How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
A JSON object containing the original value in astronomical units, the converted value in kilometers (IEEE-754 double precision), the source and destination unit labels, and the measurement dimension (length).
Example use cases
Space mission distance planning
“I need to know how many kilometers away 0.72 astronomical units is — that's roughly the distance to Venus. Can you convert that to km?”
Astronomy homework calculation
“My homework problem says a comet is 3.2 AU from the Sun — how many kilometers is that?”
Exoplanet orbit distance conversion
“Convert 5.2 AU to kilometers for me — that's Jupiter's orbital distance and I want the exact km figure for a chart I'm making.”

Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/length/astronomical-unit-to-kilometer?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise, programmatic conversion from astronomical units to kilometers, especially in agent workflows that require exact IEEE-754 double-precision numeric results rather than approximate human-readable estimates. It is suitable for single-value conversions in space science, astronomy, or educational contexts.
Side effects
- Missing or non-numeric 'value' query parameter returns an error
- Negative value rejected (minimum is 0 per schema)
- Value exceeding 1e+100 rejected (maximum constraint)
- Payment not provided or invalid results in 402 Payment Required
- Network timeout on Cloudflare Worker execution
