Learning path

From your first call to an API that agents pay for

10 tutorials in four tracks, in the order we would take them. Each one ends with something running.

About 5 hours end to end for someone comfortable with a terminal. Skip what you already know.

Start with tutorial 1

Track 1

Talk to the chain

Anyone who has used an EVM chain before. No account needed for the first two.

  1. 1
    about 10 min

    Read the chain over public RPC

    You end with: You call the network over HTTPS, hold a subscription open over WebSocket, and watch blocks land several times a second on chain 125.

  2. 2
    about 45 min

    Run a local chain and test Solidity against it

    You end with: A node on your laptop answering on port 8545, a passing Hardhat test, and a Foundry build of the chain contracts.

  3. 3
    about 15 min

    Connect a wallet and send PAX

    You end with: Chain 125 in your wallet, one transaction sent, a signed receipt back in the same call, and the committed block a moment later.

Track 2

Give an agent a wallet

Builders putting an AI agent or a coding assistant in charge of money.

  1. 4
    about 20 min

    Create an agent identity from your wallet

    You end with: An agent identity derived from one wallet signature and tied to your address, so every action the agent takes traces back to you.

  2. 5
    about 60 min

    Run an agent under limits you set

    You end with: An agent running on your machine with a monthly ceiling, an allowlist and an approval step for anything unusual, all enforced before a signature is made.

  3. 6
    about 15 min

    Give your coding assistant a wallet

    You end with: Claude Code, Claude Desktop, Cursor or VS Code can hold PAX, pay for a tool and show you the receipt, and can never exceed the limit you gave it.

Track 3

Pay and get paid

API owners who want agents as paying customers, and agent builders who pay them.

  1. 7
    about 45 min

    Watch four apps pay each other

    You end with: A buyer agent pays a paid API, a shop checks out an order, and a marketplace sells a program, each step verified against a real receipt on the emulator.

  2. 8
    about 30 min

    Put a price on an API route

    You end with: An Express, FastAPI, Spring or Next.js route that answers 402 with a price, releases the result once payment lands, and logs every settlement.

    docs.paxeer.app
  3. 9
    about 20 min

    Prove a payment to someone who was not there

    You end with: A receipt exported as a portable proof that a counterparty, an auditor or a script can verify with no node and no account.

    docs.paxeer.app

Track 4

Build a program

Rust developers who want logic that runs inside the network rather than beside it.

  1. 10
    about 30 min

    Scaffold, test and deploy a program

    You end with: A new program project from one command, built and tested in the workspace, tried in a sandbox, and deployed with a metered fee.
