Authentication

All Developer API endpoints require an API key. You can pass your key in one of two ways:

x-api-key header (recommended)

curl https://api.anonpaste.com/api/dev/pastes/get/aB3xYz \
  -H "x-api-key: your_api_key_here"

Authorization: Bearer header

curl https://api.anonpaste.com/api/dev/pastes/get/aB3xYz \
  -H "Authorization: Bearer your_api_key_here"

The SDK always uses x-api-key internally.

Error responses

Status	Reason	Description
401	API key required	No key was provided
401	Invalid API key	The key doesn’t match any account
429	Monthly limit reached	Free quota exhausted and no credits available

Keeping your key safe

• Never expose your API key in client-side JavaScript or public repositories
• If a key is compromised, regenerate it from Settings → Developer — the old key is immediately invalidated
• For server-side applications, store the key in an environment variable:

export ANONPASTE_API_KEY="your_api_key_here"

import { AnonPaste } from 'anonpaste-sdk';

const anonpaste = AnonPaste.init({
  apiKey: process.env.ANONPASTE_API_KEY!,
});
