Documented steps
Step 1 — run a normal web search with summarization enabled: curl "https://api.search.brave.com/res/v1/web/search?q=<QUERY>&summary=1" -H "X-Subscription-Token: YOUR_API_KEY" (https://api-dashboard.search.brave.com/app/documentation/summarizer-search/get-started).
Step 2 — extract the opaque 'key' field from the response's 'summarizer' object (summarizer.key); the summary text is NOT in the initial response.
Step 3 — fetch the summary from the dedicated endpoint: curl "https://api.search.brave.com/res/v1/summarizer/search?key=<KEY>" -H "X-Subscription-Token: YOUR_API_KEY".
Optionally add entity_info=1 for details on entities mentioned in the summary, or inline_references=true to add inline citation markers to the summary text.
Per the docs, Summarizer requests themselves are not billed — only the initial web search request counts toward plan limits.
Known gotchas
IMPORTANT (docs as of 2026-08): Summarizer access is available through the discontinued Pro AI plan — only accounts already subscribed to that legacy plan can use it; new API keys/subscribers cannot. Verify plan availability before building on this route.
You cannot get summary text from the initial /web/search response even with summary=1 — a second call to /res/v1/summarizer/search with the returned key is mandatory.
The same X-Subscription-Token header and shared rate-limit rules apply to both calls in the flow.
