Question 1

What is Sift?

Accepted Answer

Sift is a REST API that, in a single call, searches the live web, concurrently crawls the top results, strips boilerplate to clean Markdown, filters SEO spam, and re-ranks the resulting text chunks with a cross-encoder so you get clean, relevant context for retrieval-augmented generation.

Question 2

How does pricing work?

Accepted Answer

Pay-as-you-go from a prepaid credit balance. Each search costs $0.005 base, plus $0.001 per additional page crawled, plus $0.002 when cross-encoder re-ranking runs. Spam filtering is free. Top up credits via Stripe.

Question 3

How do I authenticate?

Accepted Answer

Sign in with Google or GitHub to the dashboard, generate an API key, and pass it as an 'Authorization: Bearer <key>' header on requests to POST /v1/search-rag.
