How this service works

The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.

Output

Returns an object with ok:true and an items array containing the created schedule's scheduleId, status, nextFire timestamp, everySeconds interval, maxFires limit, expiresAt timestamp, and callbackSigner public key used to verify signed callbacks. Also includes a source object with provider, URL, and license metadata.

Example use cases

Daily digest trigger for an agent pipeline

“Create a recurring schedule that POSTs to https://myapp.example.com/hooks/digest every 3600 seconds with payload {"job":"digest"}, label it 'daily-digest', and stop after 30 fires.”

One-shot reminder callback at a future time

“Schedule a one-time callback to https://myapp.example.com/hooks/reminder at 2026-07-01T09:00:00Z with payload {"alert":"meeting-start"} and label it 'team-meeting-reminder'.”

Recurring health-check heartbeat

“Set up a recurring webhook to https://myapp.example.com/healthcheck every 60 seconds with payload {"check":"heartbeat"}, max 1000 fires, and label it 'heartbeat-monitor'.”

When to prefer

Choose this endpoint when you need a lightweight, pay-per-call, keyless scheduler that delivers signed HTTP callbacks either once at a precise future timestamp or on a recurring interval. It is ideal for AI agent workflows that need timed triggers without maintaining their own cron infrastructure. Prefer it over self-hosted cron or managed job queues when you want zero setup, USDC micropayment billing, and cryptographically signed callbacks for verification.

Side effects

Providing both 'at' and 'everySeconds' simultaneously returns a validation error
'at' timestamp in the past may be rejected
everySeconds below 60 is rejected as below minimum
callbackUrl missing or malformed returns a validation error
maxFires above 1000 is rejected
expiresInSeconds below 60 is rejected
Payment failure or insufficient USDC balance prevents schedule creation
Callback URL unreachable at fire time results in a missed delivery with no retry guarantee
