> Comments on a post with the first levels of replies (parent_id says which comment a reply answers): text, commenter, score and reply count. Reddit's default order, newest or top score first.

Canonical page: https://okdata.online/apis/reddit/posts/comments/list/

- **Endpoint**: `GET /v1/reddit/posts/comments/list`
- **ID**: `reddit.posts.comments.list`
- **Price**: $0.002 per call · about 10 comments per page
- **Returns**: a page of about 10 comments (`data.items`, Comment objects)
- **Status**: preview
- **Good for**: Word of mouth

## Price

One call costs $0.002 and returns one page of about 10 comments. Collecting 1,000 comments takes about 100 calls, $0.20 in total. Each page is a separate call; failed calls are not charged.

## Parameters

| Name | Type | Required | Default | Description |
|---|---|---|---|---|
| `id` | string | no |  | The post ID, with or without the t3_ prefix. Give id or url. (e.g. `t3_1nnrvkr`) |
| `url` | string | no |  | A share link or page URL; the ID is read from it. (e.g. `https://www.reddit.com/r/nasa/comments/1nnrvkr/`) |
| `sort` | string: best / latest / popular | no | `best` | Result order. |
| `cursor` | string | no |  | Opaque cursor from page.next_cursor of the previous call. Each page is a separate call. |
| `view` | string: compact / standard / full | no | `standard` | How much of each object comes back. full adds platform-specific fields under ext. |
| `fields` | string[] | no |  | Fields to keep, by path (author.name), to save tokens. In a query string: comma-separated. |

Give id or url; one of the two is enough. 
cursor, view and fields work as described in [Requests](https://okdata.online/docs/requests/).

## Returned fields

Each item is a [Comment](https://okdata.online/docs/objects/comment/).

| Field | Type | Description |
|---|---|---|
| `id` | string | Comment ID. |
| `post_id` | string | ID of the post it is under. |
| `parent_id` | string \| null | The comment it replies to; null for top-level comments. |
| `text` | string | Comment text. |
| `published_at` | string | When it was posted, ISO 8601 in UTC. |
| `author` | AccountRef | Who wrote it. |
| `likes` | integer \| null | Likes on the comment. |
| `replies` | integer \| null | Replies under it. |
| `ip_location` | string \| null | Region label the platform shows next to the comment, if any. |
| `ext` | object | Platform-specific extras. Only returned with view=full. |

## Errors

Errors share one shape: code, request_id, message and message_zh (a fixed sentence per code), charged, retry, retry_after_seconds, param and docs_url, with the specifics in problems. They are not charged; only settlement_unknown is unknown until looked up. The full table: https://okdata.online/docs/errors/

## Questions

### How much does the Reddit post comments API cost?

One call costs $0.002 and returns one page of about 10 comments. Collecting 1,000 comments takes about 100 calls, $0.20 in total. Each page is a separate call; failed calls are not charged.

### How do I get the next page?

Pass page.next_cursor from the response back as the cursor parameter. When page.has_more is false there is nothing left. Every page is its own call at $0.002.

### Do I need a Reddit account, cookies or a QR login?

No. You send only your okdata API key. The data is public data from Reddit; nothing is fetched with your own Reddit account.

### Am I charged when a call fails?

No. Every error response says charged: false, except a timeout, which says charged: null until the outcome is known. Resend with the same Idempotency-Key and you are never charged twice.

### What if Reddit does not show a field?

The field is null, and meta.unavailable names it with the reason: platform (the platform never shows it) or capability (we cannot fetch it yet).

Prices from price book 1b273c48fea9634e. [Every price on this platform](https://okdata.online/pricing/reddit/)

- New accounts get $0.10 of credit, no card needed: 50 calls to this endpoint.
- About 100 calls fetch 1,000 comments: $0.20 in all.

## Known limits

- About 10 comments come back per page; the platform sets the page size, so there is no page-size parameter.
- For the next page, pass `page.next_cursor` back as `cursor`. A cursor stays valid for 24 hours. When `page.has_more` is false there is nothing left.
- Give exactly one of `id`, `url`.

## Fields by view

The view column is the smallest `view` a field comes back in: `compact` returns only compact fields, `standard` adds the standard ones, `full` returns everything. The default is `standard`.

- `compact`: `id`, `post_id`, `parent_id`, `text`, `published_at`, `author`, `likes`, `replies`
- `standard`: `ip_location`
- `full`: `ext`

## Common errors on this endpoint

| HTTP | Code | Meaning | Charged | Retry |
|---|---|---|---|---|
| 400 | `invalid_params` | A parameter is missing, has the wrong type or value, or the method is wrong. problems lists each one; param names the first. | no | after a fix |
| 400 | `cursor_mismatch` | The cursor was sent to another endpoint, or with other parameters than the page it came from (view and fields may change). | no | after a fix |
| 401 | `unauthorized` | The key is missing, malformed, revoked, disabled or expired (reason says which when known). | no | no |
| 402 | `insufficient_balance` | The balance (available) cannot cover the most this call could cost (required). | no | after a fix |
| 404 | `not_found` | The post, account or page does not exist or is not public. Endpoints whose charge_when_not_found is above 0 charge this answer (the source billed us for it): the body then says charged: true and amount. | no | no |
| 410 | `cursor_expired` | The cursor is older than the endpoint's cursor lifetime (page.cursor_expires_at said when). | no | no |
| 429 | `rate_limited` | The account sent too many requests this minute (reason: rate) or has too many calls running (reason: concurrency). | no | yes |
| 500 | `settlement_unknown` | The data came back, but the charge could not be confirmed. | unknown until looked up | with the same Idempotency-Key |
| 502 | `upstream_failed` | Every data source for this endpoint failed on this request. | no | yes |
| 503 | `capability_paused` | This endpoint is paused right now; nothing ran. | no | yes |
| 504 | `timeout` | The data did not come back in time. The hold was released, so nothing was charged. | no | yes |
