Summary
Handles timezone conversions and lists all IANA timezone identifiers through a remote API. The server runs over SSE transport and integrates x402 micropayments, meaning you'll pay per request. Useful when you need to convert datetimes across zones in your Claude workflows without maintaining timezone data locally or writing conversion logic yourself. The implementation is straightforward: convert times between named zones and query the full IANA timezone database. Reach for this when you're building scheduling tools, coordinating across global teams, or processing timestamped data that needs timezone awareness. The micropayment model makes sense for occasional timezone operations where you'd rather outsource the complexity than bundle a full timezone library.

Timezone Converter API
Convert datetime between timezones -- all IANA zones, UTC offset, DST-aware. ISO 8601 input/output. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.
Quickstart -- MCP
Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):
{
"mcpServers": {
"timezone-converter": {
"url": "https://timezone-converter.api.klymax402.com/mcp"
}
}
}
Quickstart -- HTTP (x402)
curl -X POST "https://timezone-converter.api.klymax402.com/api/convert" \
-H "Content-Type: application/json" \
-d '{"datetime":"...","from":"...","to":"..."}'
# -> 402 Payment Required, with an x402 payment challenge in the response body
Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.
