Rate Limits
IPWho enforces rate limits to keep the platform reliable and fast for everyone. Limits apply in two layers: a daily quota (by plan) and a burst cap (all plans).
Plan Limits (daily)
Section titled “Plan Limits (daily)”| Plan | Daily requests | Notes |
|---|---|---|
| Free | 2,000 / day | Personal, testing, and non-profit use. Hard limit applies. |
| Launch Special | 5,000 / day | Good for early-stage projects. |
| Startup | 250,000 / day | Designed for higher-throughput production workloads. |
| Enterprise | Unlimited* | Subject to fair use and contract terms. |
*Enterprise daily limits are governed by fair use and contractual commitments. If you need guaranteed throughput, contact us.
Burst Limit
Section titled “Burst Limit”Separate from the daily quota, every plan is subject to a burst limit of up to 100 requests per second (100 QPS).
When you exceed the burst limit, the API responds with HTTP 429 and:
{ "error": "burst_limit_exceeded", "message": "Burst rate limit exceeded. Slow down and retry shortly."}Spread traffic evenly when possible. If you need sustained throughput above the burst cap, contact us.
What Happens If You Exceed Limits
Section titled “What Happens If You Exceed Limits”| Limit | HTTP | error code | Typical message |
|---|---|---|---|
| Burst (up to 100 QPS) | 429 | burst_limit_exceeded | Burst rate limit exceeded. Slow down and retry shortly. |
| Daily quota | 429 | daily_quota_exceeded | Daily request quota exceeded. Try again tomorrow or upgrade your plan. |
Free plan users who hit the daily quota may be prompted to upgrade to continue.
