What you can do with APITemplate.io in Claude and ChatGPT

For developers and ops teams who generate PDFs and images with APITemplate.io.

See which templates you have saved

The AI lists your PDF and image templates with id, name, format and group, and reads the HTML and CSS of a PDF template.

Check how many generations you have left

The AI reads your quota: generations allowed, used and remaining, plus the template count. Check it before a big batch.

Review the files you generated

The AI lists generated PDFs and images, newest first, with template, type, your meta reference and the hosted file URLs.

Generate a PDF or image from a template

The AI fills a saved template with your JSON data, or changes the layers of an image template, and returns the hosted download URL.

Changes data

Turn HTML, Markdown or a web page into a PDF

The AI renders a PDF from HTML or Markdown with placeholders filled from data, or prints a public web page, and returns the download URL.

Changes data

Merge several PDFs into one

The AI joins 2 to 20 PDFs from public URLs, in the order you give, and returns the URL of the merged PDF. The source files stay unchanged.

How do I connect APITemplate.io?

Before you connect

The login page asks for your APITemplate.io API key and Region.

Copy the key in the APITemplate.io web console (app.apitemplate.io, API Integration). Choose the region your account uses: templates and files live in one region, and a key only works on its own region's host. If you are unsure, keep the default (Singapore). Your key is used only to call the APITemplate.io API on your behalf; it is never shown to anyone.

In Plugins, install APITemplate.io, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http apitemplate https://apitemplate.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "apitemplate": {
      "url": "https://apitemplate.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "apitemplate": {
      "type": "http",
      "url": "https://apitemplate.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add apitemplate --url https://apitemplate.usefulapi.io/mcp

codex mcp login apitemplate

Other clients

Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.

https://apitemplate.usefulapi.io/mcp

Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your APITemplate.io API key and Region. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

Pricing

Plan	Price	Limit
Free	$0	50 tool calls / month
Proper user	$9/mo · $90/yr	10,000 tool calls / month
Pro+per user	$39/mo · $390/yr	100,000 tool calls / month

Each paid plan covers this APITemplate.io server only. Ask your AI to run apitemplate_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with apitemplate_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with apitemplate_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Your usefulapi plan · 4

Usage status (free-tier meter)apitemplate_usage_status
Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter.
Request a missing featureapitemplate_request_feature
Tell usefulapi that the user needs something the APITemplate.io tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter.
Upgrade to Pro or Pro+apitemplate_upgrade
Get a paid plan for APITemplate.io (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
Cancel the Pro subscriptionapitemplate_cancel_subscription
Cancel the caller's APITemplate.io Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run apitemplate_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with APITemplate.io in Claude or ChatGPT?

See which templates you have saved. Check how many generations you have left. Review the files you generated. Generate a PDF or image from a template. Turn HTML, Markdown or a web page into a PDF. Merge several PDFs into one. See what you can do for the details.

Is this an official APITemplate.io product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by APITemplate.io. The server calls the APITemplate.io API with your own APITemplate.io access, so it sees only the data that your account can see.

Can I connect APITemplate.io to Claude or ChatGPT?

Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.

What do I need to connect?

The login page asks for your APITemplate.io API key and Region. See Before you connect for where to find them.

Do I put my APITemplate.io key or an Authorization header in the client config?

No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your APITemplate.io API key and Region. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

How do you keep my APITemplate.io credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the APITemplate.io API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in APITemplate.io.

Can the AI change my APITemplate.io data?

Yes, if you approve it. 6 of the 10 APITemplate.io tools can create or change data. The other 4 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this APITemplate.io server only. Cancel any time: your paid plan then runs to the end of the paid period. Run apitemplate_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run apitemplate_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run apitemplate_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a APITemplate.io tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with apitemplate_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.

Which AI clients can I use?

Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.

Need a tool this server does not have, or a connection to another system? We build custom integrations and MCP servers.
