StatusUnknown

How this service works

Pay $0.10 USDC to schedule a one-shot webhook delivery. Provide a URL and a delay in seconds — the server fires a signed POST to your URL when the timer expires. Automatic retries on failure (up to 3 attempts). Network: Base Mainnet. Each request creates one delayed webhook job and returns identifiers for status checks and cancellation.

Output

Returns a job identifier for status polling and a cancellation identifier. When the timer expires, the server fires a signed POST request to the provided URL. If the initial delivery fails, the system automatically retries up to 3 times before marking the job as failed.

Example use cases

Example prompt

“Schedule a webhook to fire a signed POST to https://myapp.example.com/hooks/payment-confirmed in 300 seconds — I need it to retry up to 3 times if it fails, and give me back a job ID so I can cancel it if needed.”

Technical details

Endpoint

POSThttps://cron.0000402.xyz/schedule?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need a simple, pay-per-use one-shot delayed webhook without managing your own cron infrastructure. Ideal for lightweight automation, deferred callbacks, post-payment confirmations, or any scenario requiring a timed HTTP trigger with retry guarantees and cancellation support, especially in agentic workflows operating on Base Mainnet with USDC micropayments.

Side effects

Invalid or unreachable webhook URL causes delivery failure and exhausts all 3 retries
Delay value of zero or negative seconds may cause immediate or rejected scheduling
Payment failure on Base Mainnet results in job not being created
Webhook target URL returns non-2xx responses triggering retries
Job not found when querying status if incorrect job identifier is used

Reviews

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
