How are credits charged for failed requests?

Failed requests should not deduct any credits from your account. If you notice any incorrect credit deductions, please contact us at sys@search1api.com for assistance.

How does DeepSearch mode billing work?

In DeepSearch mode, credits are charged based on the search query (1 credit) plus the number of successfully crawled pages. For example, if you set crawl_results=4 but only 3 pages are successfully crawled, you will be charged 1+3=4 credits instead of 1+4=5 credits.

What is your refund policy?

Purchases are non-refundable. You can cancel a subscription at any time from your dashboard — cancelling stops the next billing cycle, but the current period is not refunded. If the service doesn't match what this site describes, email us at sys@search1api.com and we'll issue a refund once we've confirmed it.

S1 Q&A

Search results are typically delivered within 1-2 seconds. For most queries, you'll get instant responses that you can use in your applications.

The Search endpoint supports 17 engines: Google, Bing, DuckDuckGo, and Yahoo for general web; GitHub, arXiv, Reddit, and X for developer and community sources; YouTube, Wikipedia, and IMDb for media and reference; and WeChat, Bilibili, Baidu, 360, and Quark for the Chinese-language web. Set search_service in the request to pick one.

Website crawling is a complex process, and we cannot guarantee that all websites can be crawled at all times. However, we have adapted to crawl popular websites, including YouTube, Reddits, GitHub, Medium, and WeChat Official Accounts. If you are a corporate user, we can provide customized services to optimize crawling for your frequently used websites, while improving the success rate and presentation of crawled content.

Search1API gives AI agents one web access layer for search, crawl, extract, sitemap, and trending workflows. You can integrate it directly over HTTP or connect through MCP, CLI tooling, and reusable skills in agent environments such as Claude, Cursor, Windsurf, and custom apps.
