Reddit API — Getting Started — FetchLayer Docs

Getting Started

Get your first API call working in under two minutes.

1. Get your API key

Sign up for a FetchLayer account and generate an API key from the dashboard. Free tier included — no credit card required.

2. Make your first request

Call any endpoint with curl, or use the TypeScript SDK.

curl

bash
curl -X POST https://api.fetchlayer.dev/reddit/search \
  -H "Authorization: Bearer ss-your-key" \
  -H "Content-Type: application/json" \
  -d '{"query":"developer tools","sort":"top","limit":5}'

TypeScript SDK

npm install @fetchlayer/reddit

typescript
import { FetchLayer } from '@fetchlayer/reddit';

const client = new FetchLayer({ apiKey: 'ss-your-key' });

const { items } = await client.search({
  query: 'developer tools',
  sort: 'top',
  limit: 10,
});

Tip

The free tier covers a generous number of requests per month with no credit card required — plenty for testing before you commit to a paid plan.

3. Understand the response

Every endpoint returns structured JSON. Listing endpoints return entries in items together with pagination and billing details.

json
{
  "listingType": "search",
  "query": "developer tools",
  "items": [
    {
      "id": "1wi3mi5",
      "title": "Is vibe coding creating a hidden technical debt crisis?",
      "subreddit": "webdev",
      "author": "powleads",
      "score": 3241,
      "commentCount": 418,
      "url": "https://www.reddit.com/r/webdev/comments/1wi3mi5/",
      "createdAt": "2026-08-13T03:00:00.000Z"
    }
  ],
  "itemCount": 1,
  "pagesRequested": 1,
  "pagesScraped": 1,

}

Error responses

Every error, on every route, is JSON in one shape: error (what went wrong, in words), status, code, retryable and requestId, which also comes as the X-Request-Id header. Branch on code and retryable rather than on the text; on a 5xx the text is generic. Quote requestId when reporting a problem.

json
{
  "error": "Missing required parameter: url",
  "status": 400,
  "missing": ["url"],
  "code": "invalid_input",
  "retryable": false,
  "requestId": "922874e3-c0d0-40d8-8866-d198af132420"
}
codeStatusRetryableMeaning
invalid_input400noThe request needs fixing; error names the field. A missing required parameter also lists it in missing.
unauthorized401noThe API key is missing or not valid.
insufficient_credits402noNothing left to spend: no credits, a used-up free trial, or a monthly allowance and credit balance both spent. error says which. Waiting does not help; topping up does.
forbidden403noThis key or account is not allowed this request.
not_found404noWhat the request names does not exist or is not public.
expired410noWhat the request refers to is no longer available; ask for it afresh.
quota_exceeded429noA request-rate limit was reached; error says which. Slow down before sending more.
cancelled499noThe caller closed or cancelled the request before it finished. The work was stopped and nothing was charged.
time_limit503yesYour timeoutMs ran out before there was anything to return; ask again, or allow more time.
temporarily_unavailable503yesNot available right now; ask again shortly.
posts_unavailable403noTikTok user videos: TikTok is not showing this account’s posts publicly right now. Asking again at once returns the same answer; nothing is charged.
store_unreachable503yesStore routes (Shopify, WooCommerce): the store itself can’t be reached right now — it may be offline. Ask again later. Where a store route doesn’t say so yet, an offline store is temporarily_unavailable.
upstream_error502yesThe source answered in a way that could not be used; ask again later.
internal_error500yesSomething failed on our side; ask again later, and quote requestId if it persists.
tool_error—noMCP only: a tool call failed in a way no other code describes; error says what.

More codes may be added; treat one you do not recognise by its retryable flag. Over MCP, a tool error carries the same fields in structuredContent, and as a JSON text block beside the message.
