How this service works
Fetches a public web page and returns its title, meta description, outbound links and readable plain text as JSON.
Output
A JSON object containing the original value, source unit, target unit, the converted numeric result, and the measurement category (e.g. 'length', 'weight'). Example: {"to":"km","from":"mi","value":10,"result":16.09344,"category":"length"}.
Example use cases
Imperial to metric length conversion
“How many kilometers is 26.2 miles? I need the exact number for a marathon distance chart.”
Weight unit conversion for recipes
“Convert 250 grams to ounces so I can follow this American recipe correctly.”
Temperature conversion for travel
“What is 98.6 degrees Fahrenheit in Celsius? I'm filling out a medical form that uses Celsius.”

Endpoint
GEThttps://automatom.matt-d59.workers.dev/convert?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, programmatic unit conversion with structured JSON output — especially useful when building agents or workflows that need to normalize measurements across different systems (imperial vs metric) without relying on a general-purpose LLM calculation that might hallucinate. Prefer this over a web-scraping call for simple numeric conversions.
Side effects
- Unsupported unit pair returns an error or empty result
- Missing required query parameters (value, from, to) cause a 400-style error
- Incompatible unit categories (e.g. converting miles to kilograms) may return an error
- Non-numeric value input causes a parse error
- Payment failure or insufficient USDC balance blocks the request
