I Built a Trade Pricing API That Covers 5 Countries — So AI Agents Stop Hallucinating Contractor Costs

Ask ChatGPT "how much does a plumber cost in California?" and you'll get a vague range from 2021 wrapped in disclaimers. Ask Claude the same thing and it'll tell you to "check local listings." That's the problem. LLMs don't have access to structured, current pricing data. So they guess. And when your AI agent guesses the cost of a $15,000 roof replacement, someone loses money. I built an API to fix that. What it does The Trade Pricing API returns verified contractor and tradesperson pricing across 5 countries — Australia, United States, United Kingdom, Canada, and New Zealand. 10 trades. 30+ services. 700+ price records. 30+ states/regions. All with source attribution. Trades covered: Plumber, Electrician, Carpenter, Painter, Roofer, HVAC, Landscaper, Cleaner, Locksmith, Pest Control.
