Errors and outcomes

HTTP status codes

Status	Meaning
`400`	Invalid JSON, body or URL (`unsupported_url` for private or non-HTTP targets).
`401`	Missing, unknown or revoked API key.
`402`	`insufficient_credits`, or a `max_credits` below the mode's base price (`ceiling`).
`403`	`account_blocked`, or stealth mode on a trial account.
`409`	The `Idempotency-Key` was reused with a different body.
`410`	The result was deleted or has expired.
`429`	An account limit; retry after the `Retry-After` header.
`503`	Temporary capacity limit; retry shortly.

A failed job costs nothing. Its error explains which kind of failure it was:

`error`	What happened
`blocked`	Every allowed level was refused, or the site requires real authentication.
`too_large`	The page needed more transfer than `max_credits` allows.
`extraction_failed`	The page loaded but held no usable content, or never finished rendering.
`attempts_exhausted`	Transient failures used up the retries.
`timeout`	The execution budget ran out.
`queue_expired`	The job waited too long for capacity.
