Response#

A Collection object in data.

See Data models for every field. The envelope around data is described in Responses.

Errors#

Failures are free: credits_charged is 0. Branch on error.code, never on the message.

Code	HTTP	Retry	Meaning
`invalid_params`	400	no	A parameter is missing, unknown or has the wrong type.
`unsupported_url`	400	no	The URL is not one this endpoint accepts (wrong platform or form).
`not_found`	404	no	The platform says this profile, post or item does not exist.

Every request can also fail with the account and platform errors listed on the Errors page.

Example error:

1{2  "ok": false,3  "error": {4    "code": "not_found",5    "message": "The platform says this profile, post or item does not exist.",6    "retryable": false7  },8  "credits_charged": 0,9  "request_id": "req_b0943aa2575e1fc37cebb76a"10}
