Do I need an API key?

No. The publish endpoint is open and free, with fair-use rate limits. An API key option for higher limits can come later.

Can ChatGPT or Claude use this?

Yes. Add the publish action to a ChatGPT custom GPT using the schema at api.snapy.host/openapi.json, and the GPT can host what it makes and return the link. Any AI agent that can make an HTTP request can use it too.

A JSON response with the live link, a private analytics link, and a token. You can open the link right away.

Developers and AI

Publish from code or an AI in one call

snapy has a simple API so a script or an AI assistant can publish what it makes and hand back a link, with no account and no setup.

The publish API

Send the content you generated and get a live link back in one request. No file upload form, no account, just JSON.

POST https://api.snapy.host/api/publish
Content-Type: application/json

{
  "content": "<!doctype html><h1>Hello from an AI</h1>",
  "filename": "index.html",
  "name": "my-demo"
}

content is the text or HTML to publish. filename is optional and sets the type (defaults to index.html). name is optional and sets the link name. For a binary file, send content_base64 instead of content.

You get back:

{
  "url": "https://my-demo.snapy.page",
  "stats_url": "https://snapy.host/a/XXXX",
  "token": "XXXX"
}

url is the live link to share. stats_url is your private page to see views and downloads. Open the link right away.

Try it with curl

curl -X POST https://api.snapy.host/api/publish \
  -H "content-type: application/json" \
  -d '{"content":"<h1>It works</h1>","name":"hello"}'

Use it from a ChatGPT custom GPT

This is the fun part. You can give a custom GPT the power to host what it builds and reply with a link.

In ChatGPT, create or edit a custom GPT and open the Actions area.
Import the schema from https://api.snapy.host/openapi.json.
Save. Now when you ask the GPT to build a page, it can publish it and give you a working link.

Use it from any AI agent or script

It is a plain HTTP POST, so anything that can make a web request can use it: a Python or Node script, a no-code tool like Zapier or Make, or an autonomous agent. The agent builds something, calls the endpoint, and shares the link it gets back.

Limits

Up to 100MB per file.
Fair-use rate limits per client.
Free to use right now, with no account.

Step-by-step guides for each tool

There is a short how-to for every popular tool in the integrations section:

ChatGPT custom GPT action
Claude MCP connector
Zapier, Make, and n8n automation
Python and JavaScript scripts

MCP server for Claude

A dedicated MCP server lets assistants like Claude call snapy as a built-in publish tool. See the Claude integration guide for how to add it.
