API & Developer Terms

Last updated: May 2026

1. Scope

These API & Developer Terms ("Developer Terms") govern access to and use of the VoxBurst REST API, webhooks, SDKs, MCP integrations, and any related developer tooling (collectively, the "API"). These Developer Terms supplement and are incorporated into the Terms of Service. In the event of a conflict, these Developer Terms control for API-related matters.

2. API access & key security

API access requires a valid VoxBurst account with API access enabled on your plan. Access is granted via API keys issued in your workspace settings.

You are responsible for:

  • Keeping API keys, tokens, OAuth credentials, and webhook secrets confidential
  • Rotating keys immediately upon suspected compromise
  • Not embedding API keys in publicly accessible code, client-side JavaScript, or public repositories
  • All activity that occurs using your API keys, including activity by your applications, integrations, and users

You must notify us immediately at contact if you believe your API key has been compromised.

3. License

FORTHEAN LABS LLC grants you a limited, non-exclusive, non-transferable, revocable license to access and use the VoxBurst API solely to build applications and integrations that interact with the Service on behalf of authorized VoxBurst workspaces. This license does not include the right to resell API access, sublicense the API, or create competing scheduling or publishing services using VoxBurst infrastructure.

4. Prohibited activity

You may not use the VoxBurst API to:

  • Build spam systems, bot networks, or tools for coordinated inauthentic behavior
  • Circumvent plan limits, rate limits, or access controls
  • Resell or redistribute API access without a written white-label agreement with FORTHEAN LABS LLC
  • Scrape or harvest data beyond what is necessary to operate your integration
  • Overload VoxBurst infrastructure with abusive request volumes
  • Access workspaces, data, or resources your application is not explicitly authorized to access
  • Reverse engineer VoxBurst's internal systems or use API responses to reconstruct proprietary logic
  • Use the API to violate connected social platform API policies, including unofficial automation restrictions

5. Rate limits & quotas

The VoxBurst API enforces per-workspace rate limits. Limits vary by plan tier and endpoint. Rate limit headers are returned with every API response — monitor X-RateLimit-Remaining and Retry-After to implement proper backoff.

Sustained abuse of rate limits may result in temporary or permanent API suspension. See the API documentation for current limit values.

6. Webhooks

Webhook endpoints you register must:

  • Respond with HTTP 200 within 10 seconds — slower responses are treated as failures
  • Be served over HTTPS with a valid TLS certificate
  • Validate the X-VoxBurst-Signature header to verify payload authenticity
  • Not expose sensitive data in webhook logs or error responses

Webhooks that fail consecutively will be automatically disabled. After 5 failures you receive a warning email; after 10 the webhook is disabled. Re-enabling resets the failure counter. See webhook documentation for details.

7. Monitoring

VoxBurst monitors API activity to detect abuse, ensure platform integrity, and enforce these Developer Terms. Monitoring data may include request volumes, IP addresses, error rates, and payload characteristics. We do not read the content of your posts through monitoring except where required to investigate a specific abuse report.

8. Connected platform rules

If your application posts content to social platforms via the VoxBurst API, you are responsible for ensuring that activity complies with those platforms' developer policies, automation restrictions, and terms of service. VoxBurst may disable API access to specific platforms if our integration is in violation of their rules — we will provide notice where possible.

9. Attribution

You may describe your product as "Built on VoxBurst" or "Powered by VoxBurst" but may not imply that your product is endorsed, certified, or officially affiliated with FORTHEAN LABS LLC without a written partnership agreement. Do not use the VoxBurst name or logo in a way that implies official endorsement.

10. Suspension & revocation

VoxBurst may suspend or permanently revoke API access without notice if your application:

  • Violates these Developer Terms or the Acceptable Use Policy
  • Creates a security risk or degrades Service performance
  • Violates connected platform API policies
  • Is the subject of a legal complaint or regulatory inquiry

We will attempt to provide advance notice of non-emergency suspensions. Emergency suspensions may occur immediately without notice.

11. No warranty on API stability

The VoxBurst API is provided "as is." We do not guarantee that API endpoints will remain unchanged indefinitely. We follow a deprecation notice period of at least 60 days for breaking changes to stable endpoints, except where immediate changes are required for security or legal compliance. Preview endpoints may change without notice.

12. Changes to these terms

We may update these Developer Terms as the API evolves. Material changes will be announced via the API changelog and by email to registered API users with at least 14 days' notice.
