How this service works
Pay-per-call API for AI agents: turn any public web page or PDF into clean, LLM-ready Markdown. $0.002 per call in USDC on Base via x402. No API key, no signup.
Output
Returns a JSON object with: 'op' (the operation name, e.g. 'add'), 'meta' containing chars_in, chars_out, and elapsed_ms, and 'result' as the computed ISO 8601 datetime string in the requested timezone (e.g. '2026-10-04T19:00:00+08:00').
Example use cases
Compute subscription expiry date
“My user's subscription starts on 2025-07-01T00:00:00 UTC — what is the exact ISO datetime 30 days later in the America/New_York timezone?”
Schedule follow-up reminder offset
“I need to schedule a follow-up exactly 7 days and 7200 seconds after 2025-08-10T14:30:00 in Europe/London — what's the resulting ISO timestamp?”
Deadline calculation for a task
“A task was created at 2025-09-01T08:00:00 and is due 45 days later in Asia/Singapore time — can you compute the exact ISO deadline?”
Technical details
Endpoint
GEThttps://lin-desk-x402.lindesk.workers.dev/v1/timetools/add?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs deterministic, arithmetic datetime addition — adding a fixed number of days and/or seconds to a known datetime — especially when timezone-aware ISO output is required. Prefer it over general LLM reasoning for date math (which can hallucinate) or over full calendar APIs when you only need a simple offset computation with no scheduling side effects.
Side effects
- Invalid or unrecognized datetime input string — returns error or unexpected result
- Unknown IANA timezone string — may return error or fall back to UTC
- Non-numeric days or seconds parameter — rejected by schema pattern validation
- Missing required 'input' query parameter — request fails validation
- Network timeout on the Cloudflare Worker edge — rare but possible
