customary use in describing the
141 |       origin of the Work and reproducing the content of the NOTICE file.
142 | 
143 |    7. Disclaimer of Warranty. Unless required by applicable law or
144 |       agreed to in writing, Licensor provides the Work (and each
145 |       Contributor provides its Contributions) on an "AS IS" BASIS,
146 |       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

150 |       appropriateness of using or redistributing the Work and assume any
151 |       risks associated with Your exercise of permissions under this License.
152 | 
153 |    8. Limitation of Liability. In no event and under no legal theory,
154 |       whether in tort (including negligence), contract, or otherwise,
155 |       unless required by applicable law (such as deliberate and grossly
156 |       negligent acts) or agreed to in writing, shall any Contributor be
157 |       liable to You for damages, including any direct, indirect, special,
158 |       incidental, or consequential damages of any character arising as a
