Limitations

The HacknPlan Public API is rate-limited to 5 requests per second per IP.

When exceeded, requests return 429 Too Many Requests.

For production usage, implement a queue plus retry policy so delayed calls can be retried safely.

Recommendations

• API operations affect real production data, including while in beta. Test carefully.
• Avoid distributing public integrations that depend on beta endpoints; breaking changes may occur.
• Protect API keys and avoid sharing them with untrusted third parties.
• Use separate API keys per integration or workflow.
• Grant the minimum scopes required by each key.

This model improves security and lets you revoke one integration without disrupting others.
