# Web search API, pay per call

Exa-style web search: top 1-20 results with title, URL, snippet, published date and favicon (Brave index); optional domain, date, category and phrase filters; optional live page text, highlights and AI summaries of the top 10 pages. Results are for immediate use only: no storing, resale or model training (Brave API terms). Failures return 503, uncharged. 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

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

    curl -H "Authorization: Bearer adt_…" "https://glyphcall.com/search?q=x402%20payment%20protocol"
    curl "https://glyphcall.com/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://glyphcall.com/mcp) this tool is search.

## 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.
