Search Reddit

When to use this

Use it for brand monitoring and to find where a topic is discussed. It searches posts across all of Reddit, like reddit.com/search, and returns each post's title, author, subreddit, score, comment count and date. It doesn't search comments.

Results have no body text or link. For the full post, pass https://www.reddit.com + permalink as url to post comments (reddit_post_comments).

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

Example request

Copy one and replace YOUR_API_KEY with your API key (get one free). The code versions read the key from the LURKAPI_API_KEY environment variable instead.

curl "https://api.lurkapi.com/v1/reddit/search?query=claude+mcp" \
  -H "x-api-key: YOUR_API_KEY"

const params = new URLSearchParams({
  query: "claude mcp",
});
const res = await fetch(`https://api.lurkapi.com/v1/reddit/search?${params}`, {
  headers: { "x-api-key": process.env.LURKAPI_API_KEY },
});
const data = await res.json();
if (!data.success) throw new Error(`${data.code}: ${data.error}`);
console.log(data.posts);

    headers={"x-api-key": os.environ["LURKAPI_API_KEY"]},
    timeout=60,
)
data = res.json()
if not data["success"]:
    raise RuntimeError(f"{data['code']}: {data['error']}")
print(data["posts"])

Parameters

Add them to the URL after a ?, as in ?query=claude+mcp. Join several with &.

Example response

A real response, captured from the live API. Lists are trimmed to a couple of items, and long text such as media links is cut short with ….

Response fields

Every field in a successful response, and what it means. A name with [] belongs to each item of a list: posts[].id is the id of every item in posts. null means there's no value.

Pagination

Results come in pages. For the next page, repeat the call with the same parameters and add the response's after as after. On the last page, after is null. Each page costs 1 credit.

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?${params}`, {headers: { "x-api-key": process.env.LURKAPI_API_KEY },});const data = await res.json();if (!data.success) throw new Error(`${data.code}: ${data.error}`);console.log(data.posts);after = data.after;if (!after) break; // last page}

Cost and freshness

Each call costs 1 credit. Calls turned away before they reach the platform (invalid parameters, a key or balance problem, a rate limit) are free, and so are 5xx errors. A not_found is charged, since the platform was checked. How charging works.

Answers are cached for up to 1 minute. A repeat call within that time can return the same data, and costs the same.

Errors

A failed call returns success: false, an error message, a code your program can check, and a docs link. These are the errors this endpoint can return. All error codes.

Use it in Claude

Connect LurkAPI to Claude and ask in plain English. This endpoint is the reddit_search tool. For example:

Use LurkAPI's reddit_search tool with query "claude mcp", then summarize what you find.

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

{"query": "claude mcp"}

To save tokens, tool results leave out empty fields, keep one URL per image or video, and give transcripts as plain text unless you pass timestamps=true. A result over 45,000 characters comes in parts. Its _note gives the offset for the next part, and later parts are free for 15 minutes. Pass trim=false for the full response.
