When to use this

Use it for brand monitoring and finding where a topic is discussed. Results have no body text or link; pass https://www.reddit.com + permalink as url to post comments (reddit_post_comments) for the full post. Posts only, no comment search.

Site-wide post search, like reddit.com/search: title, author, subreddit, score, comment count and date.

Pagination. Pass the response's after back as after; it's null at the end.

Response fields

Every field of a successful response. [] marks a list: a[].b is the b of each item in a. nullable fields can be null; optional fields can be missing.

Pagination

Pass the response's after back as after, with the other parameters unchanged, for the next page. It's null on the last page. Each page costs 1 credit.

The first five pages, in JavaScript
let after = null;
for (let page = 1; page <= 5; page++) {
  const params = new URLSearchParams({ query: "claude mcp" });
  if (after) params.set("after", after);
  const res = await fetch(`https://api.lurkapi.com/v1/reddit/search?${params}`, {
    headers: { "x-api-key": process.env.LURKAPI_KEY },
  });
  const data = await res.json();
  if (!data.success) throw new Error(`${data.code}: ${data.error}`);
  console.log(data.posts);
  after = data.after;
  if (!after) break; // last page
}

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). All error codes.

StatusCodeMeaning
401missing_api_keyNo API key. Send it in the x-api-key header.
401invalid_api_keyThe key is unknown or was revoked.
402insufficient_creditsNot enough credits for this call. Buy a pack or wait for tomorrow's top-up.
405method_not_allowedEndpoints take GET with query params.
429rate_limitedToo many calls at once. Wait for the retry-after seconds, then retry.
500internal_errorSomething broke on our side. Retry; 5xx errors are free.
502upstream_errorThe platform didn't give a usable answer. Retry; 5xx errors are free.
503upstream_busyAll our connections to the platform are busy. Retry in a few seconds; 5xx errors are free.
504upstream_timeoutThe platform took over 30 seconds to answer. Retry; timeouts are free.

Use it in Claude

Once LurkAPI is connected to Claude, this endpoint is the reddit_search tool. Ask in plain English, for example:

Ask Claude
Use LurkAPI's reddit_search with query "claude mcp" and summarize what you find.

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

Tool arguments
{
  "query": "claude mcp"
}

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