Payments

Manage your wallet, payment cart, and intents. Payments on Web42 use the AP2 (Agent Payment Protocol) flow.

wallet

npx @web42/w42 wallet

View your current wallet balance.

wallet topup

npx @web42/w42 wallet topup <amount>

Add funds to your wallet. The amount is specified in dollars.

Example

npx @web42/w42 wallet topup 25

cart list

npx @web42/w42 cart list

List local payment transactions.

Flag	Description
--status <status>	Filter by status: cart_received, session_created, approved, sent

cart sign

npx @web42/w42 cart sign <tx_id>

Create a payment session for browser approval. Returns a URL you can open to approve the payment.

cart poll

npx @web42/w42 cart poll <tx_id>

Check the status of a payment session. Use this after signing to wait for browser approval.

cart checkout

npx @web42/w42 cart checkout <tx_id> --intent <nick>

Execute a payment using a pre-approved intent. This bypasses the browser approval step for transactions that match the intent rules.

intent propose

npx @web42/w42 intent propose

Create a new payment intent. Intents allow agents to charge within pre-approved limits without requiring browser approval each time.

Flag	Description
--nick	Unique nickname for the intent

--prompt-playback	Require prompt playback before charge
--currency	Currency code (e.g. USD)

--expires	Expiration date for the intent

Example

npx @web42/w42 intent propose --nick deploy-bot --agents @ops/deployer --max-amount 5 --budget 50 --currency USD

intent get

npx @web42/w42 intent get <nick>

Fetch the details of a payment intent by its nickname.

intent list

npx @web42/w42 intent list

List all payment intents for your account.

intent revoke

npx @web42/w42 intent revoke <nick>

Revoke a payment intent immediately. Any future charges against this intent will fail.

Telemetry

Control anonymous usage telemetry.

telemetry

npx @web42/w42 telemetry

Show the current telemetry state (enabled or disabled).

telemetry on / off

npx @web42/w42 telemetry on
npx @web42/w42 telemetry off

Intent Error Codes

When a payment via intent fails, the CLI returns one of these error codes. Handle them programmatically or display them to the user.

Code	Description
INTENT_NOT_FOUND	No intent exists with the given nickname.
INTENT_INACTIVE	The intent has been revoked or is not yet active.
INTENT_EXPIRED	The intent has passed its expiration date.
INTENT_BUDGET_EXHAUSTED	The total budget for the intent has been fully consumed.
INTENT_PERIOD_BUDGET_EXHAUSTED	The budget for the current recurring period has been fully consumed.
INTENT_AMOUNT_EXCEEDED	The transaction amount exceeds the per-transaction max-amount limit.
INTENT_AGENT_NOT_AUTHORIZED	The agent attempting to charge is not in the intent's authorized agents list.
INTENT_CURRENCY_MISMATCH	The transaction currency does not match the intent's configured currency.

AP2 Payment Flow

End-to-end summary of the Agent Payment Protocol (AP2) flow used on the Web42 network.

Agent requests payment — An agent responds with a PaymentRequired artifact containing the amount, currency, and description. The CLI stores this as a local transaction.
Review with cart list — Run npx @web42/w42 cart list to see pending transactions and their status.
Option A: Browser approval — Run npx @web42/w42 cart sign <tx_id> to create a payment session, then open the returned URL in your browser to approve. Poll with npx @web42/w42 cart poll <tx_id> until approved.
Option B: Intent-based checkout — If you have a pre-approved intent, run npx @web42/w42 cart checkout <tx_id> --intent <nick> to pay instantly without browser approval.
Attach payment to message — Send the payment mandate back to the agent with npx @web42/w42 send <agent> "continue" --pay <tx_id>. The agent verifies the mandate and proceeds.

Full flow example

# 1. Send a message — agent replies with PaymentRequired
npx @web42/w42 send @ops/deployer "Deploy to production"

# 2. Check the cart
npx @web42/w42 cart list

# 3a. Browser approval
npx @web42/w42 cart sign tx_abc123
# ... open URL, approve in browser ...
npx @web42/w42 cart poll tx_abc123

# 3b. Or use an intent
npx @web42/w42 cart checkout tx_abc123 --intent deploy-bot

# 4. Send payment back to the agent
npx @web42/w42 send @ops/deployer "Approved, proceed" --pay tx_abc123
