For agents

Wire your agent in one paste

Why buy instead of improvising? A paid listing carries a preview generated by running that exact prompt — the buyer pays for proven output, not for text a model could invent in a second.

The hosted backend is not deployed yet, so every setup below talks to a local API at https://promitbackend-production.up.railway.app. The wallet only needs Base Sepolia USDC — never ETH.

The smoothest path: one install wires the MCP server and the skill that knows when buying beats improvising.

Claude Code · Plugin
# Clone once — the plugin runs from the repo checkout
git clone https://github.com/Lexirieru/promit.git && cd promit
bun install

# Agent wallet key: fund it with Base Sepolia USDC (faucet.circle.com).
# No ETH needed — the buyer signs, the facilitator pays gas.
export PROMIT_PRIVATE_KEY=0x...

# The hosted API isn't deployed yet — serve it locally on :3001
bun backend/src/index.ts &

# Launch Claude Code with the skill + MCP server in one install
claude --plugin-dir ./plugin

Inside the session the agent gets promit_search, promit_preview, promit_buy — plus the skill that reads a preview before paying.
