Urlbox · Rate Limits

Urlbox Rate Limits

Urlbox enforces two layers of limits: a requests-per-minute (RPM) throttle that scales by subscription tier, and a monthly render quota tied to each plan's included render allowance. Requests served from cache do not count against the render quota. Render usage is exposed on every response via x-renders-used, x-renders-allowed, x-renders-remaining, and x-renders-reset headers, and exceeding the RPM throttle returns HTTP 429.

Urlbox Rate Limits is the machine-readable rate-limit profile for Urlbox on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 6 rate-limit definitions, measuring requests and renders.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Screenshots, Rendering, PDF, Video, and Web Capture.

Monthly Render Quota account
renders
per plan allowance
Equal to the included render allowance of the active plan; over-quota usage triggers an automatic tier upgrade. Cached renders are not counted.

Policies

Cache Exemption
Requests served from the render cache do not count against the monthly render quota or RPM throttle.
Automatic Tier Upgrade
Sustained usage above the plan allowance automatically upgrades the account to the next tier.
Usage Headers
x-renders-used, x-renders-allowed, x-renders-remaining, and x-renders-reset headers report quota state on every response.
Backoff Strategy
Clients should implement exponential backoff with jitter on HTTP 429 responses.
