I asked Claude AI to collect Google Maps data for me. Ended up with a $1,310 bill in 48 hours.

A few months ago I had a simple idea: collect a database of coffee shops in Mexico — names, phone numbers, addresses. Nothing fancy. A personal project.

I asked Claude (Anthropic's AI assistant) to help me build a script using the Google Maps Places API. Claude wrote the code, explained which API keys I needed, and told me not to worry about costs — Google gives $200-300/month in free credits, and my project would easily fit within that limit.

I set everything up, got the API keys, and ran the script.

The next day I started getting payment notifications. First a small charge — declined (insufficient funds). Then a larger one. I thought it was a glitch. Then came the final notification: $1,310.05.

In 48 hours. For a personal hobby project.

The same work done manually by a freelancer would have cost $50-100 and the data would have been higher quality.

Here's what I learned the hard way: Google Maps Platform has NO default spending cap. Unlike Google Gemini or other Google APIs which have clear quota limits, Maps Platform will charge you unlimited amounts with zero warnings until it's too late. There is no "free tier safety net."

I contacted Google support. Weeks of emails, multiple agents, escalation managers. They acknowledged it was an accidental first-time incident. They approved a 75% refund ($982.53). But $327.52 remains — and they call it a "final verdict."

The internet is full of stories where Google fully refunds accidental API overcharges for first-time users. In my case they decided 75% was enough.

I've tried everything: email escalations, Twitter @GoogleCloud, LinkedIn, Google Cloud Community, Trustpilot. Every channel either bounces me back to the same billing team or gives me an automated response.

Two lessons from this experience:

Never trust an AI assistant's cost estimates for cloud APIs. Claude was wrong. Always check the pricing page yourself and set hard budget limits before running ANY automated script.
Google Maps Platform is dangerous for independent developers and hobbyists. No default caps. No real-time warnings. One runaway script = four-figure bill.
