How this service works
Convert Unix seconds, Unix milliseconds, or date strings into ISO, Unix seconds, Unix milliseconds, and UTC fields without calling an upstream model. Pay up to $0.001 per request with x402 USDC on Base. Public paid calls are limited to 1500 input characters and 128 output tokens.
Output
Returns a JSON object with ok status, tool name ('timestamp'), a fetchedAt field indicating when the request was processed, and a summary of the conversion result including the converted or formatted date/time value.
Example use cases
Example prompt
“Convert the Unix timestamp 1716825600 to a readable ISO date — I want to know what date and time it corresponds to in UTC.”
Technical details
Endpoint
GEThttps://gpt55.558686.xyz/v1/tools/timestampWhen to prefer
Use this endpoint when you need lightweight, pay-per-call timestamp conversion without a subscription, especially in agentic workflows that use x402 USDC micropayments on Base. Ideal for one-off conversions where spinning up a full date library is overkill and cost per call must be minimal ($0.0001 USDC).
Side effects
- Missing or invalid 'value' query parameter returns an error response
- Insufficient USDC balance for x402 payment results in 402 Payment Required
- Invalid timestamp format may return a parsing error
- Network or gateway downtime returns 5xx error
- Non-numeric or unparseable input value causes tool failure
