Endpoint
POSThttps://omni-api-cyan.vercel.app/api/tools/convert/speedWhen to prefer
Use this endpoint when you need a quick, pay-per-call speed unit conversion without setting up a local library. Suitable for agents that occasionally need speed conversions across mph, km/h, m/s, and knots without embedding a full math library. Cost is ~$0.045 USDC per call via x402.
Side effects
- Unsupported or unrecognized unit names return an error or null result
- Malformed query string without clear source/target units may return unexpected output
- Non-numeric input values may cause conversion failure
- Missing 'query' field returns a validation error since it is required
