# Bly.to > Bly.to is a fast link shortener with custom domains, analytics, QR codes, and a REST API. Create short `bly.to` links — or brand them on your own subdomain — for marketing, Instagram, business campaigns, and AI agents. Bly.to (also styled Blyto) shortens long destination links into memorable short links, tracks clicks and QR scans separately, and offers a developer API at `https://bly.to`. Connect a custom subdomain (CNAME to `cname.bly.to`) for branded short links. New accounts receive 200 free credits; each new link costs 1 credit. Credits never expire. ## Product - [Home](https://blyto.com/): Overview of Bly.to — short links, custom domains, analytics, and QR codes - [Features](https://blyto.com/features): Link shortening, custom domains, analytics, QR codes, and API - [Pricing](https://blyto.com/pricing): Credit-based pricing ($1 per 50 credits; $10–$500 per checkout) - [FAQ](https://blyto.com/faq): Short links, custom domains, analytics, credits, API, account, and safety ## Use cases - [AI Agents](https://blyto.com/ai-agents): Short links for LLM and agent outputs — fewer tokens, custom domains via API - [Business](https://blyto.com/business): Campaign links, custom domains, branded sharing, and click insights - [Instagram](https://blyto.com/instagram): Short links, QR codes, and custom domains for bio, Stories, and posts - [Developers](https://blyto.com/developers): REST API docs — create links, custom domains, analytics, QR codes (`X-API-Key`) ## Company & trust - [About](https://blyto.com/about): Product background - [Security](https://blyto.com/security): Security practices and threat checks - [Contact](https://blyto.com/contact): Support and inquiries - [Report a link](https://blyto.com/report): Report abusive or malicious short links - [Privacy](https://blyto.com/privacy): Privacy policy - [Terms](https://blyto.com/terms): Terms of service ## Optional - [Full AI context](https://blyto.com/llms-full.txt): Extended product facts, API overview, and FAQ highlights
