Overview

AI-generated overview

A remote web search API that lets an assistant run semantic web queries and get back ranked titles, URLs and snippets, paid per call.

What you can do
Run a semantic web search query and receive structured results with titles, URLs and text snippets, ranked by relevance, with up to 10 results per query.
When to use it
Useful when an assistant needs current information beyond its training data: news, documentation, competitor research or general topic lookups. It is a search-only service, not a page-content extractor, SEO auditor or screenshot tool.
Requirements
A remote MCP endpoint reached over SSE; no local runtime, account, API key or signup. Payment is per call in USDC on the Base L2 network via the x402 protocol, so an x402-capable client with a funded wallet is needed to complete the payment challenge.
Before you install
Every search call costs money (listed at $0.008 per query) and is settled in USDC on Base through an x402 payment challenge, so a wallet and signing client are involved. Queries are sent to a third-party search service. The README also points to other paid APIs in the same marketplace, which are separate services.

Installation

In SourceWeft

  1. Open Web Search API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Br0ski777%2Fweb-search/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

Web Search API

[MCP Server] [x402] [License: MIT]

Web search API for AI agents. Structured results with title, URL, snippet. Current news, docs, research. Up to 10 results per query. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

json
{  "mcpServers": {    "web-search": {      "url": "https://web-search.api.klymax402.com/mcp"    }  }}

Quickstart -- HTTP (x402)

bash
curl -X POST "https://web-search.api.klymax402.com/api/search" \  -H "Content-Type: application/json" \  -d '{"query":"..."}'# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
