Rate limits - Perceptlayer

Limits apply per account, shared by all its keys, and are counted in fixed one-minute windows.

Account	Requests a second	Requests a minute
Free	1	60
Paying, at least	5	300
Paying, fastest pack rate	300	18,000

Paying accounts run at the rate of the credits they are using. Credits bought at a faster rate are used first; when they run out, the account returns to the rate of its other credits. You choose a rate when you buy a pack. See pricing.

Headers

Every authenticated response, errors included, carries the account’s current position:

Header	Meaning
`RateLimit-Limit`	Requests a minute for the account
`RateLimit-Remaining`	Requests left in the current minute
`RateLimit-Reset`	Seconds until the current minute resets
`RateLimit-Policy`	`<requests a minute>;w=60`

Over the limit

Over the limit you get 429 rate_limited with a Retry-After header in seconds, the same value as RateLimit-Reset. It’s never billed. Wait that long and retry, or spread calls out using RateLimit-Remaining.
