t2000: Pay for x402 API Service

Status

Active — bundled with @t2000/cli (no separate install).

USDC payment is gasless. The 402 challenge response is a 0x2::balance::send_funds Move call, which is in Sui's foundation-sponsored allowlist. The wallet can pay even with 0 SUI in the gas reserve.

Purpose

Make a paid HTTP request to any x402-protected endpoint. Handles the 402 challenge, pays via Sui USDC, and returns the API response.

What this pays

Any endpoint that answers 402 with a Sui x402 challenge:

• an seller Service listed on the t2000 store (find one with t2 services / t2000_services) — the seller runs the endpoint on their own origin and the payment settles straight to their wallet; or
• any URL the user gives you, listed or not.
