Web search API for AI agents: top results as JSON, pay per query

$0.01 per call · failed calls are never charged · no account or API key needed

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 to use it

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

Buy credits by card (from $5) Example result (JSON)

Inputs

Name	Type	Description
`q` (required)	string	Search query, at most 400 characters
`count`	integer	Number of results (1-20, default 10)

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/search?q=x402%20payment%20protocol"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum, Monad, World Chain or Tempo) and retries.

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)."
}

From an AI agent (MCP)

Add the MCP server to Claude, Cursor or any MCP client. This tool is search, and the first 25 successful calls are free:

Questions

Where do the results come from?

The Brave Search API, one request per paid call. Results are for the caller's immediate use: no storing, resale or model training.

What if the search provider is down or the daily capacity is used up?

The call answers 503 and nothing is charged.

How do I pay?

Each successful call costs $0.01; failed calls are not charged. This tool is not in the free calls; pay with card credits (from $5) or per call in USDC over x402 or MPP. No account or API key is needed.
