How this service works
One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.
Output
The endpoint returns the converted numeric value in the target unit, computed using exact conversion factors for the specified unit category.
Example use cases
Fuel economy unit conversion
“I'm looking at a European car spec that lists fuel economy as 6.5 L/100km — can you convert that to mpg for me?”
Weight conversion for shipping
“I need to know how many pounds 87.5 kilograms is — can you convert that for me?”
Data size conversion for storage planning
“How many gibibytes is 500 gigabytes? I need the exact number for a storage spec.”
Technical details
Endpoint
POSThttps://tanod.dev/v1/convert/units?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need precise, exact unit conversions across a broad range of physical and digital measurement categories, especially when accuracy matters more than approximation. Prefer it over general-purpose LLM arithmetic for verified, exact conversion factors particularly for temperature, pressure, fuel economy, and data size where rounding errors or incorrect factors are common.
Side effects
- Unsupported or misspelled unit symbol returns an error (case sensitivity matters, e.g. kB vs kb)
- Units from different categories (e.g. converting kg to km) return a category mismatch error
- Value exceeding 1e300 in magnitude is rejected
- Missing required fields (value, from, to) return a validation error
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| to | string | Unit to convert to, of the same category as `from`. |
