Rate Limits & Quotas

Rate Limits & Quotas

ADCG enforces rate limits per API key to ensure fair usage and platform stability. Limits vary by plan tier.

Plan Limits

Plan	Requests/Minute	Concurrent Runs	Evidence Retention
Free	50	2	30 days
Standard	200	10	1 year
Professional	600	50	3 years
Enterprise	2,000	Unlimited	Unlimited

Per-IP Default

Unauthenticated requests (e.g., health checks, OpenAPI spec) are limited to 200 requests/minute per IP.

Rate Limit Headers

Every response includes rate limit information:

X-RateLimit-Limit: 200
X-RateLimit-Remaining: 187
X-RateLimit-Reset: 1708012380

Header	Description
X-RateLimit-Limit	Maximum requests allowed in the current window
X-RateLimit-Remaining	Requests remaining in the current window
X-RateLimit-Reset	Unix timestamp when the window resets

Throttling Behavior

When you exceed your rate limit:

1. The API returns 429 Too Many Requests
2. The Retry-After header indicates how many seconds to wait
3. Requests are not queued — they are rejected immediately
4. Rejected requests do not count against your limit

{
  "error": {
    "code": "RATE_LIMITED",
    "message": "Rate limit exceeded. Retry after 12 seconds.",
    "retryAfter": 12
  }
}

Quota Tracking

Beyond rate limits, some resources have monthly quotas:

Resource	Free	Standard	Professional	Enterprise
Pipeline runs	100/mo	1,000/mo	10,000/mo	Unlimited
Evidence storage	1 GB	10 GB	100 GB	Unlimited
Webhook endpoints	2	10	50	Unlimited
API keys	2	10	50	Unlimited

Upgrade Paths

If you're hitting limits:

1. Check usage — GET /v1/usage shows current consumption across all quotas
2. Optimize — Batch operations where possible, cache read-heavy responses
3. Upgrade — Contact sales or upgrade through the dashboard at /pricing

Enterprise customers can negotiate custom limits tailored to their workload.
