What is Glasser?

Glasser is a pay-as-you-go API platform that gives AI agents access to premium data sources through a single API key and balance. It aggregates 1,900+ endpoints from 40+ providers covering people, companies, SEO, social, funding, email, places and pricing data. Instead of subscribing to each vendor separately, agents can discover, price and call the right endpoint on demand.

How to use Glasser?

1. Copy the setup prompt from the site and paste it into your agent (Claude, Codex, Cursor, etc.); the Skill installs the CLI and guides you through login. 2. Sign up and get a $1 signup grant with no card required. 3. Search the catalog to find the right endpoint for your task. 4. Run the call — the provider and price are shown before execution and the final charge after. 5. Pay per call from one balance; failed calls and empty results cost $0.00.
