x402
Timestamp Converter (Unix ↔ ISO-8601) is a paid API for AI agents from api.24klabs.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).
Converts between Unix epoch timestamps (seconds or milliseconds) and ISO-8601 datetime strings, and reports the weekday and UTC offset.

How this service works
Convert between Unix epoch (s/ms) and ISO-8601; report weekday and UTC offset.
Output
Returns the converted timestamp in the target format (Unix epoch seconds/milliseconds or ISO-8601 string), along with the weekday name and UTC offset for the given point in time.
Example use cases
Logging timestamp human-readable display
“I have a Unix timestamp 1698765432 in seconds from our server logs — can you convert it to ISO-8601 and tell me what day of the week that was?”
API response date normalization
“Convert the ISO-8601 string '2024-03-15T14:30:00Z' to a Unix epoch timestamp in both seconds and milliseconds so I can store it in our database.”
Epoch milliseconds from frontend event
“Our frontend is sending event timestamps in milliseconds — convert 1711497600000 ms to a readable ISO-8601 datetime and tell me the UTC offset and weekday.”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/timestamp-convertWhen to prefer
Use this endpoint when an agent needs to reliably convert between machine-readable Unix timestamps and human-readable ISO-8601 strings, or when it needs to determine the weekday or UTC offset for a given point in time. Prefer this over manual computation or LLM inference, which can be error-prone for timestamp arithmetic.
Side effects
- Invalid or out-of-range epoch value returns a 4xx error
- Malformed ISO-8601 string that cannot be parsed returns a validation error
- Ambiguous timezone or missing UTC offset may result in UTC assumption
- Extremely large epoch values (beyond year 9999) may be rejected
