Postman Setup Guide

Get Postman ↗

Get a free API key at alphavantage.co/support/#api-key — instant, no credit card
Create a new GET request to https://www.alphavantage.co/query
In the Params tab add: function = GLOBAL_QUOTE, symbol = AAPL, apikey = YOUR_KEY
You can use apikey = demo for the AAPL and IBM symbols only
Send — look for Global Quote in the response for the latest price
Tip: save your key as a Postman variable {{av_key}} to reuse across requests

What can you build with Alpha Vantage?

Alpha Vantage is a Company API. Developers commonly use company APIs for:

enriching CRM records with company firmographics
building lead-generation and prospecting tools
verifying business identity and registration details
monitoring competitors and market intelligence
powering B2B data enrichment pipelines

API Key authentication. You'll receive a key after signing up. Send it with every request — in a header or query parameter. Keep it out of client-side code and never commit it to version control.
