# Web search API, pay per call

Search the web and get the top results as JSON: title, URL, a short snippet and the page age, from the Brave Search API. 1-20 results per call. Results are for the caller's immediate use only: no storing, resale or model training (Brave API terms). Upstream failures and exhausted daily capacity return 503, uncharged. Pair with /extract to read a result in full. Use when an agent needs current information or sources from the open web.

## When an agent wants this

- Give an agent current information or sources from the open web in one call
- Get title, URL, snippet and page age for 1-20 results, then read one in full with /extract
- Ground an answer in live web results without an account or a monthly plan

## Web search results: search the web for a query and get the top pages with title, URL and snippet as JSON

Web search results: search the web for a query and get the top pages with title, URL and snippet as JSON. $0.01 per successful call; failed calls are never charged.

Inputs: q (required): Search query, at most 400 characters; count: Number of results (1-20, default 10).

Not in the free calls (it costs us capacity per call); pay from the first call.

With a card key from https://tools.funwords.eu/credits, in a header or, when your client can only fetch a URL, in the URL:

    curl -H "Authorization: Bearer adt_…" "https://tools.funwords.eu/search?q=x402%20payment%20protocol"
    curl "https://tools.funwords.eu/search?q=x402%20payment%20protocol&api_key=adt_…"

Without a key the same URL answers 402 with x402 and MPP terms, so a wallet client pays USDC per call and retries. Over MCP (https://tools.funwords.eu/mcp) this tool is search.

Example result:

    {
      "query": "x402 payment protocol",
      "provider": "Brave Search",
      "count": 1,
      "results": [
        {
          "title": "x402: an open payment protocol",
          "url": "https://www.x402.org/",
          "snippet": "x402 lets any HTTP API charge per request in stablecoins…",
          "age": "2 days ago"
        }
      ],
      "terms": "Results are for the caller's immediate use: no storing or caching beyond the current task, no resale and no model training (Brave Search API terms)."

## Web answer, AI with citations: answer a question from live search results

Web answer, AI with citations: answer a question from live search results. $0.01 per successful call; failed calls are never charged.

Answer a question from the live web in one call: a Brave web search, the top result pages read, and an answer written by Llama 4 Scout from those sources only, with inline [n] citations and the source list (title, URL). Says so when the sources do not answer it. Results are for the caller's immediate use only: no storing, resale or model training (Brave API terms). Use when an agent needs a current, sourced answer rather than raw search results.

Inputs: q (required): The question, at most 400 characters.
