Pre-requisites

Get your Nevermined API Key to use the Payment libraries and REST API

To interact with Nevermined programmatically, you need a Nevermined API Key. This key is required for both:

• Payment Libraries (TypeScript SDK and Python SDK)
• REST API (direct HTTP calls)

Get Your API Key

Open nevermined.app, sign in, then go to Settings > Global NVM API Keys and click + New API Key. Copy the key and set it as an environment variable:

export NVM_API_KEY="sandbox:your-api-key-here"

Keep your API key secure. Do not commit it to version control or share it publicly.

Choose Your Environment

Nevermined offers two environments:

Environment	Purpose	Network
Sandbox	Testing and development	Base Sepolia
Live	Production	Base Mainnet

TypeScript SDK

import { Payments } from '@nevermined-io/payments'

const payments = Payments.getInstance({
  nvmApiKey: process.env.NVM_API_KEY,
  environment: 'sandbox' // or 'live'
})

Python SDK

from payments_py import Payments, PaymentOptions

payments = Payments.get_instance(
    PaymentOptions(
        nvm_api_key=os.environ['NVM_API_KEY'],
        environment='sandbox'  # or 'live'
    )
)

REST API

Environment	Base URL
Sandbox	https://api.sandbox.nevermined.app/api/v1
Live	https://api.live.nevermined.app/api/v1

curl -X GET "https://api.sandbox.nevermined.app/api/v1/protocol/agents" \
  -H "Authorization: Bearer $NVM_API_KEY"
