Frequently Asked Questions about Serpex

Does Serpex return Google results, or does it use alternative search engines?

Serpex pulls from multiple engines including Google and Bing, with auto-routing that selects the best source for your query. You can also specify which engine you prefer, so you are not locked into one source for all requests.

What format does Serpex return search results in?

Results come back as structured JSON through the API, ready to feed directly into LLM applications or RAG systems. Serpex also converts web pages to markdown automatically, which skips the cleanup work if you are ingesting content for AI training.

How many requests can I make on the free trial?

The free trial gives you 200 credits to test the API. Since each search or extract request costs one credit, you get 200 requests before you need to pay.

Will Serpex block or slow down my requests if I hit rate limits?

Serpex includes rate limiting protection built in, and the Scale plan ($500/month) supports up to 100 concurrent requests. For volumes beyond that or custom concurrency needs, contact their sales team about the Enterprise tier.
