Frequently asked questions
-
What is the Olostep Answers endpoint?
The Olostep Answers endpoint lets you ask any natural language question about the web and receive AI-powered, structured JSON back. It searches live sources, reads relevant pages, cross-validates results, and returns NOT_FOUND when data cannot be verified — never a hallucinated guess.
-
How is this different from a regular LLM or ChatGPT?
Unlike LLMs that rely on static training data, the Answers endpoint searches the live web on every call powered by the Olostep scraping and crawling API. You get real-time, source-backed answers grounded in actual web pages — not knowledge that may be months or years out of date.
-
What does NOT_FOUND mean?
When the endpoint cannot verify a data point from live web sources, it returns NOT_FOUND for that specific field rather than guessing. This gives you full confidence in what was actually found versus what is unknown.
-
Can I define the JSON shape I want back?
Yes. Pass a json parameter with an object describing the fields you want. For example: {"funding_stage": "", "investors": []}. The API will map every found fact into your schema automatically.
-
Are sources always included in the response?
Yes. Every answer includes the URLs that were read to generate it. You get full traceability — no black-box outputs. You can verify every claim against the original source.

-
Can I use it for bulk enrichment?
Yes. Feed in a list of companies, people, or URLs and get back a fully enriched dataset in structured JSON. This is ideal for CRM enrichment, lead intelligence, and research automation workflows.
-
Does it work with any LLM or AI pipeline?
Yes. The endpoint is designed as a drop-in tool for any LLM pipeline. Use it to ground your AI assistant with real-world data, prevent hallucinations, or enrich context before passing it to your model.

How much does the Answers endpoint cost?
Answers costs 20 credits per request. The first 500 credits are free — no credit card required. Paid plans start from $9/month.
