@starton/sdk

🏗 Under construction! 🏗

This is an alpha release of the Starton SDK. We are still working on the documentation and examples and there may be breaking changes between versions without a major version update. Therefore, we recommend pinning usage to a specific package version. This way, you can install the same version each time without breaking changes unless you are intentionally looking for the latest version.

If you have any questions, please reach out to us on Discord.

SDK Installation

The SDK can be installed with either npm, pnpm, bun or yarn package managers.

NPM

Custom HTTP Client

The TypeScript SDK makes API calls using an HTTPClient that wraps the native Fetch API. This client is a thin wrapper around fetch and provides the ability to attach hooks around the request lifecycle that can be used to modify the request or handle errors and response.

The HTTPClient constructor takes an optional fetcher argument that can be used to integrate a third-party HTTP client or when writing tests to mock out the HTTP client and feed in fixtures.

The following example shows how to use the "beforeRequest" hook to to add a custom header and a timeout to requests and how to use the "requestError" hook to log errors:

1import { Starton } from "@starton/sdk";
2import { HTTPClient } from "@starton/sdk/lib/http";
3
4const httpClient = new HTTPClient({
5  // fetcher takes a function that has the same signature as native `fetch`.
6  fetcher: (request) => {
7    return fetch(request);
8  }
9});
10
11httpClient.addHook("beforeRequest", (request) => {
12  const nextRequest = new Request(request, {
13    signal: request.signal || AbortSignal.timeout(5000)
14  });
15
16  nextRequest.headers.set("x-custom-header", "custom value");
17
18  return nextRequest;
19});
20
21httpClient.addHook("requestError", (error, request) => {
22  console.group("Request Error");
23  console.log("Reason:", `${error}`);
24  console.log("Endpoint:", `${request.method} ${request.url}`);
25  console.groupEnd();
26});
27
28const sdk = new Starton({ httpClient });

Pagination

Some of the endpoints in this SDK support pagination. To use pagination, you make your SDK calls as usual, but the returned response object will also be an async iterable that can be consumed using the for await...of syntax.

Here's an example of one such pagination call:

1import { Starton } from "@starton/sdk";
2
3const starton = new Starton({
4  apiKey: "<YOUR_API_KEY_HERE>",
5});
6
7async function run() {
8  const result = await starton.wallet.getAll({
9    limit: 20,
10    page: 0,
11  });
12
13  for await (const page of result) {
14    // Handle the page
15    console.log(page);
16  }
17}
18
19run();
20

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

Name	Type	Scheme
apiKey	apiKey	API key

To authenticate with the API the apiKey parameter must be set when initializing the SDK client instance. For example:

1import { Starton } from "@starton/sdk";
2
3const starton = new Starton({
4  apiKey: "<YOUR_API_KEY_HERE>",
5});
6
7async function run() {
8  const result = await starton.data.getBalance({
9    address: "0xc2132d05d31c914a87c6611c10748aeb04b58e8f",
10    network: "polygon-mainnet",
11  });
12
13  // Handle the result
14  console.log(result);
15}
16
17run();
18

File uploads

Certain SDK methods accept files as part of a multi-part request. It is possible and typically recommended to upload files as a stream rather than reading the entire contents into memory. This avoids excessive memory consumption and potentially crashing with out-of-memory errors when working with very large files. The following example demonstrates how to attach a file stream to a request.

[!TIP]

Depending on your JavaScript runtime, there are convenient utilities that return a handle to a file without reading the entire contents into memory:

• Node.js v20+: Since v20, Node.js comes with a native openAsBlob function in node:fs.
• Bun: The native Bun.file function produces a file handle that can be used for streaming file uploads.
• Browsers: All supported browsers return an instance to a File when reading the value from an <input type="file"> element.
• Node.js v18: A file stream can be created using the fileFrom helper from fetch-blob/from.js.

1import { Starton } from "@starton/sdk";
2
3const starton = new Starton({
4  apiKey: "<YOUR_API_KEY_HERE>",
5});
6
7async function run() {
8  const result = await starton.ipfs.uploadFile({});
9
10  // Handle the result
11  console.log(result);
12}
13
14run();
15

Requirements

For supported JavaScript runtimes, please consult RUNTIMES.md.

Retries

Some of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.

To change the default retry strategy for a single API call, simply provide a retryConfig object to the call:

1import { Starton } from "@starton/sdk";
2
3const starton = new Starton({
4  apiKey: "<YOUR_API_KEY_HERE>",
5});
6
7async function run() {
8  const result = await starton.data.getBalance({
9    address: "0xc2132d05d31c914a87c6611c10748aeb04b58e8f",
10    network: "polygon-mainnet",
11  }, {
12    retries: {
13      strategy: "backoff",
14      backoff: {
15        initialInterval: 1,
16        maxInterval: 50,
17        exponent: 1.1,
18        maxElapsedTime: 100,
19      },
20      retryConnectionErrors: false,
21    },
22  });
23
24  // Handle the result
25  console.log(result);
26}
27
28run();
29

If you'd like to override the default retry strategy for all operations that support retries, you can provide a retryConfig at SDK initialization:

1import { Starton } from "@starton/sdk";
2
3const starton = new Starton({
4  retryConfig: {
5    strategy: "backoff",
6    backoff: {
7      initialInterval: 1,
8      maxInterval: 50,
9      exponent: 1.1,
10      maxElapsedTime: 100,
11    },
12    retryConnectionErrors: false,
13  },
14  apiKey: "<YOUR_API_KEY_HERE>",
15});
16
17async function run() {
18  const result = await starton.data.getBalance({
19    address: "0xc2132d05d31c914a87c6611c10748aeb04b58e8f",
20    network: "polygon-mainnet",
21  });
22
23  // Handle the result
24  console.log(result);
25}
26
27run();
28

Debugging

You can setup your SDK to emit debug logs for SDK requests and responses.

You can pass a logger that matches console's interface as an SDK option.

[!WARNING] Beware that debug logging will reveal secrets, like API tokens in headers, in log messages printed to a console or files. It's recommended to use this feature only during local development and not in production.

1import { Starton } from "@starton/sdk";
2
3const sdk = new Starton({ debugLogger: console });

Standalone functions

All the methods listed above are available as standalone functions. These functions are ideal for use in applications running in the browser, serverless runtimes or other environments where application bundle size is a primary concern. When using a bundler to build your application, all unused functionality will be either excluded from the final bundle or tree-shaken away.

To read more about standalone functions, check FUNCTIONS.md.

Summary

Starton API: Documentation: # Introduction

Starton is the all-in-one WEB3 api to integrate blockchain feature inside your project.

Authentication

To access API endpoints, you must provide a valid API key. You can create new API keys in your account settings. Be careful when handling your keys as they give access to all your project, you should treat them like passwords and they should never be committed to source control.

To authenticate with API, you can supply the API key as a header (x-api-key: YOUR_API_KEY).

Some API endpoints allow unauthenticated requests for public resources and they can be called without an API key.

Errors

All successful API requests will be returned with a 200 or 201 status code. If there’s an error while making the request, the appropriate status code is returned with the error message:

{
	"statusCode": 401,
	"errorCode": "NOT_AUTHENTICATED",
	"message": "Not authenticated",
	"timestamp": "2023-10-14T00:12:22.470Z",
	"path": "/v3/project",
	"context": {},
}

Pagination

Most top-level API resources have support for getAll API methods. For instance, you can list smart contracts, webhooks, templates etc. These list methods share common parameters, taking both limit and page.

Responses will be in the root meta and items key. For example:

{
	items: […],
	meta: {
		itemCount: 10,
		totalItems: 50,
		itemsPerPage: 10,
		totalPages: 5
		currentPage: 1
	}
}

Rate limits

Depending on your plan, you will benefit from a specific rate limit.

Plan	Rate limit
Free	50 requests/min
Developer	100 requests/min
Business	up to 10000 requests/min
