📊 API Rate Limits & Overage Policy

Aptly enforces API usage limits to ensure reliability and fairness across all tenants. These limits vary by subscription tier and are monitored on a per-tenant basis.

​
🚦 Plan Tiers & API Limits

PlanMonthly API Call LimitRate Limit (per Minute)Description
Essential25,00060 calls/minuteIntended for basic integrations.
Premium100,000300 calls/minuteIdeal for mid-sized organizations.
Enterprise250,000600 calls/minuteScalable for enterprise integrations.

​
💰 API Overage Pricing

PlanOverage Fee (per API Call)Notes
Essential$0.005Hard cap at 50,000 calls/month. Upgrade required to exceed this.
Premium$0.005Billed in 1,000-call blocks once 100k calls/month is exceeded.
Enterprise$0.003Billed in 1,000-call blocks after 250k calls/month.
Example: If a tenant on an Enterprise plan makes 300,000 calls in a month:
  • Included: 250,000 calls
  • Overage: 50,000 × 0.003=∗∗0.003 = **150/month** → $1,800/year

​
🚨 Enforcement & Fair Use

  • Burst Handling: Short bursts up to 2× the per-minute rate are allowed to support sync operations and multi-threaded workflows.
  • Rate Limit Breaches: Requests beyond monthly or per-minute limits return a 429 Too Many Requests response, with a Retry-After header indicating when to retry.
  • Per-Tenant Enforcement: Limits apply per tenant, regardless of how many API keys are issued. Issuing multiple tokens does not increase capacity.
  • Real-Time Monitoring: API usage can be monitored from the “Admin Portal > Integrations > API Usage” section.

​
🛡️ Authentication & Token Management

  • You can issue multiple API keys per tenant to support different integrations.
  • All keys share the same cumulative limit based on the subscription tier.
  • For authentication details, see API Authentication.

​
🔁 Retry Strategy

When receiving a 429 Too Many Requests response:
  • Respect the Retry-After header (in seconds).
  • Implement exponential backoff with jitter to prevent synchronized retry loops.
  • Example 429 response body:
{
  "status": 429,
  "error": "Too Many Requests",
  "message": "Monthly API limit exceeded. Contact support to upgrade your plan.",
  "retry_after": 60
}

​
🧪 Development & Testing Environments

If you require a non-production environment for development or testing, contact support to request a sandbox tenant. Usage in development environments is isolated and does not count toward production API quotas. For questions about rate limits or to discuss higher-tier options, contact your Aptly account representative or support.
