}JavaScript — @x402/fetch
Client ufficiale x402 v2. Installa @x402/fetch e @x402/evm. Il vecchio nome di pacchetto x402-fetch è la linea v1 deprecata e non va usato per questi endpoint.

stdio copre l’intero catalogo (entrambi gli host API). Clona forge-agent-mcp e punta il client MCP a src/server.mjs. Il remote Streamable HTTP ospitato sul gateway originale espone ancora solo i tool di quel gateway.
