APIMesa is a pay-per-call API marketplace. Instead of juggling five different subscriptions, dashboards, and billing plans, you get one API key and one credit balance that works across the whole catalog. Every API shows its exact credit cost up front, and every API has an interactive playground so you can test it in the browser before you write a line of code.

🚀 How it works

1. Get your API key at apimesa.com — sign up and your key is ready in seconds.
2. Pick an API from the directory below (170 APIs across 54 categories).
3. Call it with your key — credits are deducted per call, only when the call succeeds.

curl -X POST "https://apimesa.com/api/v1/contact-extract" \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text": "Reach Jane Doe at [email protected]"}'

⭐ Star this repo

If this directory saves you time, give it a star ⭐ — it helps other builders find it.
