Rate Limits

Rate limits are applied per tier. Sandbox access is anonymous and keyed by IP address — no account needed. Authenticated tiers use your API key.

Tier	Identifier	Daily limit	Burst	Access
Sandbox	IP address	100 req / day	20 per 10s	Free, no signup
Builder	API key	1,000 req / day	—	Free, get key
Scale	API key	Unlimited	—	Request via dashboard

Rate limit headers

Limits reset at midnight UTC each day. When a limit is exceeded, the API returns 429 Too Many Requests:

{
  "error":  "rate limit exceeded",
  "code":   "RATE_LIMITED",
  "status": 429
}

Builder keys get 1,000 requests per day. If you need more, request the Scale tier from your dashboard — unlimited requests, same low latency.
