Offers

Offer	Endpoint	Price
Auth Get a Firebase ID token for authenticating with the callable APIs	`/m/bz-laso-finance/auth`	0.001 USDC
Get Card Get a prepaid card for use inside the United States	`/m/bz-laso-finance/get-card`	5 USDC
Order Gift Card Order a gift card from the catalog. Browse available cards at GET /search-gift-cards.	`/m/bz-laso-finance/order-gift-card`	5.24 USDC
Send Bank Payment Send dollars to a bank account by ACH. Requires a bank destination registered beforehand with addBankingDestination (list them at GET /bank-recipients), which in turn requires an approved banking profile. The on-chain x402 payment credits the user's account balance via the standard deposit webhook, so a payout that cannot be fulfilled leaves nothing stranded — retry, or recover the funds with POST	`/m/bz-laso-finance/send-bank-payment`	11.5 USDC
Send Payment Send a payment via Venmo or PayPal. Requires KYC verification on the calling wallet; if not yet verified the response returns a kyc_url instead of sending the payout. The on-chain x402 payment credits the user's account balance via the standard deposit webhook, so abandoned/unverified flows can be recovered with POST /withdraw.	`/m/bz-laso-finance/send-payment`	6.5 USDC

Pay with an agent

Any MPP or x402-compatible client works. With mppx, payment is automatic:

import { Mppx, evm } from 'mppx/client'
import { privateKeyToAccount } from 'viem/accounts'

const mppx = Mppx.create({
  methods: [evm({
    account: privateKeyToAccount(process.env.KEY),
    currencies: [evm.assets.base.USDC],
  })],
})

const res = await mppx.fetch('https://api.meshgateway.co/m/bz-laso-finance/auth')
// 402 challenge signed and settled automatically; response includes Payment-Receipt

Or inspect the challenge yourself:

curl -i https://api.meshgateway.co/m/bz-laso-finance/auth
