These docs mostly cover the seller journey — putting a paywall in front of your API. This section covers the buyer journey: you already have a Proceeds payment URL, and you want an AI agent to pay it for you. Agents pay Proceeds endpoints the same way any client does — request, get a 402 challenge, sign a payment, retry. The difference is the wallet and tooling live inside your agent. Pick a tool below, install it in your IDE, fund a wallet, then hand your agent a Proceeds URL.

​
Give your agent these docs

Before wiring up a wallet, let your agent read the documentation directly: MCP server — search and read tools for these docs:
llms.txt — full docs index for LLMs: docs.myproceeds.xyz/llms.txt

​
Before you start

You need:
  • A Proceeds payment URL for the endpoint you want to call:
Every paywall uses that one URL. The 402 challenge offers MPP only when Tempo is a supported network, and x402 when an EVM network such as Base is enabled.

​
Pick your tool

All three tools work from Claude Code, Cursor, and Codex. Choose based on the standard your target paywall accepts and the wallet experience you want.

​
Use from your IDE

The setup pattern is the same across Claude Code, Cursor, and Codex:
1

Install the CLI or skill

Each tool ships a CLI, an agent skill, or an MCP server. Install it once in the IDE where your agent runs (see the per-tool pages for the exact command).
2

Fund a wallet

Onboard and fund an agent wallet with USDC.
3

Hand the agent a Proceeds URL

Give your agent the paywall URL and ask it to call the endpoint. The agent handles the 402 challenge, signs the payment, and retries automatically.
4

Confirm in the dashboard

Watch the matching record land as Completed in Transactions (nanopayments go Pending → Completed after Gateway batch settlement), and trace each step in Events.

​
Proceeds URL cheat sheet

x402, MPP, and Circle Nanopayments share one charge URL. The challenge advertises which rails the paywall accepts.
