Brave Search API

Base URL: https://api.search.brave.com/res/v1

Authentication

Every request requires these headers:

X-Subscription-Token: <BRAVE_SEARCH_API_KEY>
Accept: application/json
Accept-Encoding: gzip
Cache-Control: no-cache

Missing Cache-Control: no-cache returns 422. Missing token returns 401.

Read the key from environment: $BRAVE_SEARCH_API_KEY

Basic Web Search

curl -s --compressed \
  "https://api.search.brave.com/res/v1/web/search?q=YOUR+QUERY&count=10" \
  -H "X-Subscription-Token: $BRAVE_SEARCH_API_KEY" \
  -H "Accept: application/json" \
  -H "Accept-Encoding: gzip" \
  -H "Cache-Control: no-cache"

Response fields you'll use most:

• web.results[] — array of results: .title, .url, .description, .extra_snippets[]
• query.more_results_available — boolean, check before fetching next page
• locations.results[] — local business POIs (if query is location-sensitive)
• rich — rich result hint (weather, stocks, etc. if enable_rich_callback=1)

Pagination

Web search: max count=20, offset 0–9 (so max 200 results total).
News search: max count=50, offset 0–9.
Only paginate if query.more_results_available is true.

Freshness Filter

Value	Meaning
pd	Past 24 hours
pw	Past 7 days
pm	Past 31 days
py	Past year
2024-01-01to2024-06-30	Custom date range

Rate Limits and Error Handling

Code	Meaning
200	Success (only successful requests are billed)
401	Invalid or missing API key
422	Validation error — usually missing Cache-Control: no-cache header
429	Rate limit exceeded

On 429, read X-RateLimit-Reset from response headers and apply exponential backoff (1s → 2s → 4s).

Key rate limit headers on every response:

• X-RateLimit-Limit — requests allowed per window
• X-RateLimit-Remaining — requests left this window
• X-RateLimit-Reset — seconds until window resets

Two-Step Workflows

Some endpoints require fetching an ID from web search first:

Summarizer — See references/advanced.md § Summarizer
Local POIs + Descriptions — See references/advanced.md § Local Search
Rich Results — See references/advanced.md § Rich Results

Reference Files

• references/web-search.md — full web search params and response schema
• references/media-search.md — images, videos, news, suggest, spellcheck
• references/advanced.md — summarizer, local POIs, rich results, Goggles

Search Operators (embed in q)

Operator	Example	Effect
Quotes	"exact phrase"	Exact match
Minus	python -snake	Exclude term
site:	site:github.com	Limit to domain
filetype:	filetype:pdf	Specific file type
intitle:	intitle:security	Term in page title

Key Gotchas

• POI IDs from /local/pois expire after ~8 hours — never store them
• Summarizer calls are free — only web search counts toward quota
• Local search requires the "Search plan" (not free tier)
• Image search default safesearch is strict (not moderate like web)
• Image search allows up to 200 results per request (vs 20 for web)
• enable_rich_callback=1 must be explicitly set — rich results are opt-in
