How this service works
USDC pay-per-call APIs for AI agents via the x402 protocol (v2, exact, Base mainnet). Send a request, receive HTTP 402 with payment requirements, pay with @x402/fetch or any x402 client, retry with the PAYMENT-SIGNATURE header.
Output
A JSON object containing the ISO UTC datetime string, Unix timestamp in milliseconds, Unix timestamp in seconds, Asia/Shanghai formatted local datetime, and an echo of the original Unix seconds input if provided.
Example use cases
Log timestamp normalization for an agent
“I have a log entry with the date '2025-10-21' and I need the Unix timestamp in both seconds and milliseconds so I can index it correctly — can you convert that for me?”
Cross-timezone scheduling check
“What is the Asia/Shanghai local time equivalent of Unix timestamp 1761004800? Also give me the ISO UTC string so I can double-check the conversion.”
Epoch to human-readable date for a report
“I've got a Unix timestamp of 1761004800 that appears in a data export — can you convert it to a readable ISO date string and tell me what time that is in UTC?”
Technical details
Endpoint
POSThttps://call402.com/api/timestamp-convert?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs rapid, deterministic conversion between ISO date strings and Unix epoch timestamps, especially when multi-timezone output (UTC + Asia/Shanghai) is needed simultaneously. Prefer this over building date math locally when the agent environment lacks reliable datetime libraries or when operating in a pay-per-call context on Base mainnet via x402.
Side effects
- Missing or malformed input (neither date nor timestamp provided) results in a 400 error
- Invalid ISO date string format causes a parsing failure
- Ambiguous timestamps (seconds vs milliseconds not inferable) may produce incorrect conversions
- HTTP 402 returned on first request requiring USDC micropayment via x402 protocol before the response is served
- Network timeout if payment signature is not attached within the retry window
