Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/cron/next?expr=*%2F15%209-17%20*%20*%20MON-FRI"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/cron/next?expr=*%2F15%209-17%20*%20*%20MON-FRI&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum, Monad, World Chain or Tempo) and retries.

Example result

{
  "expr": "*/15 9-17 * * MON-FRI",
  "next": [
    "2026-10-19T09:00:00.000Z",
    "2026-10-19T09:15:00.000Z"
  ]
}
