With real USDC payments

1. Send USDC on Base to: 0x14a129b3e3Bd154c974118299d75F14626A6157B

2. Copy your transaction hash from basescan.org

3. Set the env var: SWARMRAILS_API_KEY=myapp:0xYOUR_TX_HASH

Each transaction hash is single-use. Payment protocol: x402 on Base.

Payment Protocol

Swarmrails uses the x402 protocol — each USDC transaction on Base blockchain is a single-use API token. No accounts, no subscriptions, no API keys to manage.

Authorization: x402 <macaroon>:0xTRANSACTION_HASH
