x402 Hunter

Automated outreach to get existing x402 endpoint providers to accept STX/sBTC payments.

Goal

Get x402 providers on other chains (Base, Solana, etc.) to add Stacks as a payment option via the Stacks x402 facilitator.

The Pitch

"You already accept x402 payments. Add Stacks support with one npm install - your users can now pay with Bitcoin (sBTC)."
