⚡ Claude Code Auto Mode: 3 Commands to Start Paying for APIs

Aug 14, 2026 — Claude Code auto mode becomes default. Your agent hits HTTP 402 paywalls. Here's the fix.

Discover APIs (free, no wallet)

Your agent can try any of 306 verified services without registration. Every endpoint is health-probed — dead ones are auto-excluded.

curl -s "https://minia2a.uk/x402/gas"

Returns: gas price + related services your agent can try next

Register (one command, 10 seconds)

No KYC. No credit card. No email. Your agent gets a wallet and 5 free trial calls.

# Sign  minia2a trial:<wallet>:<serviceId>:<unix_ts>  with EIP-191, then send the
  # wallet in the query string plus both headers:
  TS=$(date +%s)
  curl "https://minia2a.uk/x402/gas?wallet=0xYOUR_WALLET" \
    -H "X-Wallet-Signature: 0xYOUR_SIGNATURE" \
    -H "X-Trial-Timestamp: $TS"

  # https://minia2a.uk/register.html signs for you and prints this exact curl.

No wallet is created for you — you sign with your own (self-custody). 5 free trial calls, no registration.

Spend credits (add wallet to any request)

Add ?wallet=YOUR_ADDRESS to any endpoint. Credits auto-deduct, no gas fees, no transaction signing.

export WALLET=0xYOUR_WALLET SERVICE=x402-gas TS=$(date +%s)
export SIG=0xYOUR_SIGNATURE   # EIP-191 personal_sign of: minia2a trial:$WALLET:$SERVICE:$TS
curl "https://minia2a.uk/x402/gas?wallet=$WALLET" \
  -H "X-Wallet-Signature: $SIG" -H "X-Trial-Timestamp: $TS"

Each call costs 1-5 credits. 5 trial calls = 5 API calls. Buy more anytime.

💡 Pro tip: Create a .agent-budget file in your project root. Claude Code auto-mode agents can read it to stay within spending limits.

{"daily_limit_usdc":5, "max_per_call_usdc":1}

Claude Code auto mode becomes the default for Pro, Max, and Team users. The classifier auto-approves safe actions and blocks dangerous ones. When your agent hits an HTTP 402 payment wall, it can autonomously decide to pay — if you've set up a budget.
