TypeScript SDK for the E3D API and wallet-side E3DToken swap helpers.

Full documentation → docs.e3d.ai

Install

npm install e3d-sdk

Build

npm install
npm run build

Quick start

import { E3D } from 'e3d-sdk';

const e3d = new E3D({ apiKey: process.env.E3D_API_KEY });

const openApi = await e3d.discovery.getOpenApi();
const rate = await e3d.discovery.getRate();
const token = await e3d.tokens.getTokenProfile('0x6488861b401F427D13B6619C77C297366bCf6386');

Modules

• discovery - schema, rate, newsletter
• tokens - token discovery, metadata, price history, token page bundle
• swap - wallet-side E3D trading helpers
• stories - story feeds and story-linked discovery helpers
• theses - thesis feed and annotation/candidate helpers
• tokenIntelligence - counterparties and batch metadata
• auth - API key management

Examples

• JavaScript examples live in examples/
• Python examples live in examples/python/
• Go examples live in examples/go/
• The Python examples use only the standard library and are safe to run without extra dependencies
• The Go examples use only the Go standard library and are safe to run without extra dependencies

Swap example

import { E3D } from './dist/index.js';
import { ethers } from 'ethers';

const e3d = new E3D({
  swap: {
    defaultRouterVersion: 3,
  },
});

const provider = new ethers.providers.Web3Provider(window.ethereum as any);
const signer = provider.getSigner();

const tx = await e3d.swap.buyE3D(
  { provider, walletAddress: await signer.getAddress(), signer },
  { inputToken: 'ETH', amountIn: ethers.utils.parseEther('0.05').toString(), slippageBps: 100 }
);
console.log(tx.hash);

Notes

• This SDK intentionally treats /agents as experimental and does not include it in v1.
• Swap support is wallet-side only; there is no server buy/sell endpoint.
• The package is designed to work with the live E3D deployment and its /openapi surface.
