⚡ Before You Start

Every endpoint below returns HTTP 402 Payment Required with payment instructions in the payment-required header. Here's how to go from 402 → result:

Option 1 (easiest): Sign a wallet for 5 free trial calls — bring your own wallet and sign:

# Sign "minia2a register: 0xYOUR_WALLET" (EIP-191), then:
curl -s -X POST https://minia2a.uk/api/v1/register-simple \
  -H "Content-Type: application/json" \
  -d '{"name":"my-first-agent","wallet":"0xYOUR_WALLET","signature":"0xYOUR_SIGNATURE"}'

Option 2 (on-chain): no deposit, no balance — pay per call over x402. Probe with ?probe=1, then send USDC on Base to the payTo quoted in the 402 challenge (see payment docs)
