How this service works
Web standards and time reference for AI agents: HTTP status codes with what the client should do, retry semantics, MIME types and content-type matching, request-method safety and idempotency, plus deadline arithmetic - time until a moment, weekday and business-day checks, duration conversion and Unix timestamps. Pay per call in USDC on Base via x402 or USDC on Tempo via MPP. No signup, no API key, no KYC.
Output
Returns the converted numeric duration in the requested target unit, e.g. given value=3600, from=seconds, to=hours the result is 1.
Example use cases
Deadline math in a scheduling agent
“I have a task that takes 90 minutes — how many seconds is that? Convert 90 minutes to seconds.”
Normalizing API timeout values
“Our API returns timeouts in milliseconds, but I need to display them in seconds — convert 45000 milliseconds to seconds.”
Log analysis duration normalization
“Convert 2 weeks into days so I can compare it against an integer day-count I got from another API.”
Technical details
Endpoint
GEThttps://webref.johnaio281.workers.dev/api/time/convert_duration?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to programmatically convert a duration between standard time units (milliseconds through weeks) without writing custom arithmetic, especially in agentic pipelines where consistent unit normalization is needed and you want a pay-per-call model with no API key setup.
Side effects
- Missing required 'value' query parameter returns an error
- Invalid or unsupported unit enum value for 'from' or 'to' returns a validation error
- Non-numeric value parameter causes a schema validation failure
- Network or worker downtime results in a 5xx response
