How this service works
Private PDF preflight and authorized-video intelligence APIs paid per call with x402 USDC on Base.
Output
Returns a JSON object with a jobId, the converted numeric result (e.g., 2.2046 for 1 kg to lb), the conversion factor used, a human-readable formula string (e.g., 'value * kilograms-per-kg / kilograms-per-lb'), the input echo (value, from, to), a schema version, and a source hash for auditability, plus economics fields showing the $0.001 USDC cost breakdown.
Example use cases
Shipping weight label conversion
“I need to convert 4.5 kg to ounces for a shipping label — can you do that?”
Recipe ingredient scaling
“This recipe calls for 200 grams of flour, but I need to know how many ounces that is.”
Fitness tracker unit switch
“I weigh 185 pounds — what is that in kilograms and also in stone?”
Technical details
Endpoint
GEThttps://x402.bakdupoffroad.com/v1/utility/convert-weight?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, auditable weight conversion with a verifiable formula and conversion factor — especially in automated pipelines where reproducibility and a source hash matter. It supports 8 common weight units (mg, g, kg, oz, lb, stone, metric-ton, short-ton) and is priced at $0.001 USDC per call via x402, making it suitable for high-frequency agent workflows where traceability is valued over a free but opaque conversion.
Side effects
- Missing required query parameters (value, from, to) returns a validation error
- Unsupported unit enum value causes a 400 bad request
- Value outside the ±1,000,000,000,000 range is rejected
- Payment not provided or insufficient USDC results in a 402 Payment Required response
