Retrieve the current USDC wallet balance for the Agent's Smart Contract Wallet.

Send a standard Modexia payment (USDC) to a recipient. Recommended to always provide an idempotency_key to prevent double charges. Optionally provide a memo to explain the reason for the payment (visible in audit trail).

Send a cross-chain CCTP payment natively to another blockchain using Squid Router. Requires to_chain (e.g., '1' for Ethereum, 'akashnet-2' for Akash Network), to_token address, and the recipient wallet address. Gas relaying on the destination is covered automatically! Always provide an idempotency_key to prevent double charges.

Fetch the recent transaction history for the authenticated agent.

Open a high-frequency micro-payment vault channel with on-chain deposit. Blocks funds for the specific provider, allowing instant, gas-free payments via consume_channel.

Execute an instant, gas-free micro-payment inside an already open channel. Call this as many times as needed while the channel is open.

Settle an open micro-payment channel, paying the provider, and refunding the remainder back to you.

Get the current status, deposit amount, and remaining balance of a specific payment channel.

List all payment channels associated with the authenticated agent's wallet.

Fetch an external resource via HTTP. If the resource responds with a 402 Payment Required and a WWW-Authenticate header, this tool will automatically negotiate and pay the invoice via Modexia AgentPay, then retry the request with the cryptographic proof of payment.

Submit an intent-based payment (v2 API). Creates a signed intent token, submits it through the validation pipeline, and returns a rich result with compliance metadata (policy limits, daily spend, balance). Always provide a memo describing why you are making this payment.

Get the status and details of a previously submitted payment intent.

List the most recent payment intents with their status and details.

Fetch an x402-protected resource and automatically pay using Circle Gateway nanopayments. Gas-free, instant, supports payments as low as $0.000001 USDC. Use this for sub-cent API calls and premium data purchases.

Get the agent's Circle Gateway nanopayment balance (separate from main wallet balance).

Deposit USDC from the agent's main wallet into the nanopayment Gateway. This is an on-chain transaction. After depositing, nanopayments are gas-free.

Withdraw USDC from the nanopayment Gateway back to the agent's main wallet.

Enable Circle Gateway nanopayments for this agent. Must be called once before using nanopay, nanopay_deposit, or nanopay_balance. Idempotent — calling again returns the existing activation.
