# Post comments

> A Reddit post and its comment thread, with nested replies.

- **Cost:** 1 credit per call. Validation errors, `401`/`402`/`429` rejections and `5xx` failures are free; `not_found` is charged ([how charging works](https://lurkapi.com/docs.md#credits)).
- **MCP tool:** `reddit_post_comments` on `https://api.lurkapi.com/mcp`
- **Freshness:** responses are cached for up to 1 minute
- **Try it live:** https://lurkapi.com/docs/reddit/post-comments#try (no signup)
- **Platform:** [Reddit](https://lurkapi.com/docs/reddit.md) (reddit.com)
- **Web page:** https://lurkapi.com/docs/reddit/post-comments

## When to use this

Use it to read a thread: the post plus comments, best first, with replies nested under `replies.items`. Where `more.has_more` is true, pass `more.next_cursor` as `cursor` with the same `url` to load more.

Good for what people really think: objections, feature requests, the words customers use.

**Loading more.** Reddit loads long threads in batches. Wherever `more.has_more` is true (at the top level, or inside any comment's `replies`), pass that `more.next_cursor` as `cursor` with the same `url` to load the batch. Cursor responses have `post: null`.

Unknown or removed posts return 404 `not_found`.

## Parameters

All parameters go in the query string.

| Name | Type | Required | Default | Allowed values | Description | Example |
| --- | --- | --- | --- | --- | --- | --- |
| `url` | string | yes |  |  | The post's URL, e.g. `https://www.reddit.com/r/marketing/comments/1wsx466/`. A /r/… path works too. | `https://www.reddit.com/r/marketing/comments/1wsx466/want_to_become_an_llm_expert_in_marketing_where/` |
| `cursor` | string | no |  |  | A `more.next_cursor` from a previous response, to load that batch of comments. |  |
| `trim` | boolean | no | `false` | `true`, `false` | `true` omits the post's `selftext_html`. |  |

    raise RuntimeError(f"{data['code']}: {data['error']}")
print(data["comments"])
```

## Pagination

Pass a cursor from a previous response as `cursor` to load more (see [When to use this](#when-to-use)). Each call costs 1 credit.

## Caching and freshness

Responses are cached for up to 1 minute, so a repeat call within that window can return the same data. It still costs 1 credit.

## Errors

Errors return `{ success: false, error, code, docs }` with the HTTP status below. Validation errors, `401`/`402`/`429` rejections and `5xx` failures are free; `not_found` is charged ([how charging works](https://lurkapi.com/docs.md#credits)). [All error codes](https://lurkapi.com/docs.md#errors).

| Status | Code | Meaning |
| --- | --- | --- |
| 401 | `missing_api_key` | No API key. Send it in the `x-api-key` header. |
| 401 | `invalid_api_key` | The key is unknown or was revoked. |
| 402 | `insufficient_credits` | Not enough credits for this call. Buy a pack or wait for tomorrow's top-up. |
| 404 | `not_found` | The endpoint, or the thing you asked for (ad, post, subreddit), doesn't exist. Charged when the platform was checked. |
| 405 | `method_not_allowed` | Endpoints take GET with query params. |
| 429 | `rate_limited` | Too many calls at once. Wait for the `retry-after` seconds, then retry. |
| 500 | `internal_error` | Something broke on our side. Retry; 5xx errors are free. |
| 502 | `upstream_error` | The platform didn't give a usable answer. Retry; 5xx errors are free. |
| 503 | `upstream_busy` | All our connections to the platform are busy. Retry in a few seconds; 5xx errors are free. |
| 504 | `upstream_timeout` | The platform took over 30 seconds to answer. Retry; timeouts are free. |

## Use it in Claude

Once LurkAPI is [connected to Claude](https://lurkapi.com/docs.md#claude), this endpoint is the `reddit_post_comments` tool. Ask in plain English, for example:

Ask Claude:

```text
Use LurkAPI's reddit_post_comments with url "https://www.reddit.com/r/marketing/comments/1wsx466/want_to_become_an_llm_expert_in_marketing_where/" and summarize what you find.
```

Claude calls `reddit_post_comments` with arguments like these, and each call costs 1 credit:

Tool arguments:

```json
{
  "url": "https://www.reddit.com/r/marketing/comments/1wsx466/want_to_become_an_llm_expert_in_marketing_where/"
}
```

Tool results skip nulls and empty lists to save tokens, and `trim` defaults to `true`.
