Rate limits
Each plan has a daily allowance of lookups, counted across all your keys and reset at 00:00 UTC.
| Plan | Lookups a day |
|---|---|
| Free key | 50 |
| Archive | 20,000 |
| Live | 100,000 |
Only calls that return data count. A refused call (a typo, a plan limit, a missing ID) costs nothing, and neither does Usage.
Headers on every counted call
| Header | Meaning |
|---|---|
X-RateLimit-Limit | Your daily allowance. |
X-RateLimit-Remaining | What is left after this call. |
X-RateLimit-Reset | When the count resets, as a Unix time. |
When the allowance is used, calls return 429 daily_limit with resets_utc and a Retry-After header in seconds.
