Quick start
- Create an account and verify your email.
- Paste this line into your AI agent (Claude, ChatGPT, Cursor…). When you are logged in it already includes your key:
set up zyla with key YOUR_API_KEY - https://zylalabs.com/llms.txt
- Ask for what you need in plain words, for example "What's the weather in Madrid?" or "Validate this list of emails". Your agent finds the right API and calls it.
Building your own software instead? Pick an API in the catalog, subscribe to a plan and call it with your key. Every API page shows the request already filled in, with code samples in 15 programming languages. See Call an API over HTTP.
