GreatWait
A scheduling API for developers and their agents to make HTTP calls later, with automatic retries and full record-keeping
GreatWait is a scheduling API that makes HTTP calls at specified times with automatic retries, built for developers and AI agents.
Overview
The GreatWait homepage
GreatWait is a scheduling API that makes HTTP calls at specified times with automatic retries and full attempt record-keeping. Developers and AI agents can schedule calls to their own services or third-party APIs using the HTTP method, headers, and JSON body of their choice. The service retries failed calls with growing waits up to 5 failures, keeps every attempt on record, and integrates with AI agents through Model Context Protocol. GreatWait handles time zones with daylight saving awareness, verifies calls with cryptographic signatures, and charges only for actual attempts made.

Buyer questions
Can my agent set it all up?
Yes. Connect Claude Code, Codex or Cursor over MCP and ask in plain words. It can create schedules, read attempts and cancel what you no longer need.
Can it call someone else's API?
Yes. Point it at Slack, a CRM or a partner's endpoint you're allowed to call, with your own method, headers and JSON body.
Can it ride out a deploy?
Yes. A failed call is retried with growing waits, up to 5 failures from your app. If your app answers 429 with a Retry-After header, we wait at least that long, up to an hour.
Can my server prove the call came from you?
Yes. Every call is signed over its exact bytes with a timestamp, and signing keys can be rotated without downtime.
Can I see why something failed?
Yes. Each attempt keeps the status your server answered, the timing, and up to 10 KiB of the response.
