I Built One Key for All the Data My AI Agents Kept Asking For

Originally published on Medium.

My agents kept running into the same wall. They needed live data like Google results, keyword volume, Maps places or an exchange rate, and each source wanted its own signup, its own key and usually a monthly plan. For a few calls a week, that's a lot of setup.

How it works

1ToolRing is one key and one prepaid balance. The agent describes the job, gets matching tools with their prices, inspects the one it wants, then runs it. Over MCP that's discover_tools, then inspect_tool, then run_tool. Every price is shown before the call.

What it costs

You pay per call, with no plan. A Google search is about Rp48 (roughly $0.003). Failed calls are free. You can top up any amount: from Rp10.000 in rupiah by bank virtual account or minimarket, or from $1 by card.

The parts I kept strict

For now the catalog covers search and SEO, Maps, e-commerce prices, crypto and exchange rates. People data, email finding, social data and scraping are not offered. Every run's cost is held up front, so an agent can't overspend.

Setup

Paste this into Claude Code, Codex, Cursor or ChatGPT:

set up 1ToolRing - https://1toolring.com/llms.txt

The agent adds the server and you sign in once in the browser. There's no key to copy.

Early access

I'm approving accounts in batches to keep costs in check. Approved accounts start with Rp10.000 to try it.
