Comments

per_call

Returns nested comments for a post including body text, author, score, depth, gilded status, edited flag and timestamps, with sort options and cursors for deep threads. A staple for product-feedback mining and sentiment research.

What you get

Each call returns up to 20 comments, plus a cursor for the next 20.

Endpoint

Price

$1.50

per 1,000 calls · $0.0015 per call

Cost per call

1 credit

Failed calls never charged

Parameters

target
required
string

The Reddit post — its id or the full URL.

limit
optional
integer

Maximum records to return, capped at this service's page size (see Limits below). Omit it to receive the whole page. It shapes the response, not the price — a call costs the same either way.

cursor
optional
string

Pagination cursor returned by a previous response.

fresh
optional
enum

Bypass cached data and force a live fetch for this one call. Use it for daily monitoring or any figure you are tracking over time. Accepts `true`, `1`, `false` or `0`; anything else returns 400 `invalid_fresh`. Defaults to false and costs exactly the same as a cached call.

One of: true, 1, false, 0

Example request

Live call. Successful calls are charged; failed and empty results are not.

Getting more results

Each response includes a cursor. Pass it back as cursor to fetch the next 20 comments. Repeat until no cursor is returned.

Limits

  • Maximum per call: 20 comments.
  • Minimum per call: 1 comment — a target with less data returns fewer comments, and an empty result is still a successful call.
  • Pass limit to receive fewer than 20 comments. It shapes the response, not the price.
  • Larger jobs are paginated with a cursor; there is no cap on how many pages you fetch.

What this costs in practice

200,000 comments = 10,000 calls × 1 credits per call = 10,000 credits = $0.00

Priced at the Custom pack rate: 1,000,000 credits for $0.00.

Error codes

401invalid_api_keyMissing or unrecognized X-API-Key header. No credits are charged.
402insufficient_creditsYour balance is below the cost of the call. Top up to continue.
403account_suspended / key_revokedThe account is suspended or the key was revoked.
429rate_limitedOver your account's requests-per-second limit. Retrying helps: the body carries retry_after_seconds and the response carries a Retry-After header. Not charged.
429monthly_cap_reachedThis key used the monthly call cap you set for it. Retrying will not help — raise the cap, use another key, or wait for the next calendar month. No Retry-After header is sent. Not charged.
500upstream_errorUnexpected failure while fulfilling the request. Not charged.
