Is this the Brave Search API?

No. Brave's own API sells search results and a separate answers product; this endpoint returns the AI answer search.brave.com shows a visitor, with its sources, fan-out queries and products. For Brave web results, use engine=brave on /v1/search.

How much does it cost?

2 credits per answer, $2.00 → $1.20 per 1,000 answers depending on the pack. Failed and empty answers are free.

Do you log in to the assistant?

No. Every prompt is asked the way a logged-out visitor asks it, in a standard browser, and we never use accounts or anything behind a login. Assistants that ask every logged-out visitor to sign in are not offered.

Why does the answer change between runs?

Assistants don't give the same answer twice: wording, sources and products vary from run to run and by country. For tracking, ask each prompt several times (a batch or a monitor) and count how often you're named or cited, rather than reading one answer.

How do I track my brand in the answer?

Pass track with up to 20 brands and domains. Each comes back in mentions: whether the text names it, whether a cited source is on it, which sources and products match, and how early the text first names it (text_position, 0 to 1).

Can I run hundreds of prompts?

Yes. Send up to 100 prompts per call to POST /v1/batches with endpoint: "brave_ai" and collect the answers from a signed webhook. AI answers cost the same in the batch lane (no 0.5× discount), because each one holds a browser for 1–10 s.

Overview

What the Brave AI Answers API does

POST /v1/brave_ai asks Brave Search's AI answer as a logged-out visitor and returns the answer as text and markdown with [n](link) citations, the inline-cited sources, the search_queries it ran to answer (its fan-out), and products with price, rating and merchant.

It is the fastest of the assistants, 1 to 10 seconds per answer, and the cheapest, which makes it a good first pass over a large prompt set. country sets Brave's market (prices and shops follow it).

track adds mentions for up to 20 brands and domains.

What you get

sources[] array: position (the n in the citations), title, link, domain, snippet, date, cited (true: cited inline in the answer; false: only listed beside it).
search_queries[] array: The searches the assistant ran to answer (its fan-out), where it shows them.

places[] array: Local businesses the answer showed, same shape as /v1/maps results.
related_questions[] array: Follow-up questions the assistant suggested.

See AI visibility tracking.
