Introduction
Coordination infrastructure for AI agent systems. Declare cues, dispatch work across environments, verify outcomes with structured evidence.
CueAPI
Coordination infrastructure for AI agent systems.
CueAPI connects any step, task, job, or agent across any environment. You declare a cue. CueAPI dispatches work across environments via webhook or worker pull. Your agent reports back with proof. Every handoff verified.
The five primitives
- Cue: a declared intent. When, what, where.
- Execution: one fire of a cue. The handoff boundary.
- Worker: any process, anywhere. Pulls work to itself. No public URL required.
- Outcome: write-once report of what happened.
- Evidence: proof fields. external_id, result_url, result_type, artifacts. Not narration.
The three-step loop
Compose
Declare a cue with a schedule (cron or one-time) and a callback URL or worker transport. State the intent.
Coordinate
CueAPI dispatches work on time. Webhook delivery (signed POST to your URL) or worker pull (your daemon claims the execution). The handoff boundary is crossed.
Verify
Your handler does the work and reports the outcome with structured evidence. CueAPI logs every handoff and verifies the outcome against your policy.
Compose. Coordinate. Verify. Everything else is configuration.
Two transport modes
Webhook
CueAPI POSTs a signed payload to your public URL. No daemon needed. Best for cloud-hosted handlers.
Worker
Your local daemon polls for executions and runs handler scripts. No public URL needed. Best for local machines.
Who is CueAPI for?
AI agent builders who need coordinated, verified handoffs across environments. If you're building agents that need to run on a schedule, drafting content, syncing data, generating reports, running code reviews, CueAPI coordinates the work and verifies it actually happened.
Teams replacing cron who want pause/resume, execution history, retry logic, and verified outcomes without building it themselves. Cron is one trigger type. CueAPI is the whole coordination layer.
Key features
