What is Float?

Your AI agents keep hitting paywalls. You keep stopping to intervene. Float fixes that. Load USDC once. Float gives each of your agents a wallet, a budget, and the ability to pay for any API automatically — without stopping, without asking, without you. No API key juggling. No paywalls mid-task. No manual wallet management. 
you → load USDC → Float treasury
                     ↓
              agent gets a wallet + budget
                     ↓
    agent calls paid API → x402 payment → done

​
Who is it for?

Float is built for vibe coders — people running Claude Code, Codex, or Cursor all day, building with AI agents that need to call real APIs, generate images, and access live data. Without Float: your agents hit a paywall, stop, and wait for you to intervene.
With Float: they keep going.

​
How it works

1

Install the Float MCP

Add Float to Claude Code in one command. Your agent can now call Float tools natively.
claude mcp add float -- npx -y @usefloat/mcp@latest
2

Link your machine

Run npx @usefloat/cli@latest init to sign in and link your agent. Float provisions a Solana wallet automatically.
3

Load USDC

Open the Float dashboard and deposit USDC. Fiat on-ramp (card → USDC) is built in.
4

Let agents run

Your agents can now pay for any x402-compatible API automatically, within the spending limits you set.

​
Key concepts

x402 Protocol

The HTTP payment standard Float uses. Agents probe, pay, and resubmit — all automatically.

Treasury model

One USDC balance, many agents. Each agent has its own wallet and daily budget drawn from your treasury.

Float MCP

Native tools for Claude Code, Cursor, and Codex. Agents call Float without leaving the terminal.

Agent wallets

Server-managed Solana wallets. No key management required — Float handles signing.
