Fund • Live on Bitcoin mainnet

Fund a session with Bitcoin.

Create a fresh ArkAPI session in the browser, choose 500, 1000, or 1500 sats, and pay through either Lightning or Ark. Live on Bitcoin mainnet — these are real sats.

What this page does

  • Creates a new session: each payment request returns a new bearer token and funding details.
  • Shows both rails: scan the Lightning invoice or the Ark address QR code from the GUI.
  • Polls activation: once payment lands on-chain, the session status flips to active.

Select a funding amount

Choose one of the preset session amounts below. ArkAPI will create a new payment request and show both payment methods immediately. Live on Bitcoin mainnet.

Real Bitcoin. Payments on this page settle on Bitcoin mainnet. ArkAPI is non-custodial and pay-per-call — only failed API calls are auto-refunded to your session balance.

Sessions expire after 24 hours of inactivity. Unused sats are not refundable.
