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 square kilometers, the converted value in square feet (IEEE-754 double precision), the source and target unit labels ('square-kilometer' and 'square-foot'), and the dimension type ('area').
Example use cases
Real estate land area conversion
“I have a property listed as 0.85 square kilometers — what is that in square feet so I can compare it to US listings?”
Geographic region size calculation
“A nature reserve covers 12.3 square kilometers; can you tell me how many square feet that is?”
Construction project area verification
“The site plan says the development area is 0.042 square kilometers — convert that to square feet so the contractor can use it.”

Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/area/square-kilometer-to-square-foot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, precise, single-call conversion from square kilometers to square feet with IEEE-754 double precision and a structured JSON response. It is ideal for agents automating unit normalization in real estate, geospatial, or construction data pipelines where micro-payment per call is acceptable and a dedicated conversion service is preferred over general-purpose math.
Side effects
- Negative or non-numeric value provided — schema requires minimum 0
- Missing required 'value' query parameter returns validation error
- Values exceeding 1e+100 are rejected by schema maximum constraint
- Payment not included or insufficient USDC results in 402 Payment Required response
- Service unavailability on Cloudflare Workers edge returns 503
