    This is an MCP stdio server, not a conventional client SDK - it wraps 14 of the 18 services as MCP tools
    and auto-pays each call from a Base wallet key supplied in ANCHOR_WALLET_PRIVATE_KEY. Current as of this
    pass: the latest release is one week old and the API it wraps last shipped 2026-09-09, so there is no
    abandonment signal here.

    Coinbase's generic x402 v2 client, recommended in llms.txt as the plain-HTTP path. Not first-party to
    anchor-x402; version deliberately not recorded here because it is another vendor's release cadence.

    llms.txt names "the Python x402 SDK" without linking a package, so no registry coordinate could be
    confirmed. Recorded as an honest gap rather than guessed.
finding: >-
  There is no first-party client SDK in any language. The provider's position is that none is needed - the
  wire protocol is an ordinary HTTP 402 challenge that any x402 v2 client already speaks - so the one
  package it does ship is an MCP server rather than an SDK. That is a defensible design choice, but a
  consumer who is not already running an x402 client has no vendor-maintained library to reach for.
