HTML/CSS to Image · Rate Limits

Htmlcsstoimage Rate Limits

HTML/CSS to Image meters usage by the number of images rendered per month against the account's plan allowance. Concurrency and request throughput limits apply to protect the rendering infrastructure; once a plan's monthly image allowance is reached, additional images are billed as overages rather than hard-blocked. Specific per-plan throughput and concurrency values are not reconciled in this artifact.

Htmlcsstoimage Rate Limits is the machine-readable rate-limit profile for HTML/CSS to Image on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 3 rate-limit definitions, measuring images, concurrent_requests, and requests.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Image Generation, HTML to Image, Rendering, Templates, and Rate Limiting.

Policies

Overage Billing
Images beyond the monthly allowance are billed as overages at $10 per 1,000 images rather than rejected.
Backoff Strategy
Clients should implement exponential backoff with jitter and honor Retry-After on 429 responses.
Usage Visibility
The GET /v1/usage endpoint returns hourly, daily, and monthly usage so clients can track consumption against the plan allowance.
