Why SerpKite

What every API key gets

Markdown output, strict parameters, spend caps per key, and refunds for every failed or empty search.

01

Official SDKs

Typed clients for TypeScript, Python and Go, plus native LangChain and CrewAI tools. Retries, timeouts and batch polling built in.

02

Credits never expire

Packs stack and stay on your balance until you spend them. You pay per pack, with no subscription.

03

LLM-ready output

Ask for format=markdown or compact and project only the fields you need. In our sample, Markdown used 66% fewer tokens than pretty JSON.

04

Every SERP feature parsed

Answer box, knowledge graph, People Also Ask, top stories and the local pack come back in the same /v1/search call.

05

Resolved destination URLs

We decode Google's /goto redirects, so each result links to the page itself and carries a canonical domain.

06

Pay for results only

A page of 10 results costs one credit. We refund failed, empty and blocked requests, and each response reports its cost in X-Credits-Used.

07

Batch lane at 50% off

POST /v1/batches queues up to 100 queries per call at 0.5 credits and delivers results to a signed webhook.

08

Official MCP server

Remote MCP at api.serpkite.com/v1/mcp for Claude, Cursor, ChatGPT and any MCP client.

09

Query text stays out of logs

We cache results for a few hours under a hash of the request. Usage logs hold metadata for 31 days, without the query.

Built for AI agents

Search, read and cite in one tool call

Everything an agent's web tool needs is already in the API: page content, ranked passages, cited answers, JSON extraction and research reports written by Claude, a remote MCP server and a fallback when Google blocks.

LLM-native output

Fewer tokens per results page

A full Google SERP as JSON can run to tens of thousands of tokens. Ask for format=markdown or compact, project only the fields you need, and read the X-Tokens-Estimate header before you prompt.

  • 01include_content=3 fetches the top 3 pages as Markdown in the same call
  • 02Resolved URLs no Google /goto redirects, a canonical domain on every result
  • 03SERP features answer box, knowledge graph and People Also Ask in the same credit

Custom Search (CSE-compatible)

For apps moving off the Google Custom Search JSON API: same query params (key, cx, q, start, num…), same items[] and searchInformation shape.

Six engines, one key

Google by default. Five more with one parameter

Add engine to ask Brave, Bing, DuckDuckGo, Yahoo or Yandex instead, fall back automatically with engine=auto, or merge them with engine=consensus. Same request, same JSON, same price.

How multi-engine search works

Official SDKs

Typed clients, three lines to first result

Install serpkite for TypeScript or Python, or the Go module. Every vertical is a method, responses are typed, and retries, timeouts and batch polling are built in. Agent frameworks get native tools: langchain-serpkite and serpkite[crewai].

Google shuts down the Custom Search JSON API in 64 days. Point your client at /customsearch/v1 and keep your code.
// npm install serpkite
import { SerpKite } from "serpkite";

const sk = new SerpKite(); // reads SERPKITE_API_KEY
const res = await sk.search({ q: "best espresso machine", country: "us" });

console.log(res.results[0].title, res.results[0].link);
console.log(res.meta.credits_used, "credit(s) used");
curl https://api.serpkite.com/v1/search \
  -H "Authorization: Bearer $SERPKITE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"q":"best espresso machine 2026","country":"us","language":"en"}'
