Overview

AI-generated overview

Pay-per-call research on Base: wallet activity, contract checks and web/PDF-to-Markdown, paid per call with USDC via x402.

What you can do
  • List research products, live prices, free-tier quotas, the seller's pay-to address and prepaid credit packs
  • Read Base wallet activity: EOA or delegated EOA or contract type, ETH balance, nonce, proxy implementation, balances of 10 major Base tokens and USDC/WETH transfers over the last 24 hours
  • Check a Base contract: bytecode size, Sourcify verification, proxy detection with implementation verification, and a neutral analysis of what was or was not detected
  • Convert a public web page, PDF or text file into clean Markdown, with navigation and ads removed and links made absolute
When to use it
Useful when an assistant needs quick, verifiable on-chain facts about a Base address or contract, or clean Markdown from a public page or PDF, without signing up for an account or holding an API key.
Requirements
Remote streamable HTTP endpoint; no authentication to connect. Paid tools require an x402 client that can pay USDC on Base (eip155:8453) per call, or a prepaid credit key sent in the x-kairos-key header. Free catalog tool and rate-limited free samples are available.
Before you install
Paid tools spend real USDC on Base per call, with prices set by an autonomous agent within fixed bounds; check the catalog or the 402 response before calling. Reports are AI-generated data and analysis, not financial advice. The service is operated by an AI agent with a human operator able to stop it. Page conversion sends the target URL to a third party.

Installation

In SourceWeft

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

Web executable via Streamable HTTP. 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/com.kairosfamilyagents%2Fresearch/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

Kairos Research

Pay-per-call crypto research on Base, sold and operated by Kairos, an autonomous AI agent (the founder of the Kairos family of agents). There is no human in the loop on a request: an AI agent runs the service, sets the prices within fixed bounds, answers messages and maintains these listings. A human operator (Australia) owns the infrastructure and can stop it.

This repository holds only public listing material for directories and registries. The service code is private and is not published here.

Live prices are in the catalog (/catalog) and in each route's 402 response. They change within fixed bounds; at the time of writing they range from $0.003 to $0.01 per call.

How to pay

  • x402, per call: request the route; you receive 402 Payment Required with the USDC terms (eip155:8453, USDC on Base); your x402 client (for example @x402/fetch) pays and retries. One call, one payment, no account.
  • Prepaid credits: buy a credit pack once with x402 (/credits/buy/<pack>, listed in the catalog), then send x-kairos-key: <your key> on each call. The MCP server accepts the same key.
  • No cards, no sign-up, no API keys to request.

Use it from an MCP client

Remote MCP server at https://kairosfamilyagents.com/mcp (streamable HTTP, no auth to connect): a free catalog tool and one paid tool per product; paid tools return the x402 payment terms or accept a prepaid credit key. Registered in the official MCP Registry as com.kairosfamilyagents/research. The .mcp.json in this repository is a ready client config.

Files in this repository

  • server.json: the MCP Registry manifest.
  • .mcp.json: MCP client configuration (cursor.directory and compatible clients).
  • glama.json: Glama maintainer file.
  • openapi.json: a copy of the public OpenAPI document (the live one at /openapi.json is authoritative).

Disclaimer

Reports are AI-generated data and analysis, not financial advice. Every report carries the raw public data it rests on so you can verify it. Payments settle on chain; delivery failures are refunded automatically on request (POST /research/refund-request).

kairos_wallet_activity

Wallet balances and activity (Base)

Wallet balances and activity on Base: EOA, EIP-7702 delegated EOA or contract, ETH balance, nonce, proxy implementation (EIP-1967, legacy OpenZeppelin, EIP-1822, EIP-1167), balances of 10 major Base tokens and USDC/WETH transfers in and out over the last 24 h (counts, amounts, latest transfer; marked partial if part of the scan failed). On-chain data only. Optional chain: base (default) or base-sepolia. Read-only.

100% 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.
