x402-proxy
CLI and MCP proxy that auto-pays x402/MPP-gated endpoints on Base, Solana, Monad, and Tempo from one mnemonic.
Last release Aug 14, 2026 · Last commit Aug 14, 2026 · ★ 11
Overview
x402-proxy is described by its own README as "curl for x402 and MPP paid APIs" — a CLI and MCP proxy that derives EVM and Solana keypairs from a single BIP-39 mnemonic and handles both one-time and streaming payments automatically. An agent builder drops it in front of any x402-gated endpoint to remove the need to write payment-signing code per chain.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 44 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Rates spanning that date mix two definitions. Since then: 100%.
