Body parameters

Name
url
Type
string
Required
Required
Description
The absolute URL of the page to process. Rendered with headless Chrome, so JavaScript runs and redirects are followed.
Name
report_to
Type
string
Description
Webhook URL — an http or https address URLpipe POSTs the result to when it's ready. Required for async requests (the default); omit it only when you send sync=true. A missing or invalid value returns 422.
Name
sync
Type
boolean
Description
Process the request synchronously, returning the result inline in the response. Defaults to false (async: return a token now, deliver the result to report_to via webhook). See Async & sync modes for the full contract.
Name
max_age
Type
string | integer
Description
How fresh a cached result must be to be accepted. Either an integer number of seconds (3600) or a duration string of the form "<number> <unit>" — units s/min/h/d/w (e.g. "2 hours", "3 days", "30m"). Defaults to 7 days, clamped to a max of 30 days; 0 always bypasses the cache. See Caching for all accepted units.

Response

Content type application/json — an array of strings, most relevant first.

Responses

Status

When

Body

200 OK

The request succeeded.

Sync: the result, in this endpoint's format (see Response above). Async: a job token — { "token": "…", "status": "accepted" }.

422 Unprocessable Entity

The analysis failed, or a parameter was invalid (a bad max_age, or a missing/invalid report_to in async mode).

{ "error": "<message>" }

429 Too Many Requests

You've hit your monthly quota for this operation's category (checked only on a cache miss).

{ "error": "quota_exceeded", "category", "limit", "used", "resets_at" }

504 Gateway Timeout

Sync only: the analysis didn't finish within 60s. It keeps running — fetch it via GET /result/:token.

{ "error": "processing_timeout", "token": "…" }

401 Unauthorized

Missing or invalid API key.
