The data

On-Page data,
ready to work with.

An on-page audit is a check of one URL at one point in time. We ran this operation against our own TikTok API page: it returned the page title, a single H1, image-alt counts and the canonical URL shown in the saved response. Its only finding was informational, noting the description length against a usual range; that is a review cue, not a Google ranking rule. The endpoint also checks social tags, links, HTTPS and robots fields. It uses heuristic HTML parsing rather than a rendered browser, so JavaScript-only content or malformed markup can produce incomplete findings. Keep the URL and capture date before comparing changes.

Before you build

On-Page API questions,
answered.

Need to check a particular workflow?
Talk to us

Does this audit measure search rankings?

No. It inspects returned on-page fields and flags review items. A description-length note is not proof of a ranking effect or traffic change.

Can it fully audit a JavaScript-rendered site?

Not reliably. The operation uses heuristic HTML parsing without a headless browser. Check its warnings and inspect the rendered page separately when scripts supply important content.

What On-Page operations can I use?

The catalogue shows 1 currently available operations with their individual prices. Open an endpoint for its accepted inputs, returned fields and limitations.

How much does the On-Page API cost?

Start with 150 free credits. Paid subscriptions start at $29 per month for 10,000 credits, before applicable tax. Each operation has its own price. Check the endpoint reference for variable charges. Compare plans

How do I authenticate requests?

Use your Monocrawl API key in the x-api-key header. The endpoint reference lists any additional inputs needed for the operation. Authentication guide

What request limits apply?

Limits depend on your Monocrawl plan. The Free account ceiling is 600 requests per minute and 50 simultaneous requests. Endpoint capacity and Free daily protections also apply; these ceilings do not guarantee source throughput. Read the limits guide

What should I know about On-Page coverage?

The audit uses heuristic HTML parsing; JavaScript-rendered or malformed pages may produce incomplete findings. An informational length note is a review cue, not a Google ranking rule or proof of poor search performance.
