Miscellaneous Utilities

Null

Simple null value generator that returns JSON null via GET /v1/misc/null. Useful for AI agents testing null handling, filling template gaps, or resetting variables in workflows. Perfect for MCP tools in Cursor or Claude Code when you need an explicit null rather than undefined behavior.

API Endpoint

GET /v1/misc/null

Code Examples

curl "https://tinyfn.io/v1/misc/null" \
  -H "X-API-Key: YOUR_API_KEY"
const response = await fetch('https://tinyfn.io/v1/misc/null', {
  headers: { 'X-API-Key': 'YOUR_API_KEY' }
});
const data = await response.json();
console.log(data);
import requests

response = requests.get('https://tinyfn.io/v1/misc/null',
    headers={'X-API-Key': 'YOUR_API_KEY'})
data = response.json()
print(data)

FAQ

What does the null tool return exactly?

Returns JSON null value with 200 status. The response body is literally `null` with Content-Type application/json.

When would I use this instead of just typing null?

Useful for AI agents that need deterministic null values, testing null handling in workflows, or when MCP tools require explicit API calls rather than hardcoded values.

Does this work with conditional logic in AI coding assistants?

Yes, perfect for Cursor or Windsurf when you need null as a fallback value or default state in generated code patterns.

Is there any difference between this null and JavaScript null?

No difference in value. This returns standard JSON null, identical to JavaScript null when parsed.

Can I use this to reset variables or clear data?

Absolutely. Great for clearing form fields, resetting API payloads, or providing null defaults in data processing workflows.
