Crypto payment links in your own currency

A send21 pay link asks for a fixed amount in your currency and lets the payer choose how to pay. The rate locks when they choose, so your price holds, and the payment goes straight to your wallet.

What the payer sees

  • Your amount in your currency, your message, and the currencies you accept.
  • After picking one: one QR code, the exact amount, and how long the rate is locked.
  • Payment from any wallet: BIP-21 for bitcoin, a Lightning invoice, Solana Pay, or EIP-681 for EVM chains.
  • A notice not to pay again if a payment with a different amount already arrived.

What you get

  • Payment straight to your own addresses, one per network you accept.
  • An email and a signed webhook when the payment is seen and confirmed, with your order id.
  • A list of your requests with their status, and drafts with PDFs for your records.

Make one

In the app, open Get paid. From code, one call to POST /api/v1/payment-requests (see the quickstart). AI agents can do the same through the MCP server.
