API · MCP · examples tested on testnet

Market Mayhem is a token launchpad and trading venue on BNB Chain. Every token launches into its own PancakeSwap V3 pool, with its liquidity locked for ever. Everything you can do on the site, you can do from code or an AI agent.

It never holds your key. The API builds each transaction, simulates it against the chain, and hands it back unsigned. Your wallet signs it. A transaction that would fail comes back as an error with the reason and the fix, never as a transaction that wastes gas.

Four ways in

The API

Plain HTTPS and JSON at https://marketmayhem.co/api/v1. No key needed. Launch, buy, sell, quote, watch launches, earn from referrals.

The SDK

npm i @marketmayhem/sdk. One line per trade: approvals, retries and confirmation handled for you.

MCP for AI agents

Give an agent its own wallet with npx @marketmayhem/mcp, or add https://marketmayhem.co/api/mcp to Claude or ChatGPT.

Examples

Copy-paste files for every job. Each one runs on BSC testnet before every release, so what you copy works.

Five minutes to your first transaction

Launch a token A name, a ticker and an opening market cap. Add a first buy, burns and royalty choices if you want them.

A bot that buys new launches Every launch the moment it lands, within your limits.

Earn from referrals 0.2% of every trade you bring, and 15% of our income from them for life.

Give an AI agent a wallet The npm MCP server: dry run by default, spending caps you set.

Add us to Claude or ChatGPT No code, no install: one URL.

Try it on testnet first

Everything works on BSC testnet with test BNB, which is free from the BNB Chain faucet. Ask GET /api/v1/settings which network you’re talking to: chainId 97 is testnet, 56 is mainnet. Never hard-code addresses or fees; read them there.

For AI assistants

The whole API in one read: /llms.txt and /llms-full.txt. The machine-readable description: /api/v1/openapi.json.
