🤖 Call from AI Agents & Scripts

Every tool is callable via a plain GET request — perfect for agents (Claude, GPT, custom workflows) that need deterministic utilities:

# Repair broken JSON returned by a model curl "https://capabilitybase.com/tools/json-repair.html?input=%7B%22a%22%3A%201%2C%7D" # Count tokens before an API call curl "https://capabilitybase.com/tools/word-counter.html?text=Hello%20world" # Decode a JWT without uploading it anywhere curl "https://capabilitybase.com/tools/jwt-decoder.html?input=eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiIxMjMifQ.sig" # Generate 10 UUID v4s curl "https://capabilitybase.com/tools/uuid-generator.html?version=v4&count=10"

All processing happens in the browser of the requesting client — no server-side state, no logs, no API keys.

🧪 Deterministic Contract

🔒 Privacy Guarantee

100% client-side processing. Your data never leaves your browser — no uploads, no tracking, no server-side logs. Safe for production configs, proprietary JSON, and auth tokens.
