Swift Bot Labs Toolbox – Unit Converter
x402
Swift Bot Labs Toolbox – Unit Converter is a paid API for AI agents from x402-toolbox.swiftbotlab.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-31).
Converts a numeric value from one unit to another (e.g. Fahrenheit to Celsius, miles to kilometres) across multiple measurement dimensions, pay-per-call via x402/USDC.

How this service works
62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.
Output
A JSON object containing the original value and unit, the converted result (as a number), the target unit, and the measurement dimension (e.g. 'temperature', 'length', 'mass'). The 'ok' flag confirms success and 'tool' identifies 'unit-convert'.
Example use cases
Temperature conversion for weather display
“I need to show 98.6 degrees Fahrenheit as Celsius — what is that?”
Metric distance conversion for a running app
“Convert 26.2 miles to kilometres so I can display it in metric on my fitness dashboard.”
Weight conversion for a recipe tool
“My recipe calls for 250 grams of flour — how many ounces is that?”

Endpoint
GEThttps://x402-toolbox.swiftbotlab.workers.dev/v1/convert/units?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, deterministic unit conversion with no account setup or API key, and are comfortable paying $0.003 USDC per call via x402. It covers a broad range of physical dimensions. Prefer a local library if you need bulk/batch conversions or want to avoid per-call payment overhead.
Side effects
- Unsupported or misspelled unit name returns an error
- Missing required query params (value, from, to) returns a 4xx
- Incompatible unit dimensions (e.g. converting kg to metres) returns an error
- Payment failure or insufficient USDC balance returns a 402
