Set up periodic or one-time scheduled events via an x402-payable AI agent on Questflow.
What it does
This Questflow "Schedule" agent allows callers to create periodic or one-time scheduled events through a simple conversational interface. You send a natural-language message describing what you want scheduled (e.g., "monitor ETH price every day at 9 AM" or "remind me next Tuesday at 3 PM"), and the agent interprets the request and sets up the corresponding schedule. The agent operates in UTC time, so callers should convert from their local timezone before submitting requests.
The endpoint is an x402-enabled HTTP POST service. Payment is made via the X-PAYMENT header using USDC (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on the Base network, with a maximum cost of 0.10 USDC per call (100000 in 6-decimal units). The request body accepts a single required field, `input` (string), containing your message to the agent. The response returns a `response` string from the agent. The maximum timeout for a single call is 1200 seconds (20 minutes).
Questflow is a platform focused on autonomous AI agents for onchain markets. This particular agent is one of several specialized agents available through their x402 API. Documentation beyond the x402 challenge itself is sparse — there is no public OpenAPI spec, no dedicated docs page, and no detailed scheduling API reference. The behavior of the agent (what kinds of schedules it supports, what actions it can trigger, and how it reports back) must be inferred from the description and experimentation.
Capabilities
Use cases
- —Setting up a daily price monitoring alert for a cryptocurrency
- —Creating a weekly summary report trigger
- —Scheduling a one-time reminder for a specific date and time
- —Automating periodic checks on onchain market conditions
- —Triggering recurring data collection at fixed intervals
Fit
Best for
- —Users who need simple natural-language scheduling without building cron infrastructure
- —Agents that need to set up periodic monitoring tasks via a pay-per-call API
- —Workflows requiring one-time or recurring event triggers with UTC precision
Not for
- —Sub-second or high-frequency scheduling requirements
- —Complex multi-step workflow orchestration with branching logic
- —Users who need detailed scheduling API documentation and guaranteed SLAs

"response": "Scheduled: Monitor ETH price daily at 09:00 UTC. Your event has been created successfully."
}Endpoint
Quality
The x402 challenge is live and provides a clear outputSchema with input/output fields, payment details, and description. However, there is no OpenAPI spec, no dedicated documentation, and no examples beyond the challenge itself. The response example is inferred, not sourced. Behavior details are minimal.
Warnings
- —No public API documentation or OpenAPI spec available
- —No detailed information on what scheduled actions the agent can actually trigger
- —Response format is inferred from the outputSchema description — not from an actual successful call
- —Agent behavior and scheduling capabilities must be discovered through experimentation
