Search1API puts 17 search engines, crawling and DeepSearch behind one API. The AppSumo deal is $49, but it's a one-time credit pool, not unlimited use.

Lifetime Deal

See deal on AppSumo

Our take: Worth a look if you build AI agents or n8n workflows and want one web access layer instead of several API accounts. Skip it if you need heavy, ongoing volume, guaranteed crawling of every site, or a mature product with a long track record. The credits are a finite pool, and the listing is unclear about how they map to tiers.

What we like

  • 17 search engines behind one endpoint, including six Chinese platforms
  • Works over plain HTTP or through MCP in Claude and Cursor, and it lists n8n as an integration
  • Failed requests aren't supposed to cost credits
  • Entry price of $49 is low for a developer utility

Watch out for

  • Credits are one-time, so a lifetime deal is really a prepaid balance
  • The listing's credit numbers are out of order and not clearly tied to tiers
  • Crawling can fail on some sites and only a handful are specifically supported
  • Only one AppSumo review so far, and no demo video

You’ve built an AI agent that needs to look things up. Then the plumbing starts. One service for web search, another to pull the text off a page, a third thing for YouTube, and a pile of API keys to keep track of. Each one has its own pricing and its own way of breaking.

Search1API product screen

Search1API is a bet that you’d rather have one door. According to the listing, it gives AI agents a single web access layer for search, crawl, extract, sitemap and trending workflows. You can call it over HTTP, or connect through MCP, CLI tooling and reusable skills in Claude, Cursor, Windsurf and custom apps. The AppSumo page also lists n8n and Codex as integrations.

That’s the pitch. Here’s what’s actually on the page, and what isn’t.

The pitch: one endpoint, many sources

The headline feature is a single search endpoint that fronts 17 engines. You pick one by setting a search_service parameter. The listing groups them like this:

  • General web: Google, Bing, DuckDuckGo and Yahoo
  • Developer and community: GitHub, arXiv, Reddit and X
  • Media and reference: YouTube, Wikipedia and IMDb
  • Chinese-language web: WeChat, Bilibili, Baidu, 360 and Quark

That’s a sensible spread. Most search APIs give you one general engine and call it a day. Having GitHub, arXiv and Reddit as first-class sources is useful if you’re building a research or developer-facing agent.

The Chinese platforms are the unusual part. If your customers or your content touch that market, they matter a lot. If they don’t, you’re paying for coverage you’ll never call.

Crawling, and where it gets honest

The second feature is page crawling. The listing says you get clean results from a page in about 3 seconds, with anti-crawling handling for popular sites like YouTube and Reddit. Search results, separately, are described as typically arriving in 1-2 seconds.

Those are the vendor’s numbers. We haven’t run anything, and there’s no demo video with this listing, so treat the speeds as claims.

The FAQ is more candid than the feature blurb. It says crawling is complex and not every site can be crawled every time. The sites it names as adapted are YouTube, Reddit, GitHub, Medium and WeChat Official Accounts. Corporate users can get customized crawling for sites they hit often.

Read that plainly. If your agent needs to read arbitrary pages across the open web, expect some misses. If it mostly reads from the named sites, you’re in better shape.

Search1API features at a glance

How the credits work

Plain search billing isn’t spelled out. DeepSearch is. In that mode you pay 1 credit for the query plus 1 credit per page crawled successfully. Ask for four pages and get three, and you’re charged four credits in total.

That’s fair. The listing also says failed requests shouldn’t deduct credits, and points you to sys@search1api.com if they do. Good policy, though it’s worth checking your balance against your own request logs early on.

There’s a privacy note too. The listing says Search1API doesn’t store search results and processes each request in real time.

The deal, and the number that doesn’t add up

The lifetime deal runs on four tiers: $49 (list $80), $98 (list $160), $147 (list $240) and $196 (list $320). You can stack up to four codes. You have to redeem within 60 days of purchase, and the listing promises all future plan updates.

The credits line is where the listing gets muddled. It reads 240,000 / 80,000 / 320,000 / 160,000, in that scrambled order. Those four numbers would fit four steps of 80,000 credits, one per tier, which would put the $49 tier at 80,000. But the page doesn’t label them against tiers, so don’t assume. Confirm what your tier gets before you pay.

The bigger point is the word one-time. These credits don’t refresh monthly. A lifetime deal usually means ongoing access, and here the thing you’re buying is a fixed balance. The listing doesn’t say what happens when it runs out, whether there’s a way to top up, or what the regular price per credit is. Without that, you can’t tell whether $49 is a bargain or just a prepayment.

The refund wording is also odd. The FAQ says purchases are non-refundable and talks about cancelling a subscription, which reads like text from a subscription plan. It then says you can email for a refund if the service doesn’t match its description. Check AppSumo’s own refund terms before relying on any of it.

Who should skip it

Skip it if you want something you can leave running for years at steady volume. A finite credit pool and an unstated top-up price make long-term budgeting a guess.

Skip it if you aren’t technical. This is an API, and every integration listed (n8n, Claude, Cursor, Codex) is developer or automation territory. Nobody on your team is going to open a dashboard and just search.

Be cautious, too, if you need dependable scraping of obscure sites. The vendor itself says some crawls fail.

And keep the maturity question in mind. The listing shows one AppSumo review, a 5.00 average, which tells us very little. It’s a young product with a thin public record.

Search1API price and limits

It makes sense for a freelancer, a small agency or a developer who’s already wiring up agents and wants to stop juggling search accounts. At $49 the downside is small, as long as you treat it as a prepaid balance and run a small real workload within the 60-day redemption window.

Frequently asked questions

Are the credits in the Search1API lifetime deal renewable?

No. The listing calls them one-time API credits, so once you use them up, the listing doesn't say what happens next. Treat the deal as a prepaid balance, not unlimited access.

How are credits charged in DeepSearch mode?

According to the listing, you pay 1 credit for the search query plus 1 credit for each page that crawls successfully. If you ask for 4 pages and 3 succeed, you're charged 4 credits.

Can Search1API crawl any website?

No. The listing says not every site can be crawled every time. It names YouTube, Reddit, GitHub, Medium and WeChat Official Accounts as sites it has been adapted for, and offers customized crawling to corporate users.
