CoinGecko Terminal / TS SDK

OpenAPI + TypeScript + Type Safe API

Summary

This package provides a type-safe SDK for interacting with the CoinGecko Terminal API. The main feature is a strongly typed API client generated using OpenAPI 3 specs. The repository is open source and hosted at In This GitHub Repository.

Check out the Changelog to see what changed in the latest releases.

Important Note: This SDK only Support ESM (ECMAScript Modules).

Quick Start

Install the SDK

You can install the CoinGecko Terminal SDK using Bun:

bun add geckoterm

Use the SDK

Here's an example of how to use the SDK to fetch the available networks:

import { getNetworks, setGeckotermAPIConfg } from 'geckoterm'

// Set the config for the client with the Base URL and API key
setGeckotermAPIConfg({
  baseUrl: 'https://api.geckoterminal.com/api/v2',
  // Replace with your API key / if you have one
  headers: {
    Authorization: `Bearer ${process.env.GECKOTERM_API_KEY}`,
  },
})

// Use the internal method to call the API
const response = await getNetworks({
  query: {
    page: 1,
  },
})

// Log the response
console.log('API response data:', response.data)

Install dependencies for Contributions

Prerequisites

Before running the SDK, ensure you have the following dependencies installed:

• Bun (optional, but recommended): Used for runtime and testing.

You can install the required dependencies as follows:

Install Bun (for testing primitives, not required for the SDK itself)

# Supported on macOS, Linux, and WSL
curl -fsSL https://bun.sh/install | bash

# Upgrade Bun occasionally
bun upgrade

Compile API Client

To generate the TypeScript client from the OpenAPI spec, run the following commands:

# Step 1: Install dependencies
bun install

# Step 2: Compile the API client
bun run compile:api

The compile:api command performs the following steps:

• Uses the @hey-api/openapi-ts Generator CLI to generate the TypeScript API client from the OpenAPI 3 spec.
• Formats the generated code using Prettier.
