Terms of Service
Last updated: April 10, 2026 · Operated by Vector Apps Inc.
These Terms of Service (“Terms”) govern your use of CueAPI, coordination infrastructure for AI agent systems operated by Vector Apps Inc. (“we”, “us”, “our”). By using CueAPI, you agree to these Terms.
1. The Service
CueAPI provides a coordination API that lets you register tasks (cues), deliver them via webhooks or local workers, retry on failure, and verify execution outcomes. The service includes the REST API, dashboard, CLI, and documentation.
2. Account Registration
You must provide a valid email address to create an account. You are responsible for keeping your API key secure. One account per person or organization.
3. Acceptable Use
You may use CueAPI only for lawful purposes. Your use of CueAPI is subject to our Acceptable Use Policy, which is incorporated into these Terms by reference. Key restrictions include (but are not limited to):
- Send webhooks to URLs you do not own or control
- Access or attempt to access other users' data
- Circumvent usage limits or rate limits
- Use the service for DDoS or load testing against third parties
- Transmit illegal payloads
- Resell the service without permission
- Reverse-engineer the service
- Interfere with service operation
For a complete list of prohibited uses, enforcement procedures, and how to report violations, see the full Acceptable Use Policy.
4. Plans and Pricing
4.1 Free Tier
10 active cues, 300 executions per month, 60 API requests per minute. No credit card required. Free forever.
4.2 Paid Plans
Pro: $9.99/month or $95.88/year. Scale: $49/month or $470.40/year.
4.3 Plan Changes
Upgrades take effect immediately. Downgrades take effect at the end of the current billing period. Excess cues are paused, not deleted.
4.4 Refunds
No partial refunds for unused portions of a billing period.
5. Usage Limits and Enforcement
When you reach your monthly execution limit, CueAPI provides a 24-hour grace period. During grace, cues continue firing. After 24 hours, executions are blocked until the next billing cycle or an upgrade. Rate limit exceeded responses return HTTP 429 with a Retry-After header.
6. Service Level
6.1 Availability
CueAPI does not guarantee a specific uptime percentage. Current status is available at status.cueapi.ai. The system is designed so that failures delay delivery but never lose a schedule.
6.2 Delivery Guarantee
At-least-once delivery. Your handler may receive the same execution more than once. Use execution_id as your deduplication key.
6.3 Maintenance
Planned maintenance is announced on the status page.
7. Data and Privacy
Your data is handled as described in our Privacy Policy (v2, April 10, 2026). Key points:
- API keys are stored as SHA-256 hashes
- Webhook payloads are signed with HMAC-SHA256 using per-user secrets
- All API traffic requires HTTPS
- Data is stored on Railway infrastructure in the United States
- We use 7 sub-processors — see our Sub-Processor Disclosure Page
If you process personal data through CueAPI and need a formal data processing agreement, see our Data Processing Agreement.
8. Your Data Rights
You have the right to access, export, correct, and delete your data:
- Access: GET /v1/auth/me/processing
- Export: GET /v1/auth/me/export
- Update: PATCH /v1/auth/me
- Delete: DELETE /v1/auth/me (requires X-Confirm-Destructive: true)
Account deletion initiates a 24-hour grace period. You will receive a confirmation email with a cancellation link. After 24 hours, all data across all tables is permanently and irreversibly deleted. An audit record is retained with one-way hashes only (no reversible PII).
For full details on GDPR and CCPA rights, see our Privacy Policy.
9. Intellectual Property
You retain all rights to your data. CueAPI retains all rights to the service, API, documentation, and related intellectual property.
10. Limitation of Liability
