Request body
JSON, posted to this endpoint.
- cursorstring
Pagination cursor from a previous response's nextCursor.
- feedbackIdstring
Facebook feedback id for the post (alternative to url).
- requireFieldsarray
Optional; omit it and routing is unchanged, with the cheapest source serving. Name the output fields this request must be able to return, for example `feedbackId` or `hasNextPage`, and it is served only by a source that returns every one of them. Fields you do not name are still returned whenever the serving source has them. This can raise your price: when the cheapest source cannot return a named field, a dearer source serves, and you are quoted and charged its price. A named field can still be absent on a comment that genuinely lacks it. Naming a combination that no single source returns together is refused as invalid input, with no charge.
- urlstring
https://www.facebook.com/nasa/posts/1204545088344463
Full Facebook post URL.

MToxNzc2NDYxMjMw
Opaque cursor for the next page of comments, or null when this lane has no more. Pass it back as cursor to continue.
- foundboolean
true
True when comments were found; false when the lookup returned nothing.
- reason"not_found"
Present only when `found` is false, and says why there is no result. `not_found`: the source states the target does not exist, or returned nothing for it. A `found: false` answer is a successful call, not an error, and `costUsd` is what it actually cost.
