cURL - Generate UUIDs
curl -X POST https://toolknife.com/api/v1/tools/uuid-generator_generate-v7 \
  -H "Content-Type: application/json" \
  -d '{"count": 5}'

# Response:
# { "uuids": ["019...abc", "019...def", ...], "version": 7 }
Python - Hash and verify
import requests

BASE = "https://toolknife.com/api/v1/tools"

# Generate bcrypt hash
bcrypt_hash = requests.post(f"{BASE}/bcrypt-generator_hash", json={
    "text": "my-secret-password",
    "rounds": 12,
}).json()["result"]["hash"]

# Generate HMAC signature
hmac = requests.post(f"{BASE}/hmac-generator_generate", json={
    "text": "request-body-to-sign",
    "key": "api-secret",
    "algorithm": "SHA-256",
}).json()["result"]["hmac"]

print(f"Bcrypt: {bcrypt_hash}")
print(f"HMAC: {hmac}")
JavaScript - JSON formatting and validation
const res = await fetch(
  "https://toolknife.com/api/v1/tools/json-formatter_format",
  {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({
      input: '{"name":"John","age":30,"cities":["NYC","LA"]}',
      indent: 2,
    }),
  }
);

const { result } = await res.json();
console.log(result.formatted);
