Free Pastebin API for AI Agents: Store & Share Text, Code, and Logs

July 11, 2026 ยท Eric ยท 5 min read

Every developer has been there: you need to share a log snippet with a teammate, save the output of a script for later inspection, or give an AI agent a place to dump intermediate results. Opening a browser, navigating to a pastebin site, pasting text, and copying a URL is tedious โ€” especially when you're already in a terminal or automating a workflow.

Agent Media Tools offers a free pastebin API at POST /api/paste that lets you create pastes programmatically โ€” from curl, Python, shell scripts, or directly from an AI agent. No signup required, no API key, no browser needed.

Why a Programmable Pastebin?

There are dozens of pastebin websites, but almost none of them offer a zero-auth REST API that works from a single curl command. Here's why that matters:

API Overview

PropertyValue
EndpointPOST /api/paste
Content-Typeapplication/json
Required fieldcontent (string, up to 500 KB)
Optional fieldstitle, syntax, expires_in_hours, is_public
ResponseJSON with slug, url, and raw_url
AuthNot required
Max size500 KB per paste

Send a JSON body with your content, get back a unique 10-character slug and a shareable URL. That's it.

curl Examples

Create a Simple Text Paste

curl -X POST https://agentmediatools.com/api/paste \
  -H "Content-Type: application/json" \
  -d '{"content": "Hello from an AI agent! This paste was created via curl."}'

Response:

{
  "success": true,
  "slug": "aB3xK9mP2q",
  "url": "https://agentmediatools.com/p/aB3xK9mP2q",
  "raw_url": "https://agentmediatools.com/p/aB3xK9mP2q/raw"
}

You can share the url with anyone โ€” it renders with line numbers and a dark theme. The raw_url returns plain text, perfect for piping into other tools.

Paste with Syntax Highlighting and Expiration

curl -X POST https://agentmediatools.com/api/paste \
  -H "Content-Type: application/json" \
  -d '{
    "content": "def hello(name):\n    print(f\"Hello, {name}!\")\n\nif __name__ == \"__main__\":\n    hello(\"World\")",
    "title": "Python hello world",
    "syntax": "python",
    "expires_in_hours": 24
  }'

This creates a paste that:

Paste from a File (Shell Scripting)

# Paste the contents of a log file
curl -X POST https://agentmediatools.com/api/paste \
  -H "Content-Type: application/json" \
  -d "$(jo content="$(cat deploy.log)" title="Deploy Log" syntax="text" expires_in_hours=48)"

Or without jo, using a heredoc:

CONTENT=$(cat deploy.log | python3 -c "import sys,json; print(json.dumps(sys.stdin.read()))")
curl -X POST https://agentmediatools.com/api/paste \
  -H "Content-Type: application/json" \
  -d "{\"content\": $CONTENT, \"title\": \"Deploy Log\", \"syntax\": \"text\"}"

Python Examples

Using only the built-in requests library โ€” no SDK or special package needed:

Create a Paste

import requests

url = "https://agentmediatools.com/api/paste"
payload = {
    "content": "Hello from Python! This paste was created programmatically.",
    "title": "Python test paste",
    "syntax": "text"
}

resp = requests.post(url, json=payload)
data = resp.json()

print(f"Paste URL: {data['url']}")
print(f"Raw URL:  {data['raw_url']}")
# Output:
# Paste URL: https://agentmediatools.com/p/aB3xK9mP2q
# Raw URL:  https://agentmediatools.com/p/aB3xK9mP2q/raw

Fetch a Raw Paste

import requests

slug = "aB3xK9mP2q"
raw_url = f"https://agentmediatools.com/p/{slug}/raw"

resp = requests.get(raw_url)
print(resp.text)
# Output: The raw paste content

Paste a File's Contents

import requests
import json

with open("error.log", "r") as f:
    content = f.read()

resp = requests.post(
    "https://agentmediatools.com/api/paste",
    json={
        "content": content,
        "title": "Error log from deployment",
        "syntax": "text",
        "expires_in_hours": 72
    }
)

paste = resp.json()
print(f"Shared error log: {paste['url']}")

Using the Pastebin API with AI Agents

This is where the pastebin API really shines. AI agents like Claude, ChatGPT, and Hermes Agent can use the pastebin as ephemeral memory โ€” dumping context, intermediate results, or long outputs they can reference later.

Agent Workflow: Summarize and Store

An AI agent processing a large document might:

  1. Read a 50-page PDF via the PDF-to-text API
  2. Generate a summary
  3. Post the summary to the pastebin
  4. Return the paste URL to the user

This pattern is especially useful in multi-turn conversations where the agent needs to pass large chunks of text between steps without exceeding context window limits.

Agent Workflow: Debug Log Collection

When an agent encounters an error running a script, it can:

  1. Capture the error output and stack trace
  2. Post it to the pastebin with syntax: "text"
  3. Return the URL with an explanation

The user gets a clean, shareable link to the full error โ€” no truncated console output.

Via MCP (for Claude Desktop/Cursor)

If you use the Agent Media Tools MCP server, you can create pastes directly from natural language:

"Take this error log and create a paste I can share with my team."

The MCP server exposes the paste_create tool, so Claude handles the JSON construction, API call, and URL response โ€” all from a simple instruction.

Use Cases Beyond the Obvious

Viewing a Paste

Every paste gets a dedicated page at /p/{slug} with:

Expired pastes return a 410 Gone status and are automatically cleaned from the database โ€” no stale links lingering forever.

Comparison: Pastebin API vs. Traditional Pastebin Services

FeatureAgent Media ToolsMost Pastebin Services
API authNone requiredAPI key or login required
curl-friendlySingle POSTOften requires cookies or tokens
Max size500 KBVaries (512 KB typical)
ExpirationOptional, in hoursOften only 1 day / 1 week / never
Syntax highlightingYes โ€” specify languageYes โ€” most support it
Rate limit100 req/day freeVaries
MCP / Agent supportBuilt-inUsually none

The key differentiator is zero-friction access. No account creation, no dashboard navigation, no API key management. Just curl -X POST with your content.

Pricing and Limits

The pastebin API is free for up to 100 paste creations per day with no authentication. Rate limits reset at midnight UTC, and the response header X-RateLimit-Remaining tells you your current status.

For higher volume needs (5,000 pastes/day), check the Developer plan at $15/month. All plans include access to the full suite of 40+ APIs.
