Payment-gated API for Laso Finance. All paywalled routes use the x402 protocol — the caller includes a USDC payment header on Base (eip155:8453) or Solana (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp) and the server verifies payment before processing. Free routes require no payment header. The same 402 also carries an MPP (Machine Payments Protocol) challenge in WWW-Authenticate; an MPP client pays…

  • laso.finance GET /fund-card-balance — Load a reloadable card balance with USDC. Pay from either chain: the card issuer only accepts USDC on Base, and Laso bridges the payment to the account holder's own deposit address at the issuer over CCTP, which mints native USDC so the full amount arrives. Laso absorbs the bridge cost, so the price is exactly the amount that lands on the balance. Requires a linked card issuer account. Follow with POST /create-reloadable-card to create a card against the balance. (5 USDC on Base)
  • laso.finance GET /get-push-to-card — Send money to a debit card via push-to-card. Supports USD (U.S.), EUR (Eurozone), and GBP (U.K.). Returns a redemption URL to enter card details. (11.5 USDC on Base)
  • laso.finance GET /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. (6.5 USDC on Base)
  • laso.finance GET /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 /withdraw. (11.5 USDC on Solana)
  • laso.finance GET /order-intl-card — Order an international non-reloadable prepaid card (USD). The order is queued and fulfilled by an admin, after which the card details are retrievable via GET /get-card-data with card_type="Non-Reloadable International". A 3.8% fee is added on top of the on-card amount, or less while a fee promotion is running; the 402 challenge carries the exact total. Submit a whole dollar on-card amount. (100 USDC on Base)
  • laso.finance GET /order-gift-card — Order a gift card from the catalog. Browse available cards at GET /search-gift-cards. (5.24 USDC on Solana)
  • laso.finance GET /get-card — Get a prepaid card for use inside the United States (5 USDC on Base)
  • laso.finance GET /auth — Get a Firebase ID token for authenticating with the callable APIs (0.001 USDC on Solana)
  • x402endpoint-utiwoa54hq-uc.a.run.app GET /get-card — Get a prepaid card for use inside the United States (5 USDC on Base)
  • laso.finance GET /get-push-to-card — Send money to a debit card via push-to-card. Supports USD (U.S.), EUR (Eurozone), and GBP (U.K.). Returns a redemption URL to enter card details. (11.5 USDC on Base)
