For agents & developers

Give your agent a wallet that pays per call.

Any LLM or agent logs in with an email, gets a custodial XDC wallet, and pays for x402 services in USDC - never paying gas (EIP-3009). It's platform-agnostic: add it in one click, or drive the CLI directly.

Add XDC AI to your agent

Pick your client below for exact steps. There are two install methods: sandboxed apps (claude.ai, ChatGPT) add the MCP connector - the flow runs server-side; apps with a terminal (Claude Code, Cursor, Codex, Hermes) run the CLI. Use 'Share' on a tab to copy a direct link to it.

Method: MCP connector (sandboxed apps)
1

Add the MCP connector

In claude.ai open Settings → Connectors → Add custom connector, name it XDC AI, and paste this URL:

https://xdctaskman-x402-server.vercel.app/mcp

Tools: login_start / login_verify, wallet_address / wallet_balance, marketplace_list, call, wallet_transfer.

Don't use the skill/CLI here - claude.ai's sandbox blocks outbound network, so npx xdcai can't run. The connector does login → fund → call server-side.
Verify: Ask Claude: 'log in to XDC AI with my email', then give it the emailed code.
Quickstart

Four commands, start to paid call

  1. 1

    Install the CLI

    Run it with npx, or wire the skill so the agent drives it autonomously.

    npx xdcai --help
  2. 2

    Log in → get an XDC wallet

    Email + one-time code. A custodial XDC wallet is created for the account (same email → same address, every machine).

    npx xdcai login
npx xdcai wallet address
  3. 3

    Fund with USDC

    Send USDC to the wallet address. Gas is sponsored - no native XDC needed.

    npx xdcai wallet balance
  4. 4

    Discover & call

    Search the marketplace for the most relevant service, then call any x402 URL. On 402 the CLI signs a USDC authorization, resends with X-PAYMENT, and returns the result. --search ranks live services by tags + capability (comma-separated terms, best match first).

    npx xdcai marketplace list --search weather,forecast
npx xdcai call https://provider.example/x402/endpoint
Under the hood

Gasless by design

The agent signs an off-chain USDC authorization; a relayer submits it and pays the XDC gas. The agent only ever spends USDC - never gas, never a seed phrase.

Agent

Signs an EIP-3009 USDC authorization off-chain (X-PAYMENT).

Facilitator

Relayer verifies + submits it, paying the XDC gas.

Provider

USDC settles on XDC; the API returns its result.

For LLMs

Deterministic, parseable output

Every command prints exactly one JSON object to stdout. Logs and prompts go to stderr, so parsing stays clean.

# stdout - one JSON object per command
call            → { "ok": true, "status": 200, "paid": "0.01 USDC", "txHash": "0x...", "explorer": "https://xdcscan.com/tx/0x...", "result": { ... } }
wallet transfer → { "success": true, "amount": "0.5", "token": "USDC", "to": "0x...", "txHash": "0x...", "explorer": "https://xdcscan.com/tx/0x..." }
login           → { "loggedIn": true, "email": "...", "address": "0x..." }
whoami          → { "loggedIn": true, "ownerId": "privy:...", "email": "...", "address": "0x..." }

# any failure
                → { "error": "<message>" }   # and a non-zero exit code

# tip: set LOG_LEVEL=error to silence info logs
